2017-01-01

The potential of a coherent microwave sensor to monitor the vibration characteristics of civil structures has been investigated in the past decade, and successful case studies have been published by different research teams. This remote sensing technique is based on the interferometric processing of real aperture radar acquisitions. Its capability to estimate, simultaneously and remotely, the displacement of different parts of the investigated structures, with high accuracy and repeatability, is its main advantage with respect to conventional sensors. A considerable amount of literature on this technique is available, including various case studies aimed at testing the ambient vibration of bridges, buildings, and towers. In the last years, this technique has been used in Spain for civil structures monitoring. In this paper, three examples of such case studies are described: the monitoring of the suspended bridge crossing the Ebro River at Amposta, the communications tower of Collserola in Barcelona, and an urban building located in Vilafranca del Penedès, a small town close to Barcelona. This paper summarizes the main outcomes of these case studies, underlining the advantages and limitations of the sensors currently available, and concluding with the possible improvements expected from the next generation of sensors.

There are several studies about M1 type vehicle-pedestrian collision injury pattern, and based on them, there has been several changes in automobiles for pedestrian protection. However, the lack of sufficient studies about injury pattern in motorbikes-pedestrian collisions leads to a lack of optimization design of these vehicles. The objective of this research is to study the injury pattern of pedestrians involved in collisions with motorized two-wheeled vehicles. A retrospective descriptive study of pedestrian's deaths after collisions with motorcycles in an urban area, like Barcelona was performed. The cases were collected from the Forensic Pathology Service database of the Institute of Legal Medicine of Catalonia. The selected cases were categorized as pedestrian-motorcycle collision, between January 1st, 2005 and December 31st, 2014. Data were collected from the autopsy, medical, and police report. The collected information was then analyzed using Microsoft Excel statistical functions. Traumatic Brain Injury is the main cause of death in pedestrian hit by motorized two-wheeled vehicles (62.85%). The most frequent injury was the subarachnoid hemorrhage, in 71.4% of cases, followed by cerebral contusions and skull base fractures (65.7%). By contrast, pelvic fractures and tibia fractures only appeared in 28.6%. The study characterizes the injury pattern of pedestrians involved in a collision with motorized two-wheeled vehicles in an urban area, like Barcelona, which has been found to be different from other vehicle-pedestrian collisions, with a higher incidence of brain injuries and minor frequency of lower extremities fractures in pelvis, tibia and fibula.

To study the evolution of the incidence of early-onset neonatal sepsis (EOS) by Streptococcus agalactiae in the area of Barcelona and to analyze failure of compliance with the prevention protocol. A retrospective review was carried out on EOS cases in 8 Health-Care Centers in the Barcelona area between 2004 and 2010. Forty-nine newborns from 48 mothers were diagnosed with EOS. The incidence was 0.29‰ living newborns (0.18-0.47‰), with no significant differences in the fluctuations along the 7 years. The mortality rate was 8.16%. In 68.5% cases the maternal colonization studies were negative, and in 21% these studies were not performed. No risk factors were detected in 58.3% of pregnant women, and 22.9% of births were premature. In 58% of cases intra-partum antibiotic prophylaxis was not administered because it was not indicated, and in 42% due to failure to follow the protocol (3 strains were resistant to erythromycin). Resistance to clindamycin was 33.3%. The Streptococcus agalactiae serotypes more frequently isolated were iii, v, and ia. No significant changes were detected in the incidence of Streptococcus agalactiae EOS in the 7 years of the study. The increased sensitivity of screening methods with the use of molecular techniques, the performance of susceptibility testing of strains isolated from pregnant women, and the improvement of communication between Health-Care Centers, can contribute to a better implementation of the protocol, as well as to reduce the incidence of EOS.

To estimate the health and economic benefits that would result from two scenarios of improved air quality in 57 municipalities of the metropolitan area of Barcelona. We used attributable fractions and life tables to quantify the benefits for selected health outcomes, based on published concentration-response functions and economic unit values. The mean weighted concentration of PM(10) for the study population was estimated through concentration surface maps developed by the local government. The annual mean health benefits of reducing the mean PM(10) exposure estimated for the population in the study area (50microg/m(3)) to the annual mean value recommended by the World Health Organization (20microg/m(3)) were estimated to be 3,500 fewer deaths (representing an average increase in life expectancy of 14 months), 1,800 fewer hospitalizations for cardio-respiratory diseases, 5,100 fewer cases of chronic bronchitis among adults, 31,100 fewer cases of acute bronchitis among children, and 54,000 fewer asthma attacks among children and adults. The mean total monetary benefits were estimated to be 6,400 million euros per year. Reducing PM(10) to comply with the current European Union regulatory annual mean level (40microg/m(3)) would yield approximately one third of these benefits. This study shows that reducing air pollution in the metropolitan area of Barcelona would result in substantial health and economic benefits. The benefits are probably underestimated due to the assumptions made in this study. Assessment of the health impact of local air pollution is a useful tool in public health.

Background The increase in immigration in Barcelona between 2000 and 2008 forced a reorganization of the control of tuberculosis (TB). TB clinical units (TBCU) were created and community health workers (CHW) were gradually included. Objective To understand trends in the incidence of TB among immigrants, their main characteristics and treatment compliance during the period 1991–2013. Design We conducted a cross-sectional population-based study of cases detected among immigrants by the Tuberculosis Program in Barcelona, Spain. Sociodemographic, clinical characteristics and risk factors were described. The annual incidence was calculated for various periods and geographical areas of origin. In the linear trend analysis, a p-value of <0.05 was considered statistically significant. Results We detected 3,284 cases. Incidence decreased from 144.8/100,000 inhabitants in 1991 to 53.4/100,000 in 2013. Individuals born in Pakistan-India-Bangladesh had the highest average annual incidence (675/100,000). In all, 2,156 cases (65.7%) were male. 2,272 (69.2%) had pulmonary TB, of which 48.2% were smear-positive. 33% of the cases (1,093) lived in the inner city. Contact tracing (CT) coverage in smear-positive individuals rose from 56.8% in 1991–1999 to 81.4% in 2000–2013 (p<0.01); this value was less than 50% in people from Africa and Eastern European countries. The case fatality rate was 3.6% overall and 9.8% among those born in high-income countries (p<0.01). The highest rate of treatment default (12.8%) was observed among cases from the Maghreb. The rate of successful treatment increased from 69.9% in 1991–1999 to 87.5% in 2000–2013 (p<0.01). Conclusion The incidence of TB in immigrants is decreasing in Barcelona. Organizational actions, such as incorporating CHWs and TBCUs, have been decisive for the observed improvements. PMID:27749904

International travel and migration have been related with an increase of imported malaria cases. There has been considerable immigration to Barcelona from low-income countries (LIC) in recent years. The objective is to describe the epidemiology and to determine the trends of the disease in Barcelona. Analysis of the cases notified among city residents between 1989 and 2005. Patients were classified as: tourists, voluntary workers, resident immigrants (visiting friends and relatives, VFR) and recently arrived immigrants. An analysis was conducted using the chi2 test and comparison of means. As a measure of association we calculated the Relative Risk (RR) and Odds Ratio (OR) with a Confidence Interval of 95% (CI) and carried out a trends analysis. Of the total of 1,579 imported cases notified, 997 (63.1%) lived in Barcelona city, and 55.1% were male. The mean age of patients was 32.7 years. The incidence increased from 2.4 cases/100,000 in 1989 to 3.5 cases/100,000 in 2005 (RR 1.46 CI:1.36-1.55). This increase was not statistically significant (trends analysis, p = 0.36). In terms of reason for travelling, 40.7% were VFR, 33.6% tourists, 12.1% voluntary workers and 13.6% were recently arrived immigrants. The most frequent species found was Plasmodium falciparum (71.3%), mainly in visitors to Africa (OR = 2.3, CI = 1.7-3.2). The vast majority (82.2%) had had some contact with Africa (35.9% with Equatorial Guinea, a Spanish ex-colony) and 96.6% had not completed chemoprophylaxis. Six deaths were observed, all tourists who had travelled to Africa and not taken chemoprophylaxis (3.9% fatality rate). Over the period studied there is an increase in malaria incidence, however the trend is not statistically significant. Lack of chemoprophylaxis compliance and the association between Africa and P. falciparum are very clear in the imported cases. Most of the patients with malaria did not take chemoprophylaxis.

This study describes the incidence rate of reported lymphogranuloma venereum (LGV) in men who have sex with men (MSM) in Barcelona from 2007 to 2012. Epidemiological, clinical and sexual behaviour characteristics of LGV cases are described. Seroadaptive behaviours as a transmission risk factor were assessed by a telephone questionnaire during 2012. Data were handled on a strictly confidential basis. LGV annual rate ratios in MSM were compared with cases from 2007. Differences were statistically analysed with a Poisson test. The incidence rate of LGV in MSM aged 15-69 years ranged from 32·1/105 MSM per year in 2007 to 182·7/105 MSM per year in 2012. In 2012, 31/51 LGV cases (61%) answered the telephone questionnaire, of which 84% (26/31) were HIV positive, 39% (12/31) reported having sex according to their partners' serostatus and 7% (2/31) used strategic positioning. The incidence of LGV has increased since 2007 and mainly affects HIV-positive MSM. It is probable that seroadaptation has facilitated LGV transmission.

Recent research has assessed the impact of tobacco laws on cardiovascular and respiratory morbidity. In this study, we also examined whether the association between the implementation of the 2005 Spanish smoking ban and hospital admissions for cardiovascular and respiratory diseases varies according to the adjustment for potential confounders. Ecological time series analysis. Residents of Madrid and Barcelona cities (Spain). Data on daily emergency room admissions for acute myocardial infarction, cerebrovascular disease, chronic obstructive pulmonary disease (COPD), and asthma derived from the 2003-2006 Spanish hospital admissions registry. Changes in admission rates between 2006 and the 2003-2005 period were estimated using additive Poisson models allowing for overdispersion adjusted for secular trend in admission, seasonality, day of the week, temperature, number of flu and acute respiratory infection cases, pollution levels, tobacco consumption prevalence and, for asthma cases, pollen count. In Madrid, fully adjusted models failed to detect significant changes in hospital admission rates for any disease during the study period. In Barcelona, however, hospital admissions decreased by 10.2% (95% CI 3.8% to 16.1%) for cerebrovascular diseases and by 16.0% (95% CI 7.0% to 24.1%) for COPD. Substantial changes in effect estimates were observed on adjustment for linear or quadratic trend. Effect estimates for asthma-related admissions varied substantially when adjusting for pollen count in Madrid, and for seasonality and tobacco consumption in Barcelona. Our results confirm that the potential impact of a smoking ban must be adjusted for the underlying secular trend. In asthma-related admissions, pollen count, seasonality and tobacco consumption must be specified in the model. The substantial variability in effects detected between the two cities of Madrid and Barcelona lends strong support for a nationwide study to assess the overall effect of a smoking ban in Spain and identify the causes of the observed heterogeneity.

Background An estimated 30% of HIV cases in the European Union are not aware of their serological status. This study aimed to assess the effectiveness of a pilot HIV partner notification program. Methods HIV cases diagnosed between January 2012 and June 2013 at two healthcare settings in Barcelona were invited to participate in a prospective survey. We identified process and outcome measures to evaluate this partner notification program, including the number of partners identified per interviewed index case, the proportion of partners tested for HIV as a result of the partner notification, and the proportion of new HIV diagnoses among their sex or needle-sharing partners. Results Of the 125 index cases contacted, 108 (86.4%) agreed to provide information about partners. A total of 199 sexual partners were identified (1.8 partners per interviewed index case). HIV outcome was already known for 58 partners (70.7% were known to be HIV-positive), 141 partners were tested as result of partner notification, and 26 were newly diagnosed with HIV. The case-finding effectiveness of the program was 18.4%. Conclusion This pilot program provides evidence of the effectiveness of a partner notification program implemented in healthcare settings. This active partner notification program was feasible, acceptable to the user, and identified a high proportion of HIV-infected patients previously unaware of their status. PMID:25849451

2017-10-01

The construction of the public space has become in the last decades something so important and fundamental in the architecture of the cities, that requires a specific discipline and a concrete study that evaluates the characteristics and actions on it. Not already from an urbanistic perspective but from its own design and constructive perspective, with its character as a place for everyone and for everything, must gather a series of elements that are unique to this space. Barcelona is one of the densest cities in the world that, since the end of the s. XX until our days, tries to solve the public space with a design of quality and optimum. The shortage of public space, which also hosts more than eight million tourists each year, makes it necessary to propose a type of meticulous intervention in order to accommodate all types of users and activities. From the first Universal Exhibition of 1888 through 1929 to the 1992 Olympics as the most important stimulus for this renewal of urban space, Barcelona has been rethinking and evolving in the modus operandi in terms of its urban space. From our professional experience as architects both in the municipal, private and university spheres, we believe that it is our responsibility to confer the public space, that is to say, the design of the urban infrastructure with the attributes necessary to consolidate it in a space Suitable for all without exception and as a place of expression of citizenship. Through the projects of public space developed in our office we will analyze this change of procedure in the construction of squares, parks and other spaces in the city of Barcelona.

The objective of this study was to assess trends in cancer mortality by educational level in Barcelona from 1992 to 2003. The study population comprised Barcelona inhabitants aged 20 years or older. Data on cancer deaths were supplied by the system of information on mortality. Educational level was obtained from the municipal census. Age-standardized rates by educational level were calculated. We also fitted Poisson regression models to estimate the relative index of inequality (RII) and the Slope Index of Inequalities (SII). All were calculated for each sex and period (1992-1994, 1995-1997, 1998-2000, and 2001-2003). Cancer mortality was higher in men and women with lower educational level throughout the study period. Less-schooled men had higher mortality by stomach, mouth and pharynx, oesophagus, larynx and lung cancer. In women, there were educational inequalities for cervix uteri, liver and colon cancer. Inequalities of overall and specific types of cancer mortality remained stable in Barcelona; although a slight reduction was observed for some cancers. This study has identified those cancer types presenting the greatest inequalities between men and women in recent years and shown that in Barcelona there is a stable trend in inequalities in the burden of cancer.

STUDY OBJECTIVE--This study aimed to describe the relationship between health and socioeconomic indicators in the 38 neighbourhoods of the city of Barcelona, Spain. DESIGN--Mortality data for 1983-89 and socioeconomic data for each of the 38 neighbourhoods of Barcelona were used. Mortality indicators used were the comparative mortality figure, the ratio of potential years of life lost, and life expectancy at birth. Socioeconomic indicators were the percentage of unemployed, the percentage of illiteracy, monthly telephone usage, the average power and age of cars, and the average rateable value of buildings and of land. The statistical correlation between socioeconomic indicators and mortality indicators was studied by Spearman's rank correlation coefficient. SETTING--The 38 neighbourhoods of Barcelona, Spain. MEASUREMENTS AND MAIN RESULTS--The comparative mortality figure ranged from 87.41-152.43 and the ratio of potential years of life lost from 74.94-237.31 in both sexes. Both the absolute difference and the ratio of the value for the neighbourhood with lowest mortality and that with highest mortality were larger when premature mortality was examined. Life expectancy at birth ranged from 64.77-75.32 years in men and 75.04-81.51 in women. All correlations between mortality and socioeconomic indicators were high and statistically significant: the higher the unemployment and illiteracy levels and the older the cars, the greater the comparative mortality figure and ratio of potential years of life lost, and the lower the life expectancy (negative correlations). Conversely, the higher the telephone use, the more powerful the cars, and the greater the rateable value, the lower the mortality (negative correlations) and the greater the life expectancy. These correlations were greater in males than in females. The highest correlations were with illiteracy. CONCLUSIONS--This study has detected significant differences in mortality in a large town in the Mediterranean region of Europe. Images PMID:7499987

Long term effects of traffic noise on mortality in the city of Barcelona, 2004-2007.

Numerous studies showing statistically significant associations between environmental noise and adverse health effects already exist for short-term (over one day at most) and long-term (over a year or more) noise exposure, both for morbidity and (albeit to a lesser extent) mortality. Recently, several studies have shown this association to be independent from confounders, mainly those of air pollutants. However, what has not been addressed is the problem of misalignment (i.e. the exposure data locations and health outcomes have different spatial locations). Without any explicit control of such misalignment inference is seriously compromised. Our objective is to assess the long-term effects of traffic noise on mortality in the city of Barcelona (Spain) during 2004-2007. We take into account the control of confounding, for both air pollution and socioeconomic factors at a contextual level and, in particular, we explicitly address the problem of misalignment. We employed a case-control design with individual data. We used deaths resulting from myocardial infarction, hypertension, or Type II diabetes mellitus in Barcelona between 2004 and 2007 as cases for the study, while for controls we used deaths (likewise in Barcelona and over the same period of time) resulting from AIDS or external causes (e.g. accidental falls, accidental poisoning by psychotropic drugs, drugs of abuse, suicide and self-harm, or injuries resulting from motor vehicle accidents). The controls were matched with the cases by sex and age. We used the annual average equivalent A-weighted sound pressure levels for daytime (7-21h), evening-time (21-23h) and night-time (23-7h), and controlled for the following confounders: i) air pollutants (NO2, PM10 and benzene), ii) material deprivation (at a census tract level) and iii) land use and other spatial variables. We explicitly controlled for heterogeneity (uneven distribution of both response and environmental exposures within an area), spatial dependency (of the observations of the response variables), temporal trends (long-term behaviour of the response variables) and spatial misalignment (between response and environmental exposure locations). We used a fully Bayesian method, through the Integrated Nested Laplace Approximation (INLA). Specifically, we plugged the whole model for the exposure into the health model and obtained a linear predictor defined on the entire spatial domain. Separate analyses were carried out for men and for women. After adjusting for confounders, we found that traffic noise was associated with myocardial infarction mortality along with Type II diabetes mellitus in men (in both cases, odds ratios (OR) were around 1.02) and mortality from hypertension in women (ORs around 1.01). Nevertheless, only in the case of hypertension in women, does the association remain statistically significant for all age groups considered (all ages, ≥65 years and ≥75 years).

To analyse the perception, use and satisfaction of a group of immigrants living in Barcelona taking into account their gender, origin and social class. Cross sectional study. City of Barcelona, Spain. A group of 225 immigrant residents and users of social services in the city of Barcelona, from June to July 2012. the level of access and relationship with the public health system of immigrants living in Barcelona was analysed, based on a questionnaire. The responses were analysed in relation to: gender, age, social class, self-perceived health, national origin, time since arrival, and marital status. The large majority (89%) of the population surveyed declared that the most important aspect was «to have been treated with respect» in health services. However, 59.4% reported a perception of «discrimination against immigrants», and 68.4% said that cultural differences affect «totally or partially» the quality of care received. For 66.7% of the participants, health care received in Barcelona is better than in their home country, mainly for its scientific, technical quality, and universal access. Despite the good assessment of universal public health care system this study showed deficiencies of the system in terms of the psychosocial component of health care to immigrants in Barcelona. It is necessary to deepen the study of knowledge and perceptions of minority groups in the current context. Copyright © 2015 Elsevier España, S.L.U. All rights reserved.

Background The objective of this study was to assess trends in cancer mortality by educational level in Barcelona from 1992 to 2003. Methods The study population comprised Barcelona inhabitants aged 20 years or older. Data on cancer deaths were supplied by the system of information on mortality. Educational level was obtained from the municipal census. Age-standardized rates by educational level were calculated. We also fitted Poisson regression models to estimate the relative index of inequality (RII) and the Slope Index of Inequalities (SII). All were calculated for each sex and period (1992–1994, 1995–1997, 1998–2000, and 2001–2003). Results Cancer mortality was higher in men and women with lower educational level throughout the study period. Less-schooled men had higher mortality by stomach, mouth and pharynx, oesophagus, larynx and lung cancer. In women, there were educational inequalities for cervix uteri, liver and colon cancer. Inequalities of overall and specific types of cancer mortality remained stable in Barcelona; although a slight reduction was observed for some cancers. Conclusion This study has identified those cancer types presenting the greatest inequalities between men and women in recent years and shown that in Barcelona there is a stable trend in inequalities in the burden of cancer.

Ambient ultrafine particle number concentrations (PNC) have inhomogeneous spatio-temporal distributions and depend on a number of different urban factors, including background conditions and distant sources. This paper quantitatively compares exposure to ambient ultrafine particles at urban schools in two cities in developed countries, with high insolation climatic conditions, namely Brisbane (Australia) and Barcelona (Spain). The analysis used comprehensive indoor and outdoor air quality measurements at 25 schools in Brisbane and 39 schools in Barcelona. PNC modes were analysed with respect to ambient temperature, land use and urban characteristics, combined with the measured elemental carbon concentrations, NOx (Brisbane) and NO2 (Barcelona). The trends and modes of the quantified weekday average daily cycles of ambient PNC exhibited significant differences between the two cities. PNC increases were observed during traffic rush hours in both cases. However, the mid-day peak was dominant in Brisbane schools and had the highest contribution to total PNC for both indoors and outdoors. In Barcelona, the contribution from traffic was highest for ambient PNC, while the mid-day peak had a slightly higher contribution for indoor concentrations. Analysis of the relationships between PNC and land use characteristics in Barcelona schools showed a moderate correlation with the percentage of road network area and an anti-correlation with the percentage of green area. No statistically significant correlations were found for Brisbane. Overall, despite many similarities between the two cities, school-based exposure patterns were different. The main source of ambient PNC at schools was shown to be traffic in Barcelona and mid-day new particle formation in Brisbane. The mid-day PNC peak in Brisbane could have been driven by the combined effect of background and meteorological conditions, as well as other local/distant sources. The results have implications for urban development, especially in terms of air quality mitigation and management at schools. Copyright © 2015 Elsevier Ltd. All rights reserved.

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.

There is considerable evidence demonstrating socioeconomic inequalities in mortality, some of which focuses on intraurban inequalities. However, all the studies assume that the spatial variation of inequalities is stable over the time. We challenge this assumption and propose two hypotheses: (i) have spatial variations in socioeconomic inequalities in mortality at an intraurban level changed over time? and (ii) as a result of the economic crisis, has the gap between such disparities widened? In this paper, our objective is to assess the effect of the economic recession on the spatio-temporal variation of socioeconomic inequalities in mortality in Barcelona (Catalonia, Spain). We used a spatio-temporal ecological design to analyse mortality inequalities at small area level in Barcelona. Mortality data and socioeconomic indicators correspond to the years 2005 and 2008-2011. We specified spatio-temporal ecological mixed regressions for both men and women using two indicators, neighbourhood and year. We allowed the coefficients of the socioeconomic variables to differ according to the levels and explicitly took into account spatio-temporal adjustment. For men and women both absolute and, above all, relative risks for mortality have increased since 2009. In relative terms, this means that the risk of dying has increased much more in the most economically deprived neighbourhoods than in the more affluent ones. Although the geographical pattern in relative risks for mortality in neighbourhoods in Barcelona remained very stable between 2005 and 2011, socioeconomic inequalities in mortality at an intraurban level have surged since 2009.

Clinical and microbiological descriptive analysis of the outbreak of community legionnaire's disease recorded in the Barcelona's Barcelonesa neighborhood in November 2000. Retrospective review of the epidemiological and clinical manifestations, as well as the evolution of the cases of Legionella pneumophila pneumonia associated with the outbreak and cared of in the Hospital del Mar. The 48 patients evaluated, all of them with confirmed diagnoses, represent 89% of the cases communicated. Seventy-five percent of patients showed some underlying disease, 54% had some criterion for severity, and mortality was 4%. In 81% of cases the detection of the antigen of Legionella pneumophila in urine was the diagnostic method. The detection in urine of the Legionella pneumophila antigen makes possible the early diagnosis of legionnaire's disease, particularly in epidemic outbreaks, which that facilitates the fast establishment of the adequate treatment and contributes to the reduction in mortality even in patients of high risk.

BACKGROUND--Patients affected during the asthma outbreaks caused by soybean dust inhalation in Barcelona presented with sudden onset of severe asthma followed by the rapid relief of symptoms after treatment. Two years after the epidemics ended, a case-control study was conducted in which the clinical, functional, and immunological characteristics of these asthma patients (a randomised sample of asthmatic patients admitted as emergency cases on epidemic days, n = 213) were compared with those of a control group (a random sample of asthmatic patients admitted as emergency cases for attacks of asthma on non-epidemic days, n = 170). METHODS--The study included the administration of the ATS-DLD78 standardised respiratory questionnaire, the measurement of atopy, and performance of spirometric tests and a methacholine inhalation test. RESULTS--Patients with epidemic asthma reported fewer symptoms of asthma, had attended emergency departments less frequently during the previous year for acute attacks of asthma, were taking fewer inhaled corticosteroids at the time of the study, and attended medical follow up less frequently than did the patients with non-epidemic asthma. However, the cases and controls showed no differences in ventilatory capacity or reactivity to the methacholine bronchoprovocation test. CONCLUSIONS--Two years after the end of the soybean epidemics, people affected by epidemic asthma had a favourable prognosis. This finding contrasts with a higher risk of life threatening asthma and death during the epidemics. This paradox could be the result of a complex interaction between host and conditions of exposure.

Field Evidence of Social Influence in the Expression of Political Preferences: The Case of Secessionists Flags in Barcelona

2015-01-01

Models of social influence have explored the dynamics of social contagion, imitation, and diffusion of different types of traits, opinions, and conducts. However, few behavioral data indicating social influence dynamics have been obtained from direct observation in “natural” social contexts. The present research provides that kind of evidence in the case of the public expression of political preferences in the city of Barcelona, where thousands of citizens supporting the secession of Catalonia from Spain have placed a Catalan flag in their balconies and windows. Here we present two different studies. 1) During July 2013 we registered the number of flags in 26% of the electoral districts in the city of Barcelona. We find that there is a large dispersion in the density of flags in districts with similar density of pro-independence voters. However, by comparing the moving average to the global mean we find that the density of flags tends to be fostered in electoral districts where there is a clear majority of pro-independence vote, while it is inhibited in the opposite cases. We also show that the distribution of flags in the observed districts deviates significantly from that of an equivalent random distribution. 2) During 17 days around Catalonia’s 2013 national holiday we observed the position at balcony resolution of the flags displayed in the facades of a sub-sample of 82 blocks. We compare the ‘clustering index’ of flags on the facades observed each day to thousands of equivalent random distributions. Again we provide evidence that successive hangings of flags are not independent events but that a local influence mechanism is favoring their clustering. We also find that except for the national holiday day the density of flags tends to be fostered in facades located in electoral districts where there is a clear majority of pro-independence vote.

OBJECTIVE: To analyse trends in mortality inequalities in Barcelona between 1983 and 1994 by comparing rates in those electoral wards with a low socioeconomic level and rates in the remaining wards. DESIGN: Mortality trends study. SETTING: The city of Barcelona (Spain). SUBJECTS: The study included all deaths among residents of the two groups of city wards. Details were obtained from death certificates. MAIN OUTCOME MEASURES: Age standardised mortality rates, age standardised rates of years of potential life lost, and age specific mortality rates in relation to cause of death, sex, and year were computed as well as the comparative mortality figure and the ratio of standardised rates of years of potential life lost. RESULTS: Rates of premature mortality increased from 5691.2 years of potential life lost per 100,000 inhabitants aged 1 to 70 years in 1983 to 7606.2 in 1994 in the low socioeconomic level wards, and from 3731.2 to 4236.9 in the other wards, showing an increase in inequalities over the 12 years, mostly due to AIDS and drug overdose as causes of death. Conversely, cerebrovascular disease showed a reduction in inequality over the same period. Overall mortality in the 15-44 age group widened the gap between both groups of wards. CONCLUSION: AIDS and drug overdose are emerging as the causes of death that are contributing to a substantial increase in social inequality in terms of premature mortality, an unreported observation in European urban areas.

Objective To determine whether there is an association between nonencephalitic herpes simplex virus 1 (HSV-1) infection and anti-NMDA receptor encephalitis (anti-NMDARE). Methods Antibody testing was performed using samples from 2 cohorts in a case-control observational study. The cohort “Philadelphia” included 16 serum samples of pediatric anti-NMDARE cases and 42 age-matched controls with other neuroinflammatory disorders studied at the Children's Hospital of Philadelphia and University of Pennsylvania. The cohort “Barcelona” contained 23 anti-NMDARE patient samples and 26 age-matched participants with other neuroinflammatory disorders studied at IDIBAPS-Hospital Clinic, University of Barcelona. The presence of HSV-1 IgG antibodies was examined by ELISA. As an additional control, IgG antibodies to cytomegalovirus (CMV) and Epstein-Barr virus viral capsid antigen (EBV-VCA) were determined. Results In each cohort, more participants with anti-NMDARE than controls had anti-HSV-1 IgG antibodies. In the Philadelphia cohort (58 participants), 44% of anti-NMDARE cases had antibodies to HSV-1 compared with 14% controls (OR 4.67, 95% CI 1.3–17.3, p = 0.031). In the Barcelona cohort (49 participants), 52% of participants with anti-NMDARE had antibodies to HSV-1 compared with 31% of controls (OR 2.45, 95% CI 0.7–7.9, p = 0.155). Overall, 49% of anti-NMDARE cases have antibodies to HSV-1 in these 2 combined cohorts compared with 21% of controls (Mantel-Haenszel OR 3.21, 95% CI 1.3–7.7, p = 0.007). Conclusion Past HSV-1 infection was found in significantly more anti-NMDARE cases than controls. This suggests a meaningful association between nonencephalitic HSV-1 infection and development of anti-NMDARE. PMID:29629396

Estimate the health risks and benefits of mode shifts from car to cycling and public transport in the metropolitan area of Barcelona, Spain. We conducted a health impact assessment (HIA), creating 8 different scenarios on the replacement of short and long car trips, by public transport or/and bike. The primary outcome measure was all-cause mortality and change in life expectancy related to two different assessments: A) the exposure of travellers to physical activity, air pollution to particulate matter <2.5 μm (PM2.5), and road traffic fatality; and B) the exposure of general population to PM2.5, modelling by Barcelona Air-Dispersion Model. The secondary outcome was a change in emissions of carbon dioxide. The annual health impact of a shift of 40% of the car trips, starting and ending in Barcelona City, to cycling (n=141,690) would be for the travellers who shift modes 1.15 additional deaths from air pollution, 0.17 additional deaths from road traffic fatality and 67.46 deaths avoided from physical activity resulting in a total of 66.12 deaths avoided. Fewer deaths would be avoided annually if half of the replaced trips were shifted to public transport (43.76 deaths). The annual health impact in the Barcelona City general population (n=1,630,494) of the 40% reduction in car trips would be 10.03 deaths avoided due to the reduction of 0.64% in exposure to PM2.5. The deaths (including travellers and general population) avoided in Barcelona City therefore would be 76.15 annually. Further health benefits would be obtained with a shift of 40% of the car trips from the Greater Barcelona Metropolitan which either start or end in Barcelona City to public transport (40.15 deaths avoided) or public transport and cycling (98.50 deaths avoided).The carbon dioxide reduction for shifting from car to other modes of transport (bike and public transport) in Barcelona metropolitan area was estimated to be 203,251t/CO₂ emissions per year. Interventions to reduce car use and increase cycling and the use of public transport in metropolitan areas, like Barcelona, can produce health benefits for travellers and for the general population of the city. Also these interventions help to reduce green house gas emissions. Copyright © 2012 Elsevier Ltd. All rights reserved.

OBJECTIVE—In recent decades, in most European countries young adult mortality has risen, or at best has remained stable. The aim of this study was to describe trends in mortality attributable to the principal causes of death: AIDS, drug overdose, suicide and motor vehicle traffic accidents, among adults aged between 15 and 34 years in three European cities (Barcelona, Bologna and Munich), over the period 1986 to 1995.
METHODS—The population studied consisted of all deaths that occurred between 1986 and 1995 among residents of Barcelona, Bologna and Munich aged from 15 to 34 years. Information about deaths was obtained from mortality registers. The study variables were sex, age, the underlying cause of death and year of death. Causes of death studied were: drug overdose, AIDS, suicide and motor vehicle traffic accidents. Age standardised mortality rates (direct adjustment) were obtained in all three cities for the age range 15-34. To investigate trends in mortality over the study period Poisson regression models were fitted, obtaining the average relative risk (RR) associated with a one year increment.
RESULTS—Young adult mortality increased among men in Barcelona and Bologna (RR per year: 1.04, 95% confidence intervals (95%CI): 1.03, 1.06 in Barcelona and RR:1.03, 95%CI:1.01, 1.06 in Bologna) and among women in Barcelona (RR:1.02, 95%CI: 1.01, 1.04), with a change in the pattern of the main causes of death attributable to the increase in AIDS and drug overdose mortality. In Munich, the pattern did not change as much, suicides being the main cause of death during the 10 years studied, although they have been decreasing since 1988 (RR:0.92, 95%CI:0.88, 0.96 for men and 0.81, 95%CI: 0.75-0.87 for women).
CONCLUSION—The increase in AIDS mortality observed in the three European cities in the mid-80s and mid-90s has yielded to substantial changes in the pattern of the main causes of death at young ages in Barcelona and Bologna. Munich presented a more stable pattern, with suicide as the main cause of death.

Health professionals and authorities strive to cope with heterogeneous data, services, and statistical models to support decision making on public health. Sophisticated analysis and distributed processing capabilities over geocoded epidemiological data are seen as driving factors to speed up control and decision making in these health risk situations. In this context, recent Web technologies and standards-based web services deployed on geospatial information infrastructures have rapidly become an efficient way to access, share, process, and visualize geocoded health-related information. Data used on this study is based on Tuberculosis (TB) cases registered in Barcelona city during 2009. Residential addresses are geocoded and loaded into a spatial database that acts as a backend database. The web-based application architecture and geoprocessing web services are designed according to the Representational State Transfer (REST) principles. These web processing services produce spatial density maps against the backend database. The results are focused on the use of the proposed web-based application to the analysis of TB cases in Barcelona. The application produces spatial density maps to ease the monitoring and decision making process by health professionals. We also include a discussion of how spatial density maps may be useful for health practitioners in such contexts. In this paper, we developed web-based client application and a set of geoprocessing web services to support specific health-spatial requirements. Spatial density maps of TB incidence were generated to help health professionals in analysis and decision-making tasks. The combined use of geographic information tools, map viewers, and geoprocessing services leads to interesting possibilities in handling health data in a spatial manner. In particular, the use of spatial density maps has been effective to identify the most affected areas and its spatial impact. This study is an attempt to demonstrate how web processing services together with web-based mapping capabilities suit the needs of health practitioners in epidemiological analysis scenarios.

Dozens of studies link acute exposure to particulate matter (PM) air pollution with premature mortality and morbidity, but questions remain about which species and sources in the vast PM mixture are responsible for the observed health effects. Although a few studies exist on the effects of species and sources in U.S. cities, European cities-which have a higher proportion of diesel engines and denser urban populations-have not been well characterized. Information on the effects of specific sources could aid in targeting pollution control and in articulating the biological mechanisms of PM. Our study examined the effects of various PM sources on daily mortality for 2003 through 2007 in Barcelona, a densely populated city in the northeast corner of Spain. Source apportionment for PM ≤ 2.5 μm and ≤ 10 µm in aerodynamic diameter (PM2.5 and PM10) using positive matrix factorization identified eight different factors. Case-crossover regression analysis was used to estimate the effects of each factor. Several sources of PM2.5, including vehicle exhaust, fuel oil combustion, secondary nitrate/organics, minerals, secondary sulfate/organics, and road dust, had statistically significant associations (p < 0.05) with all-cause and cardiovascular mortality. Also, in some cases relative risks for a respective interquartile range increase in concentration were higher for specific sources than for total PM2.5 mass. These results along with those from our multisource models suggest that traffic, sulfate from shipping and long-range transport, and construction dust are important contributors to the adverse health effects linked to PM.

Aplastic anemia is a rare and severe disease. Its incidence varies considerably worldwide. We aimed at describing the epidemiology of this disease, including the incidence, mortality and survival trends, in a well-defined population. Since 1980, a case-control surveillance study of aplastic anemia has been carried out by a cooperative group, in the metropolitan area of Barcelona. Inclusion is dependent on the patient having at least two of the following features: white blood cell count < or = 3.5 x 10(9)/L, platelet count < or = 50 x 10(9)/L, hemoglobin <10 g/L or hematocrit of <30%; when only one of these last two criteria is fulfilled, a reticulocyte count of < or = 30 x 10(9)/L is also required. The bone marrow biopsy has to be compatible with the diagnosis of aplastic anemia. Between 1980 and 2003, a total of 235 cases of aplastic anemia were identified. The overall incidence was 2.34 per million inhabitants per year and the incidence increased with age. Most of the cases were classified as severe or very severe aplastic anemia. Survival rates at 3 months, and at 2 and 15 years after the diagnosis were 73%, 57%, and 51%, respectively. Advanced age and more severe disease at the time of diagnosis were associated with a lower survival rate. There was a trend to a better 2-year survival rate among patients treated with bone marrow transplantation. Forty-nine cases (20.8%) were exposed to drugs reported to be associated with aplastic anemia, and 21 (8.9%) to toxic agents. The incidence of aplastic anemia in Barcelona is low but the case fatality rate is high. Advanced age and severe disease at the time of diagnosis were associated with decreased survival.

The emerging grassroots party Barcelona en Comú won the 2015 Barcelona City Council election. This candidacy was devised by activists involved in the Spanish 15M movement to transform citizen outrage into political change. On the one hand, the 15M movement was based on a decentralized structure. On the other hand, political science literature postulates that parties develop oligarchical leadership structures. This tension motivates to examine whether Barcelona en Comú preserved a decentralized structure or adopted a conventional centralized organization. In this study we develop a computational methodology to characterize the online network organization of every party in the election campaign on Twitter. Results on the network of retweets reveal that, while traditional parties are organized in a single cluster, for Barcelona en Comú two well-defined groups co-exist: a centralized cluster led by the candidate and party accounts, and a decentralized cluster with the movement activists. Furthermore, results on the network of replies also shows a dual structure: a cluster around the candidate receiving the largest attention from other parties, and another with the movement activists exhibiting a higher predisposition to dialogue with other parties.

Objective This study aimed to determine in detail the risk perception of sexually transmitted infections (STIs) and HIV, and the contextual circumstances, in Nigerian commercial sex workers (CSWs) in Barcelona. Design A qualitative study with a phenomenological approach. Setting Raval area in Barcelona. Participants 8 CSWs working in Barcelona. Methods A phenomenological study was carried out with Nigerian CSWs in Barcelona. Sampling was theoretical, taking into account: different age ranges; women with and without a partner; women with and without children; and women participating or not in STI/HIV-prevention workshops. Information was obtained by means of eight semistructured individual interviews. An interpretative content analysis was conducted by four analysts. Results Illegal immigrant status, educational level, financial situation and work, and cultural context had mixed effects on CSW knowledge of, exposure to, and prevention and treatment of STI and HIV. CSWs were aware of the higher risk of STI associated with their occupation. They identified condoms as the best preventive method and used them during intercourse with clients. They also implemented other preventive behaviours such as personal hygiene after intercourse. Control of sexual services provided, health education and healthcare services had a positive effect on decreasing exposure and better management of STI/HIV. Conclusions Nigerian CSWs are a vulnerable group because of their poor socioeconomic status. The perception of risk in this group and their preventive behaviours are based on personal determinants, beliefs and experiences from their home country and influences from the host country. Interventions aimed at CSWs must address knowledge gaps, risk behaviours and structural elements. PMID:26078307

In a context of a shifting environmental, economic and social paradigm, European cities face a situation that is at the same time challenge and opportunity: the need for urban rehabilitation of the vulnerable degraded socio residential fabric. Public administrations in big cities and metropolitan areas are confronted with both the undercurrent need of actualization of the built stock and the rise of urban residential vulnerability. The city of Barcelona, as many others, is the result of multiple phenomena with high urban and social consequences. The socio spatial integration of immigrant population, the touristic rise and gentrification processes are current situations simultaneously taking place in the city. In parallel, a framework of economic crisis in which public investments in urban and social matters decrease, provides a temporal juncture that results into an increase of social polarization and socio economic inequality that becomes evident and expressed in the territory. This research focuses in the case of Barcelona, and presents a methodology based on a system of indicators elaborated through the exploitation of statistical data complemented with very specific data supplied by the Barcelona City Council. The accurate knowledge of socio demographic, socioeconomic and residential and urban characteristics is crucial in order to define the very complex urban dynamics that describe in the city neighbourhoods and areas. Residential vulnerability is defined as an assembly of objective conditions that relate to residential space and indicate situations of social discrimination and structural disadvantage of the population, related to a specific time and context. Thus, it is relevant to analyse the concentration of certain indicators of vulnerability in specific places or neighbourhoods, to contrast its effect on the socio-residential situation and its temporal evolution in order to identify tendencies. The present study contributes to the identification of data sources and a system to calculate the purposed indicators, the elaboration of a GIS analysis in order to determine the characterization of neighbourhoods and census sections according to each indicator, and the identification of areas with a higher degree of problematic based on synthetic analysis. A very relevant knowledge basis that can be used by public policy makers in order to establish measures that define vulnerable areas where to carry out actions that foster urban equality.

A management system for accidental water pollution risk in a harbour: The Barcelona case study

Water quality degradation in harbour domains can have an important negative impact from an economic, touristic and environmental point of view. In that sense, water quality management is becoming a main concern for harbour managers. In this paper, we present the research behind the initiative started in Spanish harbours to control water quality degradation due to accidental pollution. This management system is already operationally running in the Barcelona harbour (NW Mediterranean Sea). The system is based on a recent published risk assessment, which takes into account not only the different activities in the harbour and their inherent risk of accident but also the physical behaviour of harbour waters. In this methodology, a key element is to get hydrodynamic forecasts. Thus, the system is composed of a hierarchy of nested hydrodynamic models covering from the basin scale to the harbour scale and a module that computes the different parameters needed for risk assessment. Special emphasis is made on describing the steps followed for system implementation because such implementation is far from a mere technical problem. The first step is to identify the main forcing factors for the harbour hydrodynamics from both field data and numerical experiments, which has never been done before for the Barcelona harbour. Wind and shelf currents are suggested as the main forcing factors for the harbour circulation. The second step is to identify the requirements that a numerical model must fulfil in order to properly solve the Barcelona harbour's hydrodynamics. A high resolution (< 50 m) three dimensional model able to prognostically calculate temperature and salinity evolution; full air-sea coupling is needed as well. The third step is to investigate the best operational strategy. We have found that small errors in the initial density profiles are acceptable for surface current forecasts but not for deep circulation. A cold start must be avoided and a 72 h spin-up is recommended. The minimum wind forcing resolution has been determined to be 1 h. A scaling factor should be included to account for the energy contribution of the higher frequency processes. Finally, an example of its application to a real case is presented and the comparison to other harbour environmental management systems is discussed.

Using an unprecedentedly large geochemical database, we compare temporal and spatial variations in inhalable trace metal background concentrations in a major city (Barcelona, Spain) and at a nearby mountainous site (Montseny) affected by the urban plume. Both sites are contaminated by technogenic metals, with V, Pb, Cu, Zn, Mn, Sn, Bi, Sb and Cd all showing upper continental crust (UCC) normalised values >1 in broadly increasing order. The highest metal concentrations usually occur during winter at Barcelona and summer in Montseny. This seasonal difference was especially marked at the remote mountain site in several elements such as Ti and Rare Earth Elements, which recorded campaign maxima, exceeding PM10 concentrations seen in Barcelona. The most common metals were Zn, Ti, Cu, Mn, Pb and V. Both V and Ni show highest concentrations in summer, and preferentially fractionate into the finest PM sizes (PM1/PM10 > 0.5) especially in Barcelona, this being attributed to regionally dispersed contamination from fuel oil combustion point sources. Within the city, hourly metal concentrations are controlled either by traffic (rush hour double peak for Cu, Sb, Sn, Ba) or industrial plumes (morning peak of Ni, Mn, Cr generated outside the city overnight), whereas at Montseny metal concentrations rise during the morning to a single, prolonged afternoon peak as contaminated air transported by the sea breeze moves into the mountains. Our exceptional database, which includes hourly measurements of chemical concentrations, demonstrates in more detail than previous studies the spatial and temporal variability of urban pollution by trace metals in a given city. Technogenic metalliferous aerosols are commonly fine in size and therefore potentially bioavailable, emphasising the case for basing urban background PM characterisation not only on physical parameters such as mass but also on sample chemistry and with special emphasis on trace metal content.

Until now, estimates of the Global Burden of Disease (GBD) have mainly been produced on national or regional levels. These general estimates, however, are less useful for city governments who have to take decisions on local scales. To address this gap, we focused on the city-level burden of disease (BD) due to exposures affected by urban and transport planning. We conducted a BD assessment using the Urban and Transport Planning Health Impact Assessment (UTOPHIA) tool to estimate annual preventable morbidity and disability-adjusted life-years (DALYs) under compliance with international exposure recommendations for physical activity (PA), exposure to air pollution, noise, heat, and access to green spaces in Barcelona, Spain. Exposure estimates and morbidity data were available for 1,357,361 Barcelona residents ≥20years (2012). We compared recommended with current exposure levels to estimate the associated BD. We quantified associations between exposures and morbidities and calculated population attributable fractions to estimate the number of attributable cases. We calculated DALYs using GBD Study 2015 background DALY estimates for Spain, which were scaled to Barcelona considering differences in population size, age and sex structures. We also estimated annual health costs that could be avoided under compliance with exposure recommendations. Not complying with recommended levels for PA, air pollution, noise, heat and access to green spaces was estimated to generate a large morbidity burden and resulted in 52,001 DALYs (95% CI: 42,866-61,136) in Barcelona each year (13% of all annual DALYs). From this BD 36% (i.e. 18,951 DALYs) was due to traffic noise with sleep disturbance and annoyance contributing largely (i.e. 10,548 DALYs). Non-compliance was estimated to result in direct health costs of 20.10 million € (95% CI: 15.36-24.83) annually. Non-compliance of international exposure recommendations was estimated to result in a considerable BD and in substantial economic expenditure each year in Barcelona. Our findings suggest that (1) the reduction of motor traffic together with the promotion of active transport and (2) the provision of green infrastructure would result in a considerable BD avoided and substantial savings to the public health care system, as these measures can provide mitigation of noise, air pollution and heat as well as opportunities for PA promotion.

Tobias, Aurelio; Querol, Xavier; Alastuey, Andrés; Amato, Fulvio; Pey, Jorge; Pérez, Noemí; Sunyer, Jordi

2011-01-01

Background: Dozens of studies link acute exposure to particulate matter (PM) air pollution with premature mortality and morbidity, but questions remain about which species and sources in the vast PM mixture are responsible for the observed health effects. Although a few studies exist on the effects of species and sources in U.S. cities, European cities—which have a higher proportion of diesel engines and denser urban populations—have not been well characterized. Information on the effects of specific sources could aid in targeting pollution control and in articulating the biological mechanisms of PM. Objectives: Our study examined the effects of various PM sources on daily mortality for 2003 through 2007 in Barcelona, a densely populated city in the northeast corner of Spain. Methods: Source apportionment for PM ≤ 2.5 μm and ≤ 10 µm in aerodynamic diameter (PM2.5 and PM10) using positive matrix factorization identified eight different factors. Case-crossover regression analysis was used to estimate the effects of each factor. Results: Several sources of PM2.5, including vehicle exhaust, fuel oil combustion, secondary nitrate/organics, minerals, secondary sulfate/organics, and road dust, had statistically significant associations (p < 0.05) with all-cause and cardiovascular mortality. Also, in some cases relative risks for a respective interquartile range increase in concentration were higher for specific sources than for total PM2.5 mass. Conclusions: These results along with those from our multisource models suggest that traffic, sulfate from shipping and long-range transport, and construction dust are important contributors to the adverse health effects linked to PM.

Detection of corrosion is important in cultural heritage assessment. Many structures contain metallic targets embedded in masonry or mortar, and corrosion cab cause important damage. However, detection using non-destructive methods is difficult and highly localized, providing in most cases incomplete results. In order to obtain a more extended analysis, GPR was applied and evaluated to detect damage as consequence of corrosion. This technique is a non-destructive method that covers a large area of study while other methods are constrained to a small areas or specific points. Therefore, some controlled laboratory tests were designed to determine possible differences in radargrams obtained in the case of corroded and non-corroded targets. These analysis allowed to observe that the corrosion seems to increase the attenuation of the radar signal, being difficult to detect targets near the damaged bars. The results were applied to study the mosaic roofs in the Park Guell, in Barcelona. This park is one of the most important Modernista (Art Noveau) complex in Barcelona. It is characterized by structures with roofs and banks with tessellation. Some of these structures are most likely supported by metal elements, and seepage cause important damage observed over the tessellation. The objective of the study was to define the possible existence of those metallic targets, determining their location. And, in the case of existence of metallic elements, defining which are the zones more affected by corrosion. The results demonstrates the existence of metallic supports in many parts, as well as some defined areas that could be damaged.

Cancer mortality inequalities in urban areas: a Bayesian small area analysis in Spanish cities

PubMed Central

2011-01-01

Background Intra-urban inequalities in mortality have been infrequently analysed in European contexts. The aim of the present study was to analyse patterns of cancer mortality and their relationship with socioeconomic deprivation in small areas in 11 Spanish cities. Methods It is a cross-sectional ecological design using mortality data (years 1996-2003). Units of analysis were the census tracts. A deprivation index was calculated for each census tract. In order to control the variability in estimating the risk of dying we used Bayesian models. We present the RR of the census tract with the highest deprivation vs. the census tract with the lowest deprivation. Results In the case of men, socioeconomic inequalities are observed in total cancer mortality in all cities, except in Castellon, Cordoba and Vigo, while Barcelona (RR = 1.53 95%CI 1.42-1.67), Madrid (RR = 1.57 95%CI 1.49-1.65) and Seville (RR = 1.53 95%CI 1.36-1.74) present the greatest inequalities. In general Barcelona and Madrid, present inequalities for most types of cancer. Among women for total cancer mortality, inequalities have only been found in Barcelona and Zaragoza. The excess number of cancer deaths due to socioeconomic deprivation was 16,413 for men and 1,142 for women. Conclusion This study has analysed inequalities in cancer mortality in small areas of cities in Spain, not only relating this mortality with socioeconomic deprivation, but also calculating the excess mortality which may be attributed to such deprivation. This knowledge is particularly useful to determine which geographical areas in each city need intersectorial policies in order to promote a healthy environment. PMID:21232096

This study is concerned with drugs of abuse (DAs) and their metabolites in urban groundwater at field scale in relation to (1) the spatial distribution of the groundwater samples, (2) the depth of the groundwater sample, (3) the presence of DAs in recharge sources, and (4) the identification of processes affecting the fate of DAs in groundwater. To this end, urban groundwater samples were collected in the city of Barcelona and a total of 21 drugs were analyzed including cocainics, amphetamine-like compounds, opioids, lysergics and cannabinoids and the prescribed drugs benzodiazepines. Overall, the highest groundwater concentrations and the largest number of detected DAs were found in zones basically recharged by a river that receives large amounts of effluents from waste water treatment plants (WWTPs). In contrast, the urbanized areas yielded not only lower concentrations but also a much smaller number of drugs, which suggests a local origin. In fact, cocaine and its metabolite were dominant in more prosperous neighbourhoods, whereas the cheaper (MDMA) was the dominant DA in poorer districts. Concentrations of DAs estimated mainly from the waste water fraction in groundwater samples were consistently higher than the measured ones, suggesting that DAs undergo removal processes in both reducing and oxidizing conditions.

The aim of this study was to describe the evolution and epidemiologic characteristics of shigellosis patients over a 25 year period in a large city. Shigellosis is a notifiable disease in Spain since 1988. Cases are analyzed in Barcelona residents included in the registry between 1988-2012. A descriptive analysis by sex, age, mode of transmission and Shigella species is presented. Trend analysis and time series were performed. Of the 559 cases analyzed, 60.15% were males. A sustained increase was observed in the trend since 2008 in males (p<0,05), especially at the expense of males who had no history of food poisoning or travel to endemic areas. The increasing tendency was greater in males from 21 to 60 years, both for S. flexneri (since 2009), and for S. sonnei (since 2004). In 2012 it was noted that in the men with S. flexneri, the 63% were men who have sex with men. An increased trend was detected in men who had no history of food poisoning or travel to endemic areas. This increase points to a change in the pattern of shigellosis, becoming predominantly male and its main mechanism probably by sexual transmission.

We describe a series of cases of syphilis with atypical extracutaneous clinical presentation diagnosed in HIV-infected patients. Retrospective observational study. All cases of syphilis diagnosed in HIV-infected patients during the period between June 2013 and June 2016 in a tertiary hospital of the Barcelona metropolitan area were analysed. A total of 71 cases of syphilis were diagnosed, 32 of them presenting with clinical signs or symptoms. Seven of these cases (9.8% of the total and 21.8% of the symptomatic cases) had atypical presentations with extracutaneous involvement: ocular (4), gastric (1), multiple hepatic abscesses (1) and generalised adenopathies (1). Patients were treated with intramuscular or intravenous penicillin and the clinical and serological evolution was good in all of them. Extracutaneous atypical clinical presentations were observed in 21.8% of symptomatic cases of syphilis in HIV+ patients with ocular involvement being the most freqent.

POLIPHON (POlarization-LIdar PHOtometer Networking) retrieval consists in the vertical separation of two/three particle components in aerosol mixtures, highlighting their relative contributions in terms of the optical properties and mass concentrations. This method is based on the specific particle linear depolarization ratio given for different types of aerosols, and is applied to the new polarized Micro-Pulse Lidar (P-MPL). Case studies of specific climate-relevant aerosols (dust particles, fire smoke, and pollen aerosols, including a clean case as reference) observed over Barcelona (Spain) are presented in order to evaluate firstly the potential of P-MPLs measurements in combination with POLIPHON for retrieving the vertical separation of those particle components forming aerosol mixtures and their properties.

A recent meta-analysis suggested evidence for an effect of exposure to ambient air pollutants on risk of certain congenital heart defects. However, few studies have investigated the effects of traffic-related air pollutants with sufficient spatial accuracy. We estimated associations between congenital anomalies and exposure to traffic-related air pollution in Barcelona, Spain. Cases with nonchromosomal anomalies (n = 2,247) and controls (n = 2,991) were selected from the Barcelona congenital anomaly register during 1994-2006. Land use regression models from the European Study of Cohorts for Air Pollution Effects (ESCAPE), were applied to residential addresses at birth to estimate spatial exposure to nitrogen oxides and dioxide (NOx, NO2), particulate matter with diameter ≤ 10 μm (PM10), 10-2.5 μm (PMcoarse), ≤ 2.5 μm (PM2.5), and PM2.5 absorbance. Spatial estimates were adjusted for temporal trends using data from routine monitoring stations for weeks 3-8 of each pregnancy. Logistic regression models were used to calculate odds ratios (ORs) for 18 congenital anomaly groups associated with an interquartile-range (IQR) increase in exposure estimates. In spatial and spatiotemporal exposure models, we estimated statistically significant associations between an IQR increase in NO2 (12.2 μg/m3) and coarctation of the aorta (ORspatiotemporal = 1.15; 95% CI: 1.01, 1.31) and digestive system defects (ORspatiotemporal = 1.11; 95% CI: 1.00, 1.23), and between an IQR increase in PMcoarse (3.6 μg/m3) and abdominal wall defects (ORspatiotemporal = 1.93; 95% CI: 1.37, 2.73). Other statistically significant increased and decreased ORs were estimated based on the spatial model only or the spatiotemporal model only, but not both. Our results overall do not indicate an association between traffic-related air pollution and most groups of congenital anomalies. Findings for coarctation of the aorta are consistent with those of the previous meta-analysis.

The aim of this study was to examine the effects of climate, season and wastewater quality on contaminant removal efficiency of constructed wetlands implemented in Mediterranean and continental-Mediterranean climate region of Spain. To this end, two experimental horizontal subsurface flow constructed wetlands located in Barcelona and León (Spain) were compared. The two constructed wetland systems had the same experimental set-up. Each wetland had a surface area of 2.95 m(2), a water depth of 25 cm and a granular medium of D(60)=7.3 mm, and was planted with Phragmites australis. Both systems were designed in order to operate with a maximum organic loading rate of 6 g(DBO) m(-2) d(-1). Experimental systems operated with a hydraulic loading rate of 28.5 and 98 mm d(-1) in Barcelona and León, respectively. Total suspended solids, biochemical oxygen demand and ammonium mass removal efficiencies followed seasonal trends, with higher values in the summer (97.4% vs. 97.8%; 97.1% vs. 96.2%; 99.9% vs. 88.9%, in Barcelona and León systems, respectively) than in the winter (83.5% vs. 74.4%; 73.2% vs. 60.6%; 19% vs. no net removal for ammonium in Barcelona and León systems, respectively). During the cold season, biochemical oxygen demand and ammonium removal were significantly higher in Barcelona system than in León, as a result of higher temperature and redox potential in Barcelona. During the warm season, statistical differences were observed only for ammonium removal. Results showed that horizontal subsurface flow constructed wetland is a successful technology for both regions considered, even if winter seemed to be a critical period for ammonium removal in continental climate regions.

To describe the prevalence and correlates of safety belt and mobile phone usage in vehicles in the city of Barcelona (Spain). We performed a study using direct observation with a cross-sectional design. We selected 2,442 private cars, commercial vehicles, and taxis from all districts of Barcelona. The prevalence of people not wearing safety belt was 10.5% among drivers, 4.6% among front seat passengers, and 32.2% among some of the rear passengers. It was higher among the passengers than among the drivers, regardless of the type of the vehicle. The prevalence of mobile phone usage while driving during a moment of the trip was 3.8%. Our study shows noticeably high prevalence of people not wearing safety belt in the rear seats. Moreover, four out of one hundred drivers still use the mobile phone while driving during a moment of the trip. Copyright © 2013 SESPAS. Published by Elsevier Espana. All rights reserved.

2017-01-04

Hepatocellular carcinoma has a poor prognosis; few patients can undergo surgical curative treatment according to Barcelona Clinic Liver Cancer guidelines. Progress in surgical techniques has led to operations for more patients outside these guidelines. Our case shows a patient with intermediate stage hepatocellular carcinoma presenting a good outcome after curative treatment. We report the case of an 80-year-old Moroccan man, who was positive for hepatitis c virus, presenting an intermediate stage hepatocellular carcinoma (three lesions between 20 and 60 mm). He presented a complete tumor necrosis after portal vein embolization and achieved 24-month disease-free survival after surgery. Perioperative care in liver surgery and multidisciplinary discussion can help to extend indications for liver resection for hepatocellular carcinoma outside European Association for the Study of the Liver/American Association for the Study of Liver Diseases recommendations and offer a curative approach to selected patients with intermediate and advanced stage hepatocellular carcinoma.

The homeless are at very high risk of suffering tuberculosis (TB). The aims of this study were to determine the prevalence and risk factors for tuberculosis infection and disease among the homeless in Barcelona and to evaluate the roles of case finding and contact investigation. Observational prevalence study carried out between 1997 and 1998. 447 homeless patients (394 men and 53 women) were evaluated before admission to shelters and free-meal services. At the same time, 48 co-residents with smear-positive TB patients in 2 long-term shelters were evaluated too. A chest X-ray and Tuberculin Skin Test were performed on all subjects. Sputum smears were processed by the Ziehl-Neelsen and Löwenstein-Jensen procedures in patients with radiographic findings consistent with pulmonary TB. Of the 447 homeless examined, 335 (75%) were infected with Mycobacterium tuberculosis. Active pulmonary TB was diagnosed in five persons (1.11%), and 62 (13.8%) had radiographic evidence of inactive pulmonary TB. Tuberculosis infection was associated with age and smoking, but not with sex or alcohol abuse. No significant differences in infection rates were found between the main group and 48 homeless co-residents of smear-positive subjects. Only 16.9% of the homeless with active TB in Barcelona in the same period were diagnosed through active case-finding, the remainder being mainly detected in hospitals (69.8%) and other several centres (13.3%). Homeless individuals have a very high risk of TB infection and disease and contact investigation requires specific methods for them. Programmes of screening and supervised treatment should be ensured in this group.

Introduction Sexually transmitted infections (STIs) and HIV are a serious global public health issue. These diseases are largely preventable, as they are directly and indirectly associated with potentially modifiable factors, including socioeconomic conditions. Sexual transmission is responsible for over 75% of new HIV infections worldwide. Moreover, commercial sex workers and their clients are two of the groups at the highest risk of acquiring and transmitting these infectious diseases, due to an extensive number of sexual encounters and the various factors related to commercial sex situations. This qualitative study aims to deepen the understanding of the risk perception of STIs and HIV and their associated factors in Nigerian commercial sex workers in the city of Barcelona. Methods and analysis This is a qualitative, descriptive, interpretive study based on a social constructivist and phenomenological perspective conducted on a saturated sample of Nigerian commercial sex workers in the city of Barcelona. Data will be collected through semistructured individual and triangular group interviews. Information will be examined using a sociological discourse analysis, allowing us to understand the social and individual factors related to the risk perception of STIs and HIV in commercial sex workers. Discussion Qualitative studies are an important element in identifying individual, social and contextual factors directly or indirectly related to the health/disease process. This qualitative study will provide essential knowledge to improve health promotion, prevention strategies and effective management of STIs both for commercial sex workers and their clients. Ethics This study has been approved by the clinical research ethics committee (CEIC) of IDIAP Jordi Gol in Barcelona, 2012. PMID:23901029

Intensive vegetable production areas were surveyed in the provinces of Almería (35 sites) and Barcelona (22 sites), Spain, to determine the incidence and identity of Meloidogyne spp. and of fungal parasites of nematode eggs. Two species of Meloidogyne were found in Almería—M. javanica (63% of the samples) and M. incognita (31%). Three species were found in Barcelona, including M. incognita (50%), M. javanica (36%), and M. arenaria (14%). Solanaceous crops supported larger (P < 0.05) nematode numbers than cucurbit crops in Almería but not in Barcelona. Fungal parasites were found in 37% and 45% of the sites in Almería and Barcelona, respectively, but percent parasitism was never greater than 5%. Nine fungal species were isolated from single eggs of the nematode. The fungi included Verticillium chlamydosporium, V. catenulatum, Fusarium oxysporum, F. solani, Fusarium spp., Acremonium strictum, Gliocladium roseum, Cylindrocarpon spp., Engiodontium album, and Dactylella oviparasitica. Two sterile fungi and five unidentified fungi also were isolated from Meloidogyne spp. eggs. PMID:19265964

Studies on health-related quality of life (HRQoL) inequalities according to sexual orientation are scarce. The aim of this study was to assess HRQoL inequalities between lesbian, gay, and bisexual (LGB) people and heterosexuals in the 2011 Barcelona population, to describe the extent to which sociodemographic characteristics, health-related behaviors, and chronic conditions could explain such inequalities, and to understand if they are sexual orientation inequities. In the 2011 Barcelona Health Interview Survey 3277 adults answered the EQ-5D, which measures five dimensions of HRQoL summarized into a single utility index (1 = perfect health, 0 = death). To assess HRQoL differences by sexual orientation we constructed Tobit models for the EQ-5D index, and Poisson regression models for the EQ-5D dimensions. In both cases, nested models were constructed to assess the mediator role of selected variables. After adjusting by socio-demographic variables, the LGB group presented a significantly lower EQ-5D index than heterosexuals, and higher prevalence ratios of problems in physical EQ-5D dimensions among both genders: adjusted prevalence ratio (aPR) = 1.70 for mobility (p = 0.046) and 2.11 for usual activities (p = 0.019). Differences in mental dimensions were only observed among men: aPR = 3.15 for pain/discomfort (p = 0.003) and 2.49 for anxiety/depression (p = 0.030). All these differences by sexual orientation disappeared after adding chronic conditions and health-related behaviors in the models. The LGB population presented worse HRQoL than heterosexuals in the EQ-5D index and most dimensions. Chronic conditions, health-related behaviors and gender play a major role in explaining HRQoL differences by sexual orientation. These findings support the need of including sexual orientation into the global agenda of health inequities.

Flood risk changes in Mediterranean Region integrate multiple factors, some of them related with the hazard (i.e. rainfall intensity), the vulnerability and exposure (i.e. population or assets), feedback processes that affect both hazard and vulnerability (i.e. urbanization of flood prone areas), mitigation and adaptation measures (i.e. rainwater tanks or early warning systems), and the available information used to estimate flood events (i.e. newspapers or gauged data). Flood events in the West Mediterranean region are usually produced as a consequence of very intense and local precipitation, mainly recorded on late summer and autumn that can give place to flash-floods in little torrential rivers (usually non-permanent flows) or urban floods. The Metropolitan Area of Barcelona (AMB), Spain, constitutes a good paradigm of a Mediterranean coast region, with strong urbanization of flood prone areas and high population density in an area crossed by numerous streams. The AMB is constituted by 36 municipalities with a total population above 3.200.000 inhabitants in an extension of 636 km². The major part of the population is concentrated between the Besós River and the Llobregat River, the Littoral Range and the Mediterranean Sea. Although both rivers have experienced catastrophic flood events (i.e. 25 September 1962, 815 deaths; 19-23 September 1971, 19 deaths; October 1987, 8 deaths), the most frequent situation is related with floods in non-permanent streams. Their main impacts are consequence of drainage and runoff problems and can affect both urban and rural areas. This contribution explores the evolution of land uses, population and precipitation from the middle of the 20th century until now, and how these changes have affected (or not), the flood risk. To do it, daily and sub-daily rainfall series, discharge series for the Llobregat and Besós Rivers, population data and land use changes have been analyzed. Future precipitation projections provided by an ensemble of regional models (ENSEMBLES project) have been also considered. Flood events have been obtained from newspapers, reports and insurance data. The role played by prevention measures, particularly in the specific case of Barcelona, which has been recognized by UNISDR (United Nations International Strategy for Disaster Reduction) as resilient city in front of floods, is also presented. Results confirm the strong role played by the increase of urban surface (from less than 15% in 1956 to near 40% in 2009) and explore future adaptation measures in the context of the 2030 Agenda for Sustainable Development. This work has been supported by the Spanish project HOPE and the Metropolitan Area of Barcelona, and developed by an interdisciplinary team that include experts from hydrology, meteorology, geography, environmental sciences and architecture.

The purpose of this study was to describe the variation in listeriosis infection incidence during pregnancy over a 25-year period based on salient clinical and laboratory features compiled in a tertiary referral hospital and to depict the clinical characteristics of these cases. A cohort was created of all cases of listeriosis in pregnant women or their neonates (early-onset form) diagnosed between 1985 and 2010. Forty-three cases of perinatal listeriosis were diagnosed among the 82,320 hospitalised pregnant women (incidence 0.5‰). Whereas the incidence remained almost constant at 0.24‰ until 2000, an increasing incidence was observed from then on, reaching 0.86‰ during the last years of the study period. A four-fold increase in listeriosis rate during pregnancy has occurred in recent years, with poorer outcome for those cases occurring before 28 weeks and for those in which early antibiotic treatment was not provided. These results should raise the awareness of the agencies and professionals involved in prenatal care.

Deposition of dissolved organic nitrogen (DON) in both bulk precipitation (BD) and canopy throughfall (TF) has been measured for the first time in the western Mediterranean. The study was carried out over a year from 2012 to 2013 at four evergreen holm oak forests located in the Iberian Peninsula: two sites in the Province of Barcelona (Northeastern Spain), one in the Province of Madrid (central Spain) and the fourth in the Province of Navarra (Northern Spain). In BD the annual volume weighted mean (VWM) concentration of DON ranged from 0.25 mg l(-1) in Madrid to 1.14 mg l(-1) in Navarra, whereas in TF it ranged from 0.93 mg l(-1) in Barcelona to 1.98 mg l(-1) in Madrid. The contribution of DON to total nitrogen deposition varied from 34% to 56% in BD in Barcelona and Navarra respectively, and from 38% in Barcelona to 72% in Madrid in TF. Agricultural activities and pollutants generated in metropolitan areas were identified as potential anthropogenic sources of DON at the study sites. Moreover, canopy uptake of DON in Navarra was found in spring and autumn, showing that organic nitrogen may be a supplementary nutrient for Mediterranean forests, assuming that a portion of the nitrogen taken up is assimilated during biologically active periods.

To analyze the trend in socioeconomic inequalities in all-cause mortality in Barcelona from 1983 to 2004. We performed an ecological study of trends over 4 cross-sections (1983-1988, 1989-1994, 1995-1999 and 2000-2004), with the basic health area (BHA) as the unit of analysis. The study population consisted of men and women aged 20 years or more living in Barcelona. The information sources were the mortality registry, the municipal census and the census of inhabitants and dwellings. The age- and sex-specific mortality rate (ASMR) for all causes was used as the dependent variable. As the independent variable, a composite index of socioeconomic deprivation of the BHA was calculated; BHAs were grouped in quartiles according to the values on the index. Poisson models were adjusted to estimate the relative risk of mortality from all causes in the 4 groups of BHA, stratified by age groups and sex. In all the study periods, inequalities in mortality were found, depending on the BHA of residence, both for men and for women: the ASMR of the most deprived BHAs were greater than those of less deprived BHA, and were greater among men than among women. Likewise, relative risks in the youngest age groups were higher than in the oldest age groups. However, from the second to fourth study periods, inequalities decreased in absolute and relative terms, especially among men. Inequalities in mortality persist in BHA in Barcelona but have decreased over the last 2 decades. Public policies should take this information into account when tackling inequalities among BHA.

García‐Altés, A; Pérez, K

2007-01-01

The objective of this article is to assess the total economic costs of road traffic crashes in Barcelona, a metropolitan city located in Southern Europe. A cost‐of‐illness study was conducted using a prevalence approximation, a societal and healthcare system perspective, and a 1‐year time horizon. Results were measured in terms of Euros in 2003. Total costs of road traffic crashes in Barcelona in 2003 were €367 million. Direct costs equalled €329 million (89.8% of total costs), including property damage costs, insurance administration costs and hospital costs. Police, emergency costs and transportation costs had a minimum effect on total direct costs. Indirect costs were €37 million, including lost productivity due to hospitalization and mortality. The results of the sensitivity analysis showed the upper limit of total economic cost of road traffic crashes in Barcelona to be €782 million. This is the first study to estimate the costs of road traffic crashes for a city in a developed country. The importance of the problem calls for further interventions to reduce road traffic crashes.

This study examines the relationship between neighbourhood green space, the neighbourhood social environment (social cohesion, neighbourhood attachment, social contacts), and mental health in four European cities. The PHENOTYPE study was carried out in 2013 in Barcelona (Spain), Stoke-on-Trent (United Kingdom), Doetinchem (The Netherlands), and Kaunas (Lithuania). 3771 adults living in 124 neighbourhoods answered questions on mental health, neighbourhood social environment, and amount and quality of green space. Additionally, audit data on neighbourhood green space were collected. Multilevel regression analyses examined the relation between neighbourhood green space and individual mental health and the influence of neighbourhood social environment. Mental health was only related to green (audit) in Barcelona. The amount and quality of neighbourhood green space (audit and perceived) were related to social cohesion in Doetinchem and Stoke-on-Trent and to neighbourhood attachment in Doetinchem. In all four cities, mental health was associated with social contacts. Neighbourhood green was related to mental health only in Barcelona. Though neighbourhood green was related to social cohesion and attachment, the neighbourhood social environment seems not the underlying mechanism for this relationship.

Influences of natural emission sources (wildfires and Saharan dust) on the urban organic aerosol in Barcelona (Western Mediterranean Basis) during a PM event.

van Drooge, Barend L; Lopez, Jordi F; Grimalt, Joan O

2012-11-01

The urban air quality in Barcelona in the Western Mediterranean Basin is characterized by overall high particulate matter (PM) concentrations, due to intensive local anthropogenic emissions and specific meteorological conditions. Moreover, on several days, especially in summer, natural PM sources, such as long-range transported Saharan dust from Northern Africa or wildfires on the Iberian Peninsula and around the Mediterranean Basin, may influence the levels and composition of the organic aerosol. In the second half of July 2009, daily collected PM(10) filter samples in an urban background site in Barcelona were analyzed on organic tracer compounds representing several emission sources. During this period, an important PM peak event was observed. Individual organic compound concentrations increased two to five times during this event. Although highest increase was observed for the organic tracer of biomass burning, the contribution to the organic aerosol was estimated to be around 6 %. Organic tracers that could be related to Saharan dust showed no correlation with the PM and OC levels, while this was the case for those related to fossil fuel combustion from traffic emissions. Moreover, a change in the meteorological conditions gave way to an overall increase of the urban background contamination. Long-range atmospheric transport of organic compounds from primary emissions sources (i.e., wildfires and Saharan dust) has a relatively moderate impact on the organic aerosol in an urban area where the local emissions are dominating.

Our results show that the contribution of urban forests regulating services to abate pollution is substantial in absolute terms, yet modest when compared to overall city levels of air pollution and GHG emissions. We conclude that in order to be effective, green infrastructure-based efforts to offset urban pollution at the municipal level have to be coordinated with territorial policies at broader spatial scales.

Although Candida albicans (CA) is the most common cause of Candida bloodstream infections (BSIs), recent studies have observed an increasing percentage of candidaemias caused by non-albicans Candida species (NAC). In the present study, we attempted to identify the predictors of candidaemia due to NAC compared to CA. We analyzed data from an active population-based surveillance in Barcelona (Spain) from January 2002 to December 2003. Factors associated with NAC fungaemia were determined by multivariate analysis. A total of 339 episodes of Candida BSI, in 336 patients (median age 63 years, interquartile range: 41-72 years), were included. CA was the most commonly isolated (52%), followed by Candida parapsilosis (23%), Candida tropicalis (10%), Candida glabrata (8.6%), Candida krusei (3.4%) and other NAC spp. (3%).Overall, 48% of cases were due to NAC spp. Multivariate logistic regression analysis identified factors associated with a risk of BSI due to NAC spp.: having received a haematologic transplant (OR 10.8; 95% CI 1.31-90.01; p 0.027), previous fluconazole exposure (OR 4.47; 95% CI 2.12-9.43; p <0.001) and neonatal age (OR 4.42; 95% CI 1.63-12.04; p 0.004). Conversely, previous CA colonization (OR 0.33; 95% CI 0.19-0.57; p 0.001) and previous antibiotic use (OR 0.42; 95% CI 0.21-0.85; p 0.017) were associated with CA fungaemia compared to NAC. In conclusion, NAC candidaemia comprised 48% of cases in our series. Predictors of NAC include having received a haematologic transplant, neonatal age and previous fluconazole use. © 2010 The Authors.

This study analyze the duration of episodes of work absence due to non work-related diseases in Catalonia by health regions, assuming a homogeneous distribution of durations between health regions. A retrospective cohort study of 811.790 episodes in 2005 and followed to episode closure through July 2007 provided by the Institut Català d'Avaluacions Mèdiques, describing their median duration (MD) in days for each of the seven health regions of Catalonia. The probability of returning to work was plotted according to Wang_Chang survival curves and median durations were then compared using the Barcelona health region as the referent group. Results were extended through stratification by sex. The Camp de Tarragona health region had the shortest MD (5 days), while the episodes in the Alt Pirineu i Aran region had the longest (MD, 13 days). The Barcelona health region had a MD of 7 days as was the case for Cataluña Central. MD in Girona was 8 days, and in Lleida and Terres de l'Ebre it was 9 days. This latter region also had the highest median duration 13 days. The are significant differences in the duration of work absence between the health regions of Catalonia. These differences persisted after adjusting for age, management of episodes and social security system status, in both men and women.

Urban Health Equity Assessment and Response Tool (HEART) is a tool developed by the World Health Organization whose objective is to provide evidence on urban health inequalities so as to help to decide the best interventions aimed to promote urban health equity. The aim of this paper is to describe the experience of implementing Urban HEART in Barcelona city, both the adaptation of Urban HEART to the city of Barcelona, its use as a means of identifying and monitoring health inequalities among city neighbourhoods, and the difficulties and barriers encountered throughout the process. Although ASPB public health technicians participated in the Urban HEART Advisory Group, had large experience in health inequalities analysis and research and showed interest in implementing the tool, it was not until 2015, when the city council was governed by a new left-wing party for which reducing health inequalities was a priority that Urban HEART could be used. A provisional matrix was developed, including both health and health determinant indicators, which allowed to show how some neighbourhoods in the city systematically fare worse for most of the indicators while others systematically fare better. It also allowed to identify 18 neighbourhoods-those which fared worse in most indicators-which were considered a priority for intervention, which entered the Health in the Barcelona Neighbourhoods programme and the Neighbourhoods Plan. This provisional version was reviewed and improved by the Urban HEART Barcelona Working Group. Technicians with experience in public health and/or in indicator and database management were asked to indicate suitability and relevance from a list of potential indicators. The definitive Urban HEART Barcelona version included 15 indicators from the five Urban HEART domains and improved the previous version in several requirements. Several barriers were encountered, such as having to estimate indicators in scarcely populated areas or finding adequate indicators for the physical context domain. In conclusion, the Urban HEART tool allowed to identify urban inequalities in the city of Barcelona and to include health inequalities in the public debate. It also allowed to reinforce the community health programme Health in the Barcelona Neighbourhoods as well as other city programmes aimed at reducing health inequalities. A strong political will is essential to place health inequalities in the political agenda and implement policies to tackle them.

Night shift work, exposure to light at night (ALAN) and circadian disruption may increase the risk of hormone-dependent cancers. We evaluated the association of exposure to ALAN during sleeping time with breast and prostate cancer in a population based multicase-control study (MCC-Spain), among subjects who had never worked at night. We evaluated chronotype, a characteristic that may relate to adaptation to light at night. We enrolled 1,219 breast cancer cases, 1,385 female controls, 623 prostate cancer cases, and 879 male controls from 11 Spanish regions in 2008-2013. Indoor ALAN information was obtained through questionnaires. Outdoor ALAN was analyzed using images from the International Space Station (ISS) available for Barcelona and Madrid for 2012-2013, including data of remotely sensed upward light intensity and blue light spectrum information for each geocoded longest residence of each MCC-Spain subject. Among Barcelona and Madrid participants with information on both indoor and outdoor ALAN, exposure to outdoor ALAN in the blue light spectrum was associated with breast cancer [adjusted odds ratio (OR) for highest vs. lowest tertile, OR=1.47; 95% CI: 1.00, 2.17] and prostate cancer (OR=2.05; 95% CI: 1.38, 3.03). In contrast, those exposed to the highest versus lowest intensity of outdoor ALAN were more likely to be controls than cases, particularly for prostate cancer. Compared with those who reported sleeping in total darkness, men who slept in "quite illuminated" bedrooms had a higher risk of prostate cancer (OR=2.79; 95% CI: 1.55, 5.04), whereas women had a slightly lower risk of breast cancer (OR=0.77; 95% CI: 0.39, 1.51). Both prostate and breast cancer were associated with high estimated exposure to outdoor ALAN in the blue-enriched light spectrum. https://doi.org/10.1289/EHP1837.

Objectives To evaluate changes in the prevalence of HIV infection among young heroin users in three Spanish cities, and their association with harm reduction programmes (HRPs). Methods Two cross sectional studies. The 1995 study included 596 users; half were street recruited and half were recruited at drug treatment centres. The 2001–03 study included 981 street recruited users. Face to face interviews were conducted using a structured questionnaire. Samples for HIV testing (saliva in 1995 and dried blood spot in 2001–03) were collected. Results The proportion who had ever injected (IDUs) decreased in all three cities. HIV prevalence in IDUs decreased by half in Barcelona (44.1% to 20.8%) and Seville (44.2% to 22.2%), but remained constant in Madrid (36.8% and 34.9%). This difference was attributable to a decrease in HIV prevalence in long term IDUs in Barcelona and Seville, but not in Madrid. The crude odds ratio for HIV prevalence in Madrid compared with Barcelona in long term IDUs was 2.3 (95%CI 1.4 to 3.7), increasing to 3.1 (95%CI 1.5 to 6.2) after adjusting for sociodemographic and risk factors. HIV prevalence in short term IDUs was similar in all cities. In 1992 Barcelona already had 20 heroin users in methadone maintenance programmes (MMPs) per 10 000 population aged 15–49 years; Seville reached this rate in 1994, and Madrid, not until 1998. Conclusions The prevalence of HIV infection did not decrease in long term injectors in Madrid. The delayed implementation of HRPs, especially MMPs, may be the most plausible hypothesis. This finding should shed light on decision making in countries in a similar epidemiological and sociological situation. PMID:16698987

To describe knowledge of electronic cigarettes (e-cigarettes) and their perceived harmfulness in the population of Barcelona in 2013-2014. We used participants from a longitudinal study of a representative sample of the adult population in the city of Barcelona (n=736). The field work was conducted between May 2013 and February 2014. Awareness of e-cigarette was 79.2%. The average level of knowledge was 4.4 points out of 10; there were statistically significant differences according to age, educational level, tobacco consumption, and nicotine dependence. Most participants had learned about e-cigarettes through traditional media (57.8%). Nearly half (47.2%) of the participants believed that e-cigarettes are less harmful than conventional cigarettes. Advertising of e-cigarettes in the media should be regulated because there is still scarce scientific evidence about the usefulness and harmful effects of these devices. Copyright © 2014 SESPAS.

When an astronaut transitions from a low to high gravitational environment, fluid shifts from the head towards the feet resulting in orthostatic intolerance and syncope. Ground based experiments have shown that by stimulating the cardiovascular system via simple mental stressors, syncope can be delayed, potentially enabling astronauts to reach assistance before loss of consciousness. However, the effect of mental stressors on the stimulation of the cardiovascular system in gravitational environments different than that of Earth's is unknown. As such, this paper investigates the effects that mental stressors under various gravitational environments. To do this, a pilot study was performed in which two participants were flown on two separate parabolic flights that simulated hyper and hypogravity conditions. The plane used was an Aerobatic Single-Engine Cap-10B plane (twin seater), and each participant executed 11 parabolas. The participants were the winners of the Barcelona Zero-G Challenge 2011 organized by UPC Universitat Politècnica de Catalunya-BarcelonaTech and Aeroclub Barcelona-Sabadell. Measurements were made of the participants' hemodynamic and autonomic response throughout the parabolas, using a Chronocord: high precision HRV monitor. Comparisons of the baseline response without mental stressors, and the response with mental stressors during different gravitational loading conditions were made. It was observed that there is an increase in cardiovascular activity during hypo- and hyper-gravity when performing mental arithmetic. Our results show that the twin seater aerobatic single engine CAP-10B aicraft can provide changing gravitational loading conditions for enough periods to study changes in physiological systems.

The metropolitan area of Barcelona is the most densely populated metropolitan area on the Mediterranean coast. Several studies have reported the presence of canine heartworm disease in this region; however, there are no published epidemiological data regarding feline heartworm in this region and the prevalence in this species remains unknown. Serum samples from 758 cats living in the metropolitan area of Barcelona (Spain) were collected between 2012 and 2013. To establish the seroprevalence of heartworm infection in cats, serological techniques for anti-D.immitis and anti-Wolbachia antibody detection were used while a commercial ELISA test kit was used to detect circulating D.immitis antigens. Of these samples, 11.47% were positive to D.immitis and Wolbachia surface protein antibodies and 0.26% were positive to D.immitis antigens. The higher antibody seroprevalences were found in the areas that follow the courses of the rivers Llobregat and Anoia (Baix Llobregat 11.5%, Vallés Occidental 13.2%; Barcelonés 11.7%) where humidity and vegetation favour the development of the mosquito vectors. High antibody seroprevalences were also found in the urban areas (Barcelona city 13.1%; Sabadell 15.5%), which demonstrates that city cats are also at risk from D.immitis infection. Generally, in Spain cats do not receive prophylactic treatment and therefore the risk of infection is higher in this species than in dogs. Adequate prophylactic plans should be implemented in the feline population. This is the first epidemiologic study on feline heartworm infection to be carried out in continental Spain.

Biomedical practices from a patient perspective. Experiences of Polish female migrants in Barcelona, Berlin and London.

PubMed

Main, Izabella

2016-08-01

This paper focuses on the diversity in patients' experience of bio-medicine and contrasts it with the normative view characteristic of health professionals. Ethnographic fieldwork among Polish migrant women in London, Barcelona and Berlin included interviews about their experiences with local healthcare and health professionals. Themes drawn from the narratives are differences between the cities in terms of communication between patients and health professionals, respect for patients' choices and dignity, attitudes to pregnancy and birth (different levels of medicalization), and paediatric care. It is argued that patients continuously negotiate among their own views and expectations based on previous experiences and knowledge from personal communication; internet forums and publications; and the offer of medical services in the countries of their settlement. Patients experience pluralism of therapeutic traditions within and outside bio-medicine. In turn, representatives of bio-medicine are rarely aware of other medical practices and beliefs and this leads to various misunderstandings. By highlighting the pluralism of medical practices in European countries and the increasing mobility of patients, this case study has useful implications for medical anthropologists and health professionals in a broader Western context, such as raising sensitivity to different communication strategies and a diversity of curing traditions and expectations.

[Reproducibility of the use of classifications of causes of death in the context of inquiries in perinatal mortality].

The objective of this study was to verify the reliability of the classifications of perinatal mortality causes. An independent observer coded the cases of perinatal death (n = 152) collected in the Encuesta Confidencial de Mortalidad Perinatal de Barcelona (ECMP, Confidential Perinatal Mortality Inquiry of Barcelona), by using both the Aberdeen classification system (regarding obstetric factors) and the Wigglesworth classification system (according to the initial pathological cause), with the same information used previously by the ECMP Commission. For the Aberdeen classification, the observed concordance index (Po) was 86% and the Kappa coefficient (K) 0.77 (95% CI: 0.68-0.86). For the Wigglesworth classification, the figures were 89% and 0.82 (95% CI: 0.74-0.90), respectively. The disagreement was mainly due to differences in the interpretation of the sequence of death, minimal information available in order to classify the cause of death, and misunderstanding of the existing information. To a lesser extent, the disagreement was caused by a failure to comply with the rules laid down for classifications. The assessment of the causes of death was not significantly influenced by birth weight, gestational age, time of death or the presence of necropsy. These results support the use of classifications of perinatal mortality causes in the context of confidential inquiries.

Asbestos is a first level carcinogen. However, few epidemiological studies analyse the risk and protective factors associated with asbestos-related diseases and follow up these conditions in the general population. Pleural mesothelioma, caused by inhalation of asbestos fibres at work, at home or in the environment, is the most representative asbestos-related disease.The objectives of this study are to analyse the risk and protective factors associated with asbestos-related diseases and to investigate the incidence of new clinical manifestations in patients already diagnosed with some form of ARD. We have designed a matched case-control study with follow up of both cohorts from a population of a health district of the Barcelona province that has been exposed to asbestos for a period of 90 years. A better understanding of asbestos-related diseases should improve i) the clinical and epidemiological follow up of patients with this condition; ii) the design of new treatment strategies; iii) and the development of preventive activities. At the end of the study, the two cohorts created in this study (affected cases and healthy controls) will constitute the basis for future research.

ISS014-E-10547 (30 Dec. 2006) --- Barcelona, Spain is featured in this image photographed by an Expedition 14 crewmember on the International Space Station. Barcelona occupies a low plateau along the Mediterranean coastal plain. The city is the second largest in Spain (after the capital of Madrid), and hosts the country's largest seaport (portions of which are visible at lower right). This detailed view captures several notable features of the Barcelona urban landscape. The architectural design of the Eixample district (center) displays a grid pattern distinctive for Barcelona. Built during the 19th and 20th centuries, the district was built with octagonal city blocks -- originally intended to be open structures of only two or three sides surrounding gardens and open space. While the original street grid pattern remains, today many of the octagonal blocks are completely built up. The adjacent Cuitat Vella, or old city, presents a much denser building pattern which dates from Roman times. Also visible at lower right is the 173-meter high Montjuic Mountain -- historically the location of fortresses due to its strategic position overlooking the city's harbor. Light tan and orange structures visible at the crest of the mountain include the stadium and other buildings used in the 1992 Summer Olympic Games at Barcelona.

Intravenous artesunate has replaced quinine as the first-line therapy for severe imported malaria, given its anti-malarial superiority shown in clinical trials conducted in endemic countries. Evidence for red blood cell (RBC) exchange in patients with severe malaria treated with artesunate is lacking. This retrospective cohort study describes the experience at Hospital Clinic of Barcelona with the use of artesunate for severe malaria and the joint use of RBC exchange in selected cases. Patients treated for severe malaria at Hospital Clinic of Barcelona between August 2013 and January 2015 were included in this retrospective study. Severe malaria was defined according to WHO criteria. Data were extracted from electronic hospital records. A log-linear mixed model approach was used to estimate parasite clearance times. Within the study period, 42 patients were diagnosed of malaria at this centre, of which 38 had Plasmodium falciparum (90.5 %). Sixteen patients (42 %) had severe malaria cases and were treated with intravenous artesunate. Four patients underwent RBC exchange within a period of 15 h after the first dose of artesunate (range 9-21 h). The procedure lasted a median of 2 h (IQR 1.8-2 h), using a median of 12 (IQR 11-14) units of packed RBCs to replace a median of 3794 ml (IQR 2977-4343). The technique was well-tolerated without haemodynamic complications. There were no deaths. The regression model showed an estimated time to 95 % decay of 21.6 h (95 % CI 17.3-28.8). When assessing effect modification by RBC exchange, there was no difference in the parasite elimination rate (p = 0.286). In this study RBC exchange failed to show benefits in terms of parasite clearance probably due to the small number of patients analysed. The evidence for exchange transfusion remains limited.

Biochemical criteria at 1 year are not robust indicators of response to ursodeoxycholic acid in early primary biliary cirrhosis: results from a 29-year cohort study

Background In primary biliary cirrhosis (PBC), biochemical criteria at 1 year are considered surrogates of response to ursodeoxycholic acid (UDCA). However, due to the slow natural history of PBC, evaluation at 1 year may be suboptimal to assess the therapeutic response, particularly in early disease. Aim To determine whether evaluation of biochemical criteria at 1 year is a reliable surrogate of UDCA response in early PBC. Methods We analysed the prospectively collected data of 215 patients (untreated = 129; UDCA-treated = 86) with early PBC (normal baseline bilirubin/albumin) and a median follow-up of 8 years (range: 1–29.1). The 1-year attainment rates of the Barcelona, Paris-I, Paris-II and Toronto definitions, and their predictive relevance for a poor outcome (death, transplantation, complications of cirrhosis), were assessed either as a result of UDCA or no treatment. Independent associations with attaining each UDCA response definition were identified by multivariate analysis. Results Untreated patients displayed 1-year biochemical features compatible with ‘treatment response’ at rates (Barcelona: 36.4%, Paris-I: 66.7%, Toronto: 59.7%, Paris-II: 40.3%) similar to those obtained under UDCA. Depending on the definition, baseline ALP≤3xULN (OR: 4.80–35.90), AST≤2xULN (OR: 5.63–9.34) and early histological stage (OR: 3.67–3.87) were the stronger predictors for attaining the criteria. UDCA treatment was associated with attaining Barcelona (OR = 2.16) and Paris-II (OR = 2.84), but not Paris-I, and not Toronto definition when excluding late histological cases. Paris-I criteria were significantly predictive of long-term outcomes (HR = 2.83) in untreated patients. Conclusions In early PBC, biochemical criteria at 1 year reflect severity of the disease rather than the therapeutic response to UDCA. PMID:24117847

We conducted population-based surveillance for Candida bloodstream infections in Spain to determine its incidence, the extent of antifungal resistance, and risk factors for mortality. A case was defined as the first positive blood culture for any Candida spp. in a resident of Barcelona, from 1 January 2002 to 31 December 2003. We defined early mortality as occurring between days 3 to 7 after candidemia and late mortality as occurring between days 8 to 30. We detected 345 cases of candidemia, for an average annual incidence of 4.3 cases/100,000 population, 0.53 cases/1,000 hospital discharges, and 0.73 cases/10,000 patient-days. Outpatients comprised 11% of the cases, and 89% had a central venous catheter (CVC) at diagnosis. Overall mortality was 44%. Candida albicans was the most frequent species (51% of cases), followed by Candida parapsilosis (23%), Candida tropicalis (10%), Candida glabrata (8%), Candida krusei (4%), and other species (3%). Twenty-four isolates (7%) had decreased susceptibility to fluconazole (MIC ≥ 16 μg/ml). On multivariable analysis, early death was independently associated with hematological malignancy (odds ratio [OR], 3.5; 95% confidence interval [CI], 1.1 to 10.4). Treatment with antifungals (OR, 0.05; 95% CI, 0.01 to 0.2) and removal of CVCs (OR, 0.3; 95% CI, 0.1 to 0.9) were protective factors for early death. Receiving adequate treatment, defined as having CVCs removed and administration of an antifungal medication (OR, 0.2; 95% CI, 0.08 to 0.8), was associated with lower odds of late mortality; intubation (OR, 7.5; 95% CI, 2.6 to 21.1) was associated with higher odds. The incidence of candidemia and prevalence of fluconazole resistance are similar to other European countries, indicating that routine antifungal susceptibility testing is not warranted. Antifungal medication and catheter removal are critical in preventing mortality. PMID:15815004

Receiving adequate treatment, defined as having CVCs removed and administration of an antifungal medication (OR, 0.2; 95% CI, 0.08 to 0.8), was associated with lower odds of late mortality; intubation (OR, 7.5; 95% CI, 2.6 to 21.1) was associated with higher odds. The incidence of candidemia and prevalence of fluconazole resistance are similar to other European countries, indicating that routine antifungal susceptibility testing is not warranted. Antifungal medication and catheter removal are critical in preventing mortality.

A case-control study of dietary factors and gastric cancer was conducted between September 1986 and March 1989 in the Barcelona metropolitan area, Spain. In all 117 cases with histologically confirmed diagnosis of gastric adenocarcinoma were matched on sex, age and possession of a telephone to 234 population controls. Of the controls 188 (80.3%) were selected by random digit telephone dialing and 46 (19.7%) by neighbourhood of residence. Information about frequency and amount of consumption of 89 alimentary items was gathered by questionnaire, and cases and controls were interviewed in their homes by trained interviewers. The gastric cancer risk decreased in proportion to vitamin C intake. In multivariate analysis adjusting for major covariables, energy and vitamin A intake, the estimated odds ratio (OR) for the upper quartile of vitamin C intake was 0.3 (95% confidence interval [CI]: 0.1-0.8). After adjustment for major covariables, calories and vitamin C intake, vitamin A did not show significant association with the gastric cancer risk. Our findings are consistent with previous case-control studies and with the hypothesis that vitamin C may inhibit the intragastric nitrosation process.

2018-01-01

The aim of this study is the application of a software tool to the design of stripping columns to calculate the removal of trihalomethanes (THMs) from drinking water. The tool also allows calculating the rough capital cost of the column and the decrease in carcinogenic risk indeces associated with the elimination of THMs and, thus, the investment to save a human life. The design of stripping columns includes the determination, among other factors, of the height (HOG), the theoretical number of plates (NOG), and the section (S) of the columns based on the study of pressure drop. These results have been compared with THM stripping literature values, showing that simulation is sufficiently conservative. Three case studies were chosen to apply the developed software. The first case study was representative of small-scale application to a community in Córdoba (Spain) where chloroform is predominant and has a low concentration. The second case study was of an intermediate scale in a region in Venezuela, and the third case study was representative of large-scale treatment of water in the Barcelona metropolitan region (Spain). Results showed that case studies with larger scale and higher initial risk offer the best capital investment to decrease the risk. PMID:29562670

The presentation is directed to the description of the actual geodetic infrastructure of Barcelona harbour with three tide gauges of different technologies for sea level determination and contribution to regional sea level rise and understanding past and present sea level rise in the Barcelona harbour. It is intended that the overall system will constitute a CGPS Station of the ESEAS (European Sea Level) and TIGA (GPS Tide Gauge Benchmark Monitoring) networks. At Barcelona harbour there is a MIROS radar tide gauge belonging to Puertos del Estado (Spanish Harbours).The radar sensor is over the water surface, on a L-shaped structure which elevates it a few meters above the quay shelf. 1-min data are transmitted to the ENAGAS Control Center by cable and then sent each 1 min to Puertos del Estado by e-mail. The information includes wave forescast (mean period, significant wave height, sea level, etc.This sensor also measures agitation and sends wave parameters each 20 min. There is a GPS station Leica Geosystems GRX1200 GG Pro and antenna AX 1202 GG. The Control Tower of the Port of Barcelona is situated in the North dike of the so-called Energy Pier in the Barcelona harbor (Spain). This tower has different kind of antennas for navigation monitoring and a GNSS permanent station. As the tower is founded in reclaimed land, and because its metallic structure, the 50 m building is subjected to diverse movements, including periodic fluctuations due to temperature changes. In this contribution the 2009, 2011, 2012, 2013 and 2014 the necessary monitoring campaigns are described. In the framework of a Spanish Space Project, the instrumentation of sea level measurements has been improved by providing the Barcelona site with a radar tide gauge Datamar 2000C from Geonica S.L. in June 2014 near an acoustic tide gauge from the Barcelona Harbour installed in 2013. Precision levelling has been made several times in the last two years because the tower is founded in reclaimed land and a little far away from the geographic location of the pulse and acustic radar location on the Europa bridge. The measured settlement rate is about 1cm/year that may be could mask the values registered by the tide gauge. An intercomparison of the results of the three different tide gauges is presented and discussed. These activities has been received funding of the Ministerio de Ciencia e Innovacion under Spanish National Project CGL2009-13435/CLI.

The origin of the geothermal anomaly identified in the Barcelona underground (Spain): Future perspectives of this urban geothermal resource

During the drilling of line 9 of the Barcelona underground (Spain), a geothermal anomaly was detected, in which groundwater temperature was found to be up to 50°C. Previously, during the construction of the Fondo station in Santa Coloma de Gramanet (SCG), temperatures up to 37°C were already detected in this area. To study the feasibility of a future energy exploitation of the geothermal anomaly, a local and regional study is being undertaken. We present the first results of the new study. The objectives of this study were (1) to understand the flux regime of the hydrothermal system on both, local and large scale, (2) to explain the origin of the identified geothermal anomaly in SCG, and (3) to know the quality of the geothermal potential of the underground resources. To achieve these goals, different numerical models of groundwater flow and heat transport were performed. The area of study is constituted mainly of low permeability Palaeozoic granodiorites strongly weathered towards the top (lehm). These materials are affected by two sets of faults: the first one consists of porphyrýs dikes with a SW-NE direction and the second fault family which presents a NW-SE direction (Vázquez-Suñé et al., 2016). In the southeast area, the Quaternary deposits of the Besós River delta overlap these Palaeozoic materials. In spite of being a regional model, all these geological features have been incorporated in a complex mesh with more than 2.5 million finite elements. The results obtained suggest that in the case of SCG, the thermal anomaly found on the surface would have its origin in the rapid ascent of the hot water through these fracturing planes. Understanding the hydrogeothermal operation of the SCG system in detail and its possible temporal evolution will be of great interest for future evaluation, monitoring and management of the geothermal resources found, as well as to understand the interaction of these systems with urban infrastructures.

2008-01-01

Background The recent increase in the number of immigrants of Barcelona represents a challenge for the public healthcare system, the emergency department being the most used healthcare service by this group. However, utilisation rates in our environment have not yet been studied. We aimed to compare emergency department utilisation rates between Spanish-born and foreign-born residents in a public hospital of Barcelona. Methods The study population included all adults residing in the area of study and visiting the emergency department of Hospital del Mar in 2004. The emergency care episodes were selected from the Emergency Department register, and the population figures from the Statistics Department of Barcelona. Emergency care episodes were classified into five large clinical categories. Adjusted rate ratios (RR) of utilisation among foreign-born vs. Spanish-born residents were assessed through negative binomial regression. Results The overall utilisation rate was 382 emergency contacts per 1,000 persons-years. The RR for foreign-born versus Spanish-born residents was 0.62 (95% CI: 0.52; 0.74%). The RR was also significantly below one in surgery (0.51, 95% CI: 0.42; 0.63), traumatology (0.47, 95% CI: 0.38; 0.59), medicine (0.48, 95% CI: 0.38; 0.59) and psychiatry (0.42, 95% CI: 0.18; 0.97). No differences were found in utilisation of gynaecology and minor emergency services. Conclusion The overall lower utilisation rates obtained for foreign-born residents is consistent with previous studies and is probably due to the "healthy immigrant effect". Thus, the population increase due to immigration does not translate directly into a corresponding increase in the number of emergency contacts. The lack of differences in minor and gynaecological emergency care supports the hypothesis that immigrants overcome certain barriers by using the emergency department to access to health services. The issue of healthcare barriers should therefore be addressed, especially among immigrants. PMID:18315871

Synoptic analysis of heat waves in the Barcelona city (Catalonia, Spain) during 21st century

2017-04-01

The impact of extremely warm episodes on health has been analysed by a large number of studies conducted in different countries and cities, showing that heat waves events (HWE) can cause an abrupt increase in mortality. A HWE was defined as a 7-day sequence following a key-day labelled by the 95th percentile of Barcelona daily mortality (see Peña et al., 2015). The aim of this study is to identify synoptic patterns associated to HWE in Barcelona over the 21st century and evaluate the impact and possible mitigations. To achieve it, a multivariate analysis (MVA) integrating different atmospheric levels (sea level pressure, temperature at 850 hPa and geopotential at 500 hPa) was undertaken. The observed data used for this study was the 20th Century Reanalysis. The Max Planck Institute Earth system model was used to study two scenarios (RCP 4.5 and RCP 8.5) during the 21st century. The model was calibrated given the variability in the climate scenario, using the Quantile-Quantile mapping transformation (Q-Q). The MVA applied to the observed period (1990-2015) distinguish three main synoptic patterns: two dynamic configurations produced by southern fluxes related to an Atlantic low, associated with HWE recorded in southern Europe, and a third pattern identified by a stagnation situation related to persistent anticyclone periods. These patterns were also detected in the control simulated period (1961-2005) after the Q-Q calibration, preserving, therefore, the climatic variability: the number of HWE during the warm period (1990-2005) is twice more than during the cold period (1976-1989) due to an intensification of the warm masses. In the RCP 4.5 scenario (2006-2100 period) a positive and significant trend is shown in synoptic patterns which provoke HWE in Barcelona, especially during August; in the RCP 8.5 scenario there is no significant trend, but the intensification of the warm masses is higher.

At an intermediate or advanced stage, i.e. stage B or C, based on the Barcelona Clinic Liver Cancer classification of hepatocellular carcinoma (HCC), transarterial chemoembolization (TACE) may be offered as a treatment of palliative intent. We report the case of a patient suffering from acute respiratory distress syndrome after TACE with drug-eluting beads loaded with doxorubicin for HCC. To our knowledge, this is the first case described where a bronchoalveolar lavage was performed, and where significant levels of alveolar eosinophilia and neutrophilia were evident, attributed to a pulmonary toxicity of doxorubicin following liver chemoembolization. © 2014 S.

Vázquez de Quevedo, Francisco

2003-01-01

Two eminent Spanish surgeons from the positivism period were born 150 years ago: Ribera Sans and Salvador Cardenal. To mark this anniversary I have studied their written work and their contribution to Spanish surgery as pioneers. Each school had its own place although they kept certain parallelism. Ribera worked in Madrid as a professor for 23 years and had many disciples. He initiated digestive, pediatric and thoracic surgery. He was a professor at San Carlos just like the surgeons: San Martín and Guedea. He was director of the Niño Jesús Hospital and a R. A. N. M. academic. Cardenal is a distinguished surgeon who carried out his work in Barcelona. He extended the use of the antiseptic method in Spanish surgery. He became Director of the Sagrado Corazón Hospital. He was also named Honorary professor of surgery and a member of the Royal School of Surgery in England, and R. A. Barcelona. His work was closely related to Dr. Ferrán's. His son was León Cardenal.

Substance use among medical students in Barcelona (Spain). A comparison with previous surveys.

During the academic year 1983-1984, a survey on drug consumption was conducted among medical students in Barcelona. There was a high proportion of smokers in both sexes. Alcohol consumption was four times higher among men than women; high proof beverages were becoming the most common drinks. Coffee was the caffeine drink consumed by almost the whole population studied. Although cannabis derivatives had been tried at least once by almost all the students, regular consumers were almost non-existent. Amphetamine consumption was restricted to examination periods. The use of opiates, cocaine, hallucinogens, and solvents was rare for the sample. Results from this study are compared with those from similar surveys conducted 5 and 10 years ago.

Test Barcelona. Bilingüismo catalán-castellano. Adaptación lingüística de instrumentos neuropsicológicos. The present paper develops the Catalan version of the language subtests of the Barcelona Test (Peña-Casanova,1986) the original version of which was published in Spanish. To reach the Catalan version of the test it has been necessary to analyse the psycholinguistic variables of every item to then establish linguistically equivalent correlations. There are some subtests for which no modifications have been needed. Nevertheless, and because of some psycholinguistic features of Catalan (Catalan's spelling is not completely free of ambiguity) some subtests have suffered substantial modifications. The following paper presents the justification of every modification based on the features of the Catalan language and also based on the original goals of the test. An appendix contains the final version of the Catalan adaptation for the language subtests of the Barcelona Test. The present paper represents an advance in the assessment of neurological patients with language disfunctions. It will permit an appropiate assessment for the Spanish-Catalan bilingual patients.

Vitamin D deficiency is an important problem in patients with chronic conditions including those with human immunodeficiency virus (HIV) infection. The aim of this cross-sectional study was to identify the prevalence and factors associated with vitamin D deficiency and hyperparathyroidism in HIV patients attended in Barcelona. Cholecalciferol (25OH vitamin D3) and PTH levels were measured. Vitamin D insufficiency was defined as 25(OH) D < 20 ng/mL and deficiency as <12 ng/mL. Hyperparathyroidism was defined as PTH levels >65 pg/mL. Cases with chronic kidney failure, liver disease, treatments or conditions potentially affecting bone metabolism were excluded. Among the 566 patients included, 56.4% were exposed to tenofovir. Vitamin D insufficiency was found in 71.2% and 39.6% of those had deficiency. PTH was measured in 228 subjects, and 86 of them (37.7%) showed high levels. Adjusted predictors of vitamin D deficiency were nonwhite race and psychiatric comorbidity, while lipoatrophy was a protective factor. Independent risk factors of hyperparathyroidism were vitamin D < 12 ng/mL (OR: 2.14, CI 95%: 1.19-3.82, P: 0.01) and tenofovir exposure (OR: 3.55, CI 95%: 1.62-7.7, P: 0.002). High prevalence of vitamin deficiency and hyperparathyroidism was found in an area with high annual solar exposure.

The available evidence of the effects of air pollution and noise on behavioral development is limited, and it overlooks exposure at schools, where children spend a considerable amount of time. We aimed to investigate the associations of exposure to traffic-related air pollutants (TRAPs) and noise at school on behavioral development of schoolchildren. We evaluated children 7-11 years of age in Barcelona (Catalonia, Spain) during 2012-2013 within the BREATHE project. Indoor and outdoor concentrations of elemental carbon (EC), black carbon (BC), and nitrogen dioxide (NO2) were measured at schools in two separate 1-week campaigns. In one campaign we also measured noise levels inside classrooms. Parents filled out the strengths and difficulties questionnaire (SDQ) to assess child behavioral development, while teachers completed the attention deficit/hyperactivity disorder criteria of the DSM-IV (ADHD-DSM-IV) list to assess specific ADHD symptomatology. Negative binomial mixed-effects models were used to estimate associations between the exposures and behavioral development scores. Interquartile range (IQR) increases in indoor and outdoor EC, BC, and NO2 concentrations were positively associated with SDQ total difficulties scores (suggesting more frequent behavioral problems) in adjusted multivariate models, whereas noise was significantly associated with ADHD-DSM-IV scores. In our study population of 7- to 11-year-old children residing in Barcelona, exposure to TRAPs at school was associated with increased behavioral problems in schoolchildren. Noise exposure at school was associated with more ADHD symptoms.

Inequalities between immigrant and native populations in terms of access and use of health services have been described. The objective is to compare knowledge, attitudes, vulnerabilities, benefits and barriers related to breast cancer (BC) and screening mammography among women from different countries resident in Barcelona. A cross-sectional survey carried out in Barcelona in 2009. The study population consisted of female residents in Barcelona between 45 and 69 years of age; participants were Spanish nationals or immigrants from low-income countries. 960 participants were asked 72 questions, mainly with Likert responses. The dependent variables were five quantitative scales: (1) knowledge of BC and early detection, (2) attitude towards health and BC, (3) vulnerability to BC, (4) barriers to mammography, (5) benefits of mammography. The independent variables were country of origin, social class, setting, cohabitation, age, mammography use, length of residence and fluency of the language. Analyses compared scale scores stratified by the independent variables. Multivariable linear regression models were fitted to determine the relationship between the scales and the independent variables. We observed inequalities according to country of origin on all scales after adjustment for independent variables. Chinese women presented the greatest differences with respect to native women, followed by Maghrebi and Filipino women. Inequalities exist on the vulnerability and barriers scales according to social class and urban/rural setting, and on the attitude scale according to social class. Country of origin, social class and urban/rural setting are key contributors to inequality in these scales. Copyright © 2011 John Wiley & Sons, Ltd.

Poor mental health is a common problem in adolescence. Little information is available, however, about the factors influencing negative mood states in otherwise healthy adolescents. We aimed to describe the mood states and related factors in a sample of adolescents in the city of Barcelona (Spain). We administered a health survey to a sample of 2,727 students from public, subsidized, and private schools in Barcelona, aged approximately 14, 16, and 18 years old. To analyze the associations among moods and related factors, we used bivariate logistic regression, and fitted multivariate logistic regressions using the statistically significant variables from the bivariate analysis. To examine the possible group effects of the school on individual students, we employed multilevel analysis. The frequencies of negative mood states increased with age, with girls consistently reporting more frequent negative mood states than boys. The factors associated with negative mood states were problematic alcohol use, perceived mistreatment or abuse, antisocial behavior, intention to use or current use of illegal drugs (not including cannabis), lower perceived academic performance, and feeling isolated. Mood states are influenced by lifestyle and social factors, about which there is little local information. To plan and implement appropriate public health interventions, more complete information about the possible areas of influence is required. To complement the information obtained from studies such as the present study, longitudinal and qualitative studies would be desirable.

We report on different research and educational activities related to parabolic flights conducted in Barcelona since 2008. We use a CAP10B single-engine aerobatic aircraft flying out of Sabadell Airport and operating in visual flight conditions providing up to 8 seconds of hypogravity for each parabola. Aside from biomedical experiments being conducted, different student teams have flown in parabolic flights in the framework of the international contest `Barcelona Zero-G Challenge', and have published their results in relevant symposiums and scientific journals. The platform can certainly be a good testbed for a proof-of-concept before accessing other microgravity platforms, and has proved to be excellent for motivational student campaigns.

Prioritizing corresponds to the process of selecting and managing health needs identified after diagnosing the community's health needs and assets. Recently, the health needs assessment has been reinforced with the community perspective, providing multiple benefits: it sensitizes and empowers the community about their health, encourages mutual support among its members and promotes their importance by making them responsible for the process of improving their own reality. The objective of this paper is to describe the prioritization of Barcelona Salut als Barris, a community health strategy led by the Barcelona Public Health Agency to promote equity in health in the most disadvantaged neighborhoods of the city.

To study maternal and perinatal outcomes after physical examination-indicated cerclage in both singleton and twin pregnancies and evaluate the possible risk factors associated. Retrospective review of all women undergoing physical examination-indicated cerclage at the Hospital Vall d'Hebro, Barcelona from January 2009 to December 2012 after being diagnosed with cervical incompetence and risk of premature birth. During the study period, 60 cases of women diagnosed with cervical incompetence who were carrying live and morphologically-normal fetuses (53 singleton and 7 twin pregnancies), and who had an imminent risk of premature birth were evaluated. Mean gestational age until birth was 35 weeks in singleton and 32 weeks in twin pregnancies. Four cases (7.5%) of immature births and one case (2.0%) of neonatal death were recorded in singleton pregnancies. No cases of immature births or neonatal deaths were recorded in twin pregnancies. Diagnostic amniocentesis was performed IN all cases to rule out possible chorioamnionitis. Physical examination-indicated cerclage for cervical incompetence in women at risk for immature or preterm birth demonstrates good perinatal prognosis without increasing maternal morbidity in either singleton or twin pregnancies. The increase in gestation time in our study may also have been due to the fact that patients with subclinical chorioamnionitis were excluded by diagnostic amniocentesis.

Heavy rainfall episodes are relatively common in the conurbation of Barcelona and neighbouring cities (NE Spain), usually due to storms generated by convective phenomena in summer and eastern and south-eastern advections in autumn. Prevention of local flood episodes and right design of urban drainage have to take into account the rainfall intensity spread instead of a simple evaluation of daily rainfall amounts. The database comes from 5-min rain amounts recorded by tipping buckets in the Barcelona urban network along the years 1994-2009. From these data, extreme 5-min rain amounts are selected applying the peaks-over-threshold method for thresholds derived from both 95% percentile and the mean excess plot. The return period curves are derived from their statistical distribution for every gauge, describing with detail expected extreme 5-min rain amounts across the urban network. These curves are compared with those derived from annual extreme time series. In this way, areas in Barcelona submitted to different levels of flood risk from the point of view of rainfall intensity are detected. Additionally, global time trends on extreme 5-min rain amounts are quantified for the whole network and found as not statistically significant.

Particle structure, understood as the characterization of size, morphology, texture and the spatial distribution of the different compounds at an individual particle level, influences carbonaceous aggregates behavior in the atmosphere and the respiratory system. Additionally, the absorption and scattering of light is modified by the particle structure and also influences water absorption and water vapor nucleation and, hence cloud formation, residence time in the atmosphere and removal processes. Two factors seem determinant in these processes: quantity of scattering material adsorbed onto the light absorbing core during the residence in the atmosphere and subsequent aging, and the spatial distribution of this condensed matter (commonly discussed as internally/externally mixtures). Morning, noon, afternoon, and evening samples were collected for electron microscopy analyses during 3 consecutive days during an atmospheric episode of thermal inversion in February 2009 in an urban background area within the city of Barcelona. The main goal of this study was to quantify the variations in morphology and state of mixture of carbonaceous soot-like aggregate structures observed during different times of the day. The study was part of the winter campaign: "Determination of the sources of atmospheric Aerosols in Urban and Rural Environments in the western Mediterranean" (DAURE, February/March 2009). The analysis of the aggregate structure was conducted by digital image analysis of several thousand particles to determine variations on size, shape and texture by means of several different mathematical descriptors such as aspect ratio/elongation, compactness and roughness through fractal dimension analysis, textural energy and entropy. Results indicate that carbon aggregates were mostly within 200-400 nm of geometric size, with slightly smaller sizes during time intervals associated to traffic peaks compared to the daily average. The morphological parameters obtained for these ambient aggregates were compared with the same parameters obtained for carbon aggregates obtained from diesel exhaust and wood-burning combustion laboratory studies. Ambient carbon aggregates, independent of the time of the day, had very close values to those of freshly emitted from diesel combustion, with the exception of roughness and textural parameters. These differences were mainly associated to the properties of the coating (soot in internal mixture) presented in the urban carbon aggregates in comparison with the laboratory generated ones. No similarities were found with the carbon aggregates formed by the "tar balls" from wood-burning experiments. Results obtained to date show that freshly-emitted carbonaceous aggregates may become rapidly processed as found for Mexico City during the MILAGRO campaign (Johnson et al., 2005). In addition, carbonaceous aggregates in Barcelona presented similar sizes to internally mixed soot in Mexico City and the associated aspect ratios were also high indicating the tendency to maintain the fresh-structure (Adachi and Buseck, 2008). Whereas ambient soot particles were heavily internally mixed primarily with ammonium sulfate in the case of Mexico, low sulfate concentration was found in the Barcelona aggregates. The extraordinarily high concentration of nitrates and organic compounds during sampling together with the microscopy results suggests a complex coating structure comprised by mixtures of both nitrate and organic compounds. Further analyses are needed to understand more in detail the chemical nature and formation mechanisms of these coatings. References Adachi, K. and P.R.

Hepatocellular carcinoma (HCC)is the fifth most common malignancy associated with high mortality. One of the risk factors for HCC is chronic hepatitis B virus (HBV) infection. The treatment strategy for the disease is dependent on the stage of HCC, and the Barcelona clinic liver cancer (BCLC) staging system is used in most HCC cases. However, the molecular characteristics of HBV-related HCC in different BCLC stages are still unknown. Using GSE14520 microarray data from HBV-related HCC cases with BCLC stages from 0 (very early stage) to C (advanced stage) in the gene expression omnibus (GEO) database, differentially expressed genes (DEGs), including common DEGs and unique DEGs in different BCLC stages, were identified. These DEGs were located on different chromosomes. The molecular functions and biology pathways of DEGs were identified by gene ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, and the interactome networks of DEGs were constructed using the NetVenn online tool. The results revealed that both common DEGs and stage-specific DEGs were associated with various molecular functions and were involved in special biological pathways. In addition, several hub genes were found in the interactome networks of DEGs. The identified DEGs and hub genes promote our understanding of the molecular mechanisms underlying the development of HBV-related HCC through the different BCLC stages, and might be used as staging biomarkers or molecular targets for the treatment of HCC with HBV infection.

It has been suggested that certain residents, such as those with a low socioeconomic status, the elderly, and women, may benefit more from the presence of neighbourhood green space than others. We tested this hypothesis for age, gender, educational level, and employment status in four European cities. Data were collected in Barcelona (Spain; n = 1002), Kaunas (Lithuania; n = 989), Doetinchem (The Netherlands; n = 847), and Stoke-on-Trent (UK; n = 933) as part of the EU-funded PHENOTYPE project. Surveys were used to measure mental and general health, individual characteristics, and perceived neighbourhood green space. Additionally, we used audit data about neighbourhood green space. In Barcelona, there were positive associations between neighbourhood green space and general health among low-educated residents. In the other cities and for the other population groups, there was little evidence that the association between health and neighbourhood green space differed between population groups. Overall, our study does not support the assumption that the elderly, women, and residents who are not employed full-time benefit more from neighbourhood green space than others. Only in the highly urbanised city of Barcelona did the low-educated group benefit from neighbourhood green spaces. Perhaps neighbourhood green spaces are more important for the health of low-educated residents in particularly highly urbanised areas.

To assess the optimal cut-point for salivary cotinine concentration to identify smoking status in the adult population of Barcelona. We performed a cross-sectional study of a representative sample (n=1,117) of the adult population (>16 years) in Barcelona (2004-2005). This study gathered information on active and passive smoking by means of a questionnaire and a saliva sample for cotinine determination. We analyzed sensitivity and specificity according to sex, age, smoking status (daily and occasional), and exposure to second-hand smoke at home. ROC curves and the area under the curve were calculated. The prevalence of smokers (daily and occasional) was 27.8% (95% CI: 25.2-30.4%). The optimal cut-point to discriminate smoking status was 9.2 ng/ml (sensitivity=88.7% and specificity=89.0%). The area under the ROC curve was 0.952. The optimal cut-point was 12.2 ng/ml in men and 7.6 ng/ml in women. The optimal cut-point was higher at ages with a greater prevalence of smoking. Daily smokers had a higher cut-point than occasional smokers. The optimal cut-point to discriminate smoking status in the adult population is 9.2 ng/ml, with sensitivities and specificities around 90%. The cut-point was higher in men and in younger people. The cut-point increases with higher prevalence of daily smokers.

An increase in suicide mortality is often observed in economic recessions. The objective of this study was to analyse trends in socioeconomic inequalities in suicide mortality before and during the economic recession in two geographical settings in Spain. This study analyses inequalities in mortality according to educational level during 3 different time periods based on individual data from the Basque Country and Barcelona city. We analysed suicide mortality data for all residents over 25 years of age from 2001 to 2012. Two periods before the crisis (2001-2004 and 2005-2008) and another during the crisis (2009-2012) were studied. We performed independent analyses for sex, age group, and for the two geographical settings. We fit Poisson regression models to study the relationship between educational level and mortality, and calculated the relative index of inequality (RII) and the slope index of inequality (SII) as comparative measures. For men in the Basque Country, all RII values for the three time periods were similar and almost all were greater than 2; in Barcelona the RII values were generally lower. The SII values for Barcelona tended to decrease over time, whereas in the Basque Country they showed a U-shaped pattern. Among women aged 25-44 years we found an association between educational level and suicide mortality during the first time period; however, we found no clear association for other age groups or time periods. This study within two geographical settings in Spain shows that trends in inequalities in suicide mortality according to educational level remained stable among men before and during the economic recession.

There are few economic indicators that take the neighbourhood as the unit of reference in our context. The aim of this article is to describe the process and results of secondary data collection and development of a deprivation index (DI) for the neighbourhoods of the cities of Madrid and Barcelona, discussing their utility for research on health inequalities. Initial DI conceptual framework contained different elements that characterize deprivation and for which we collected second-level variables. ID was adapted to the availability of variables and to the results of an exploratory analysis. Finally, a factor analysis was performed to validate the IP. We built a DI based on five dimensions for Madrid (economy, population and territory, housing, cars and demographics) and 4 for Barcelona (all except "demographics"). Neighbourhoods were grouped into quartiles according to their score for the DI (Q4: higher levels of deprivation). Premature mortality rates and premature mortality ratios adjusted by age were calculated for each quartile. The IP explained 55% of the observed variability in the indicators for Madrid and 69% for Barcelona. Premature mortality rate in Madrid for Q1 was 1.65 per 10³ in men and 0.92 per 10³ women and 2.81 per 10³ in men and 1.22 per 10³ in women residing in Q4. In Barcelona, the mortality rate was 2.33 per 10³ men and 1.15 per 10³ women in Q1 and 3.49 per 10³ in men and 1.52 per 103 in women living in Q4. Premature mortality rates showed higher premature mortality in the most deprived districts.

Several epidemiological studies have reported associations between increases in summer temperatures and risks of premature mortality. The quantitative implications of predicted future increases in summer temperature, however, have not been extensively characterized. We have quantified these effects for the four main cities in Catalonia, Spain (Barcelona, Tarragona, Lleida, Girona). We first used case-crossover analysis to estimate the association between temperature and mortality for each of these cities for the period 1983 to 2006. These exposure-response (ER) functions were then combined with local measures of current and projected changes in population, mortality and temperature for the years 2025 and 2050. Predicted daily mean temperatures were based on the A1B greenhouse gas emission, "business-as-usual" scenario simulations derived from the ENSEMBLES project. Several different ER functions were examined and significant associations between temperature and mortality were observed for all four cities. For these four cities, the age-specific piecewise linear model predicts 520 (95%CI 340, 720) additional annual deaths attributable to the change in temperature in 2025 relative to the average from the baseline period of 1960-1990. For 2050, the estimate increases to 1,610 deaths per year during the warm season. For Catalonia as a whole, the point estimates for those two years are 720 and 2,330 deaths per year, respectively, or about 2 and 3% of the warm season. In comparing these predicted impacts with current causes of mortality, they clearly represent significant burdens to public health in Catalonia.

Pollen allergenicity plays an important role on human health and wellness. It is thus of large public interest to increase our knowledge of pollen grain behavior in the atmosphere (source, emission, processes involved during their transport, etc.) at fine temporal and spatial scales. First simulations with the Barcelona Supercomputing Center NMMB/BSC-CTM model of Platanus and Pinus dispersion in the atmosphere were performed during a 5-day pollination event observed in Barcelona, Spain, between 27 - 31 March, 2015. The simulations are compared to vertical profiles measured with the continuous Barcelona Micro Pulse Lidar system. First results show that the vertical distribution is well reproduced by the model in shape, but not in intensity, the model largely underestimating in the afternoon. Guidelines are proposed to improve the dispersion of airborne pollen by numerical prediction models.

The aim of the study is to classify the synoptic sequences associated with excess mortality during the warm season in the Barcelona metropolitan area. To achieve this purpose, we undertook a principal sequence pattern analysis that incorporates different atmospheric levels, in an attempt at identifying the main features that account for dynamic and thermodynamic atmospheric processes. The sequence length was determined by the short-term displacement between temperature and mortality. To detect this lag, we applied the cross-correlation function to the residuals obtained from the modelling of the daily temperature and mortality series of summer. These residuals were estimated by means of an autoregressive integrated moving average (ARIMA) model. A 7-day sequence emerged as the basic temporal unit for evaluating the synoptic background that triggers the temperature related to excess mortality in the Barcelona metropolitan area. The principal sequence pattern analysis distinguished three main synoptic patterns: two dynamic configurations produced by southern fluxes related to an Atlantic low, which can be associated with heat waves recorded in southern Europe, and a third pattern identified by a stagnation situation associated with the persistence of a blocking anticyclone over Europe, related to heat waves recorded in northern and central western Europe.

Large-artery intracranial atherosclerosis may be the most frequent cause of ischemic stroke worldwide. Traditional approaches have attempted to target the disease when it is already symptomatic. However, early detection of intracranial atherosclerosis may allow therapeutic intervention while the disease is still asymptomatic. The prevalence and natural history of asymptomatic intracranial atherosclerosis in Caucasians remain unclear. The aims of the Barcelona-ASymptomatic Intracranial Atherosclerosis (ASIA) study are (1) to determine the prevalence of ASIA in a moderate-high vascular risk population, (2) to study its prognostic impact on the risk of suffering future major ischemic events, and (3) to identify predictors of the development, progression and clinical expression of this condition. Cross-over and cohort, population-based study. A randomly selected representative sample of 1,503 subjects with a mild-moderate-high vascular risk (as defined by a REGICOR score ≥ 5%) and with neither a history of cerebrovascular nor ischemic heart disease will be studied. At baseline, all individuals will undergo extracranial and transcranial Color-Coded Duplex (TCCD) ultrasound examinations to detect presence and severity of extra and intracranial atherosclerosis. Intracranial stenoses will be assessed by magnetic resonance angiography (MRA). Clinical and demographic variables will be recorded and blood samples will be drawn to investigate clinical, biological and genetic factors associated with the presence of ASIA. A long-term clinical and sonographic follow-up will be conducted thereafter to identify predictors of disease progression and of incident vascular events. The Barcelona-ASIA is a population-based study aiming to evaluate the prevalence and clinical importance of asymptomatic intracranial large-artery atherosclerosis in Caucasians. The ASIA project may provide a unique scientific resource to better understand the dynamics of intracranial atherosclerosis from its early stages and to identify new potential therapeutic targets for this condition.

Vulnerability and seismic damage scenarios for Barcelona (Spain) by using GIS

2003-04-01

An integrated GIS-based analysis (using ArcView GIS) is performed in order to estimate damage scenarios for VI, VII and VIII EMS-98 seismic intensities in Barcelona (Spain). The analysis of vulnerability and damage of individual buildings is performed according to a simplified method developed by Giovanazzi and Lagomarsino at the University of Genoa (Italy). An index of average vulnerability is associated to each building typology, which may be refined on the basis of behaviour modifiers. The index allows identification of an analytical relationship between seismic input (intensity) and damage, described by a binomial distribution. This methodology, which is based on the EMS-98 building typologies and preserves the compatibility with preceding methods, is applied to the two main residential building typologies of Barcelona, that is, unreinforced masonry and reinforced concrete buildings. Then, the specific residential buildings of Barcelona are classified in different groups characterized by a similar seismic behaviour. Therefore, all buildings belonging to each typology are cast in the most probable class according to vulnerability. In this way, the average vulnerability index is associated to each building typology of Barcelona and it is refined later on the basis of behaviour modifiers, linked to the number of stories, the year of construction and their state of maintenance. The ability of GIS tools to store, manage, analyse, and display the large amount of spatial and tabular data involved in this study allows to map average vulnerability indexes, and damage for the entire city. That is, vulnerability and damage scenarios. The obtained results show a high vulnerability and high expected seismic damage. For a VI degree of intensity, the maximum expected damage is in the range 15-30 % in the oldest zones of the city, the downtown, while for intensity VII it is in the range 45-60%. The developed GIS tool involves a friendly interface that allows new models and database information to be included in the same framework. As a new step to the seismic risk assessment, and in addition to the building characteristics, the destination of the building, as well as the essential buildings, and the density of population for census zones, have been included in the GIS database. Combining this information with the previous damage maps we will be able to obtain more complete damage scenarios including, deaths, injuries, and homeless.

Floods are the most important natural hazard in the world. Nowadays, mitigation and adaptation strategies to reduce the impact that climate change will have on them, are a priority in most government agendas. Recent reports from the IPCC (2012, 2014) still show significant uncertainty associated with future projections of precipitation extremes. This uncertainty is higher when referred to floods and even larger when interactions with society and the changes in vulnerability are considered. Consequently, there is now a call to treat floods from a holistic perspective that integrates bottom-up (from impact and vulnerability) and top-down (from hazard) approaches (Hall et al., 2014). The study of flood risk in urban and peri-urban areas is complex and involves multiple factors. This is the case of the Metropolitan Area of Barcelona (AMB), which concentrates 43% of total population of Catalonia in less than 2% of the whole territory. The impervious soil has grown more than 200% from 1956 to 2009 (resulting in higher values of runoff), the population has increased more than 80% in the same period and, simultaneously, an improvement of the drainage system and flood prevention has been developed. As a result, we have seen that the flood risk evolution in the area holds a strong link to these human changes. Actually, floods in this region are usually due to drainage problems, flash floods in ungauged torrential catchments and, only in some occasions, river floods are produced (i.e. the Llobregat River on September 1971). But, in all the cases they are due to heavy precipitations. The main objective of the contribution is assessing the relationship between precipitation in the AMB and the social impacts produced. In order to do it, different impact indicators have been proposed, such as the population affected or the duration of the flood event (Merz et al., 2010). These indicators have been implemented for the different cases analyzed, which affected AMB for the period 1981-2015. These indicators have allowed developing a risk index based on the research of Amaro et al. (2010) and Barberia et al. (2014). Furthermore, the results are validated with damage information provided by the Insurance Compensation Consortium of Spain. The study also explores the evolution of land uses, population and precipitation from the middle of the 20th century until now, and how these changes have affected (or not) the flood risk in the AMB. This work has been developed in the framework of the Spanish project HOPE (CGL2014-52571-R) and METROBS study.

Intrinsic measures of field entropy in cosmological particle creation

NASA Astrophysics Data System (ADS)

Hu, B. L.; Pavon, D.

1986-11-01

Using the properties of quantum parametric oscillators, two quantities are identified which increase monotonically in time in the process of parametric amplification. The use of these quantities as possible measures of entropy generation in vacuum cosmological particle creation is suggested. These quantities which are of complementary nature are both related to the number of particles spontaneously created.

To determine the changes in Rheumatology provision and working practice that have occurred on the basis of the 1990, 1996 surveys carried out to update the Catalan Society for Rheumatology register The register includes all rheumatologists in Catalonia (Spain) who are registered and who do clinical work. Questionnaires were sent to all rheumatologists on the register. The questionnaires asked about location and clinical commitments. One hundred twenty-four rheumatologists work at the public system in Catalonia, 80 (65%) work at hospitals. The majority of rheumatologists (105; 84,6%) are located in the province of Barcelona. One fith of the rheumatologists have a temporal work. Ten general hospitals are still lacking of rheumatologists. Although the number of rheumatologists in Catalonia has increased there are ongoing inequalities in the provision of Rheumatology, especially between Barcelona and the rest of provinces.

To describe the actual presence of smoking in restaurant and hospitality premises after the smoking prevention act banning smoking in workplaces came into force in 2006, with wide exemptions in this sector. We performed an observational, descriptive study in Barcelona (Catalonia, Spain) in 2008 based on cluster sampling, with 1130 premises. The results were stratified by premise type. Up to 85.7% of food shops allowing consumption within their premises (bakeries, pastry shops...) ban smoking, as well as 85% of fast food establishments. Among restaurants, 40% are smoke-free or have separate smoking areas. Bar-cafés and café-restaurants (the most abundant premises) usually allow smoking. There are more smoke-free options in central districts and in shopping malls. Up to 75.4% of all premises allow smoking freely. These results show the limitations of the law. Copyright 2009 SESPAS.

To determine the characteristics of smear positive tuberculosis (TB) patients who generate secondary TB cases. Those smear positive TB patients detected by the Barcelona Tuberculosis Program between 1990-1993, and for whom contact studies had been performed, were studied. We analyzed the predictive role of the variables: age, sex, intravenous drug use (IVDU), the presence of the acquired immune deficiency syndrome (AIDS), human immunodeficiency virus (HIV) infection, radiology pattern, district of residence, history of imprisonment, alcoholism, smoking, history of TB, treatment compliance and the number of secondary cases generated. Statistical analysis was based on the logistic regression model, calculating the odds ratios (OR) with 95% confidence intervals (CI). Of the 1079 patients studied, 78 (7.2%) had generated only one secondary case, and 30 (2.8%) two or more. The variables associated with generating two or more secondary cases were: IVDU (P < 0.001; OR = 4.06; CI: 1.80-9.15), cavitary radiology pattern (P = 0.002; OR = 3.69; CI: 1.62-8.43), and age (P = 0.016; OR = 0.98; CI: 0.96-0.99). When we examined those who had generated one or more secondary cases, the following variables were significant: IVDU (P = 0.043; OR = 1.75; CI: 1.02-3.02), cavitary radiology pattern (P < 0.001; OR = 3.07; CI: 1.98-4.77) and age (P < 0.001; OR = 0.98; CI: 0.97-0.99). The study of the contacts of smear positive TB patients allows us to detect an important number of secondary cases. Young adults, those with cavitary radiology pattern, and IVDU are more likely to generate secondary cases.

From August 26th to 30th, the 2017 Annual Congress of the European Society of Cardiology (ESC 2017) was held in Barcelona, Spain. Despite the terrorism tradegy just before the ESC congress, the congress attracted many medical professionals from all over the world to discuss the recent topics in cardiovascular medicine in more than 500 sessions, including COMPASS (Cardiovascular OutcoMes for People using Anticoagulation StrategieS Trial), CANTOS (Canakinumab Anti-Inflammatory Thrombosis Outcomes Study), and ORION (which assessed the effect of a novel siRNA inhibitor to PCSK9 on reductions in low-density lipoprotein cholesterol). Japanese cardiologists and the Japanese Circulation Society greatly contributed to the congress. This report briefly introduces some late-breaking registry results, late-breaking clinical trials, and ESC Guidelines from the ESC 2017 Congress.

This study aims to describe trends in inequalities by women’s socioeconomic position and age in induced abortion in Barcelona (Spain) over 1992–1996 and 2000–2004. Induced abortions occurring in residents in Barcelona aged 20 and 44 years in the study period are included. Variables are age, educational level, and time periods. Induced abortion rates per 1,000 women and absolute differences for educational level, age, and time period are calculated. Poisson regression models are fitted to obtain the relative risk (RR) for trends. Induced abortion rates increased from 10.1 to 14.6 per 1,000 women aged 20–44 (RR = 1.44; 95% confidence interval (CI) 1.41–1.47) between 1992–1996 and 2000–2004. The abortion rate was highest among women aged 20–24 and 25–34 and changed little among women aged 35–44. Among women aged 20–24 and 25–34, those with a primary education or less had higher rates of induced abortion in the second period. Induced abortion rates also grew in those women with secondary education. In the 35–44 age group, the induced abortion rate declined among women with a secondary education (RR = 0.66; 95% CI 0.60–0.73) and slightly among those with a greater level of education. Induced abortion is rising most among women in poor socioeconomic positions. This study reveals deep inequalities in induced abortion in Barcelona, Spain. The trends identified in this study suggest that policy efforts to reduce unintended pregnancies are failing in Spain. Our study fills an important gap in literature on recent trends in Southern Europe. PMID:20229107

New treatment guidelines are required to improve the tuberculosis control strategies that have been used for 30 years. Seven centers of the Barcelona Tuberculosis Research Unit (BTRU) (Unitat d'Investigació en Tuberculosi de Barcelona) are collaborating with the Division of Tuberculosis Elimination of the United States Centers for Disease Control and Prevention in a series of clinical trials on latent tuberculosis infection and tuberculosis disease. BTRU participation began in 2004 with Study 26, an evaluation of the efficacy and tolerability of rifapentine plus isoniazid administered once weekly for 3 months compared with the standard treatment for latent tuberculosis infection. The BTRU centers together enrolled 246 patients (3% of the total). General enrollment was completed in February, 2008. HIV-infected patient and child enrollment continues. Treatment with 12 doses instead of 270 doses is expected to be a clear success. However, the analysis will be completed in 2010. Study 28 (started in 2006), designed for the treatment of pulmonary tuberculosis, compared standard treatment with an experimental regimen substituting moxifloxacin for isoniazid. BTRU centers together enrolled 15 patients (3.5% of the total). The provisional results (presented at the 47th Interscience Conference on Antimicrobial Agents and Chemotherapy in Chicago, 2007) showed no difference between the sputum conversion rate of each regimen at week 8 of treatment. Study 29 is currently underway, in which rifapentine was introduced in the experimental regimen for active tuberculosis treatment. Copyright (c) 2009 SESPAS. Published by Elsevier Espana.

In this study, we analyzed the clinical and molecular epidemiology of invasive serotype 5 (Ser5) pneumococcal isolates in four teaching hospitals in the Barcelona, Spain, area (from 1997 to 2011). Among 5,093 invasive pneumococcal isolates collected, 134 (2.6%) Ser5 isolates were detected. Although the overall incidence of Ser5-related invasive pneumococcal disease (IPD) was low (0.25 cases/100,000 inhabitants), three incidence peaks were detected: 0.63/100,000 in 1999, 1.15/100,000 in 2005, and 0.37/100,000 in 2009. The rates of Ser5 IPD were higher among young adults (18 to 64 years old) and older adults (>64 years old) in the first two peaks, whereas they were higher among children in 2009. The majority (88.8%) of the patients presented with pneumonia. Comorbid conditions were present in young adults (47.6%) and older adults (78.7%), the most common comorbid conditions being chronic obstructive pulmonary disease (20.6% and 38.3%, respectively) and cardiovascular diseases (11.1% and 38.3%, respectively). The mortality rates were higher among older adults (8.5%). All Ser5 pneumococci tested were fully susceptible to penicillin, cefotaxime, erythromycin, and ciprofloxacin. The resistance rates were 48.5% for co-trimoxazole, 6.7% for chloramphenicol, and 6% for tetracycline. Two major related sequence types (STs), ST1223 (n = 65) and ST289 (n = 61), were detected. The Colombia(5)-ST289 clone was responsible for all the cases in the Ser5 outbreak in 1999, whereas the ST1223 clone accounted for 73.8% and 61.5% of the isolates in 2005 and 2009, respectively. Ser5 pneumococci are a frequent cause of IPD outbreaks in the community and involve children and adults with or without comorbidities. The implementation of the new pneumococcal conjugated vaccines (PCV10 and PCV13) might prevent such outbreaks.

Weathering of gilding decorations investigated by SR: development and distribution of calcium oxalates in the case of Sant Benet de Bages (Barcelona, Spain)

In this paper seventeenth century gilded paintings from the crypt of Sant Benet de Bages, a medieval monastery in the Catalonia region of Spain, near Barcelona, have been studied. Cross sections from two different gilded decorations were studied by means of optical microscopy and electron microscopy and EDS to determine the statigraphy and elemental composition, and by means of FTIR coupled to a microscope to determine the binding media associated to each layer. These preliminary results demonstrated that gilded decorations were made by the application of a gold foil on a mordant substrate on a gypsum base, while the mouldings of the vaults seem to be gilded on a bol with a glaze on top of the gold leaf. It is interesting to notice that the first remained unaltered, while the gilded vault mouldings look almost black, due to the darkening of the organic material. To elucidate the causes involved in the darkening of the sample from the vaults a set of synchrotron μXRD and μFTIR experiments have been carried out on these samples at the ESRF (ID18F and ID21, respectively). High brightness and small spot working conditions revealed the development and distribution of calcium oxalates in the binding media, which seem to be responsible for the darkening. Results point out the fact that weddellite (CaC2O4·2H2O) is the phase formed in those layers where organic material has also been identified or at least it would be supposed to be by bibliographic sources and not necessarily those superficial as it would have been suggested due to the similarities with patinas formation.

The mobile colistin resistance gene mcr-1 has been identified worldwide in human and animal sources, while its occurrence in the environment is still largely unknown. The aim of this study was to investigate the presence of mcr-1 -harbouring Enterobacteriaceae in water samples obtained from rivers and waste water treatment plants in the area of Barcelona, Spain. The presence of mcr-1 was detected by PCR. Bacterial identification was performed via MALDI-TOF MS. Resistance to colistin was determined by a broth dilution method. The epidemiological relationship between the positive isolates was assessed with PFGE and ST was determined by MLST. Plasmid characterization was performed by transformation experiments, antimicrobial susceptibility testing and incompatibility group PCR. Thirty MDR isolates bearing mcr-1 , 29 Escherichia coli (ST632 and ST479) and 1 Klebsiella pneumoniae (ST526), were identified in sewage from two different waste water treatment plants, whereas the gene was not found in river water. All isolates, including the K. pneumoniae , harboured bla CTX-M-55 and bla TEM-1 . mcr-1 was in all cases associated with an IncI2 plasmid, which only conferred resistance to colistin. mcr-1 was harboured by two predominant E. coli clones that were found in both waste water treatment plants. This study showed a high occurrence of mcr-1 in the sewage of Barcelona, mainly due to the dissemination of two E. coli pulsotypes that are circulating in the population. The presence of mcr-1 in the environment is a cause for concern, and suggests high prevalence of mcr-1 in the community. © The Author 2017.

Everyday politics, social practices and movement networks: daily life in Barcelona's social centres.

PubMed

Yates, Luke

2015-06-01

The relations between everyday life and political participation are of interest for much contemporary social science. Yet studies of social movement protest still pay disproportionate attention to moments of mobilization, and to movements with clear organizational boundaries, tactics and goals. Exceptions have explored collective identity, 'free spaces' and prefigurative politics, but such processes are framed as important only in accounting for movements in abeyance, or in explaining movement persistence. This article focuses on the social practices taking place in and around social movement spaces, showing that political meanings, knowledge and alternative forms of social organization are continually being developed and cultivated. Social centres in Barcelona, Spain, autonomous political spaces hosting cultural and educational events, protest campaigns and alternative living arrangements, are used as empirical case studies. Daily practices of food provisioning, distributing space and dividing labour are politicized and politicizing as they unfold and develop over time and through diverse networks around social centres. Following Melucci, such latent processes set the conditions for social movements and mobilization to occur. However, they not only underpin mobilization, but are themselves politically expressive and prefigurative, with multiple layers of latency and visibility identifiable in performances of practices. The variety of political forms - adversarial, expressive, theoretical, and routinized everyday practices, allow diverse identities, materialities and meanings to overlap in movement spaces, and help explain networks of mutual support between loosely knit networks of activists and non-activists. An approach which focuses on practices and networks rather than mobilization and collective actors, it is argued, helps show how everyday life and political protest are mutually constitutive. © London School of Economics and Political Science 2014.

The overdevelopment of cities since the industrial revolution has shown the need to incorporate a sound geological knowledge in the management of required subsurface infrastructures and in the assessment of increasingly needed groundwater resources. Additionally, the scarcity of outcrops and the technical difficulty to conduct underground exploration in urban areas highlights the importance of implementing efficient management plans that deal with the legacy of heterogeneous subsurface information. To deal with these difficulties, a methodology has been proposed to integrate all the available spatio-temporal data into a comprehensive spatial database and a set of tools that facilitates the analysis and processing of the existing and newly added data for the city of Barcelona (NE Spain). Here we present the resulting actual subsurface 3-D geological model that incorporates and articulates all the information stored in the database. The methodology applied to Barcelona benefited from a good collaboration between administrative bodies and researchers that enabled the realization of a comprehensive geological database despite logistic difficulties. Currently, the public administration and also private sectors both benefit from the geological understanding acquired in the city of Barcelona, for example, when preparing the hydrogeological models used in groundwater assessment plans. The methodology further facilitates the continuous incorporation of new data in the implementation and sustainable management of urban groundwater, and also contributes to significantly reducing the costs of new infrastructures.

Tuberculous cold abscesses or gumma are an unusual form of tuberculosis. We report a case of gumma as initial diagnosis of disseminated tuberculosis. This case was studied in 2012 in Barcelona ( Spain). Source data was compiled from the electronic clinical records, hospital reports and additional diagnostic testing. Immunocompetent inmate, born in Cape Verde, living in Spain since the age of four. Positive tuberculin skin test. Initial examination without interest, but a palpable mass in lower back. Fine needle aspiration of the abscess was positive (PCR and Lowenstein) for M. tuberculosis. Computed tomography showed lung cavitary nodes in apical part and lung upper right side. After respiratory isolation, antituberculous therapy and an excellent evolution, the patient was discharged from hospital with disseminated tuberculosis diagnosis. It is advisable to monitor the injuries since, although rare, it may be secondary to Mycobacterium tuberculosis infection, mainly in inmuno-compromised populations and in immigrants coming from hyper-endemic tuberculosis areas.

In the last decade, the Neighbourhoods Law in Catalonia (Spain) funded municipalities that presented urban renewal projects within disadvantaged neighbourhoods focusing on physical, social and economic improvements. The objective of the study was to evaluate the effects of this law on the health and health inequalities of residents in the intervened neighbourhoods in the city of Barcelona. A quasi-experimental predesign and postdesign was used to compare adult residents in five intervened neighbourhoods with eight non-intervened comparison neighbourhoods with similar socioeconomic characteristics. The Barcelona Health Survey was used for studying self-rated and mental health in pre (2001, 2006) and post (2011) years. Poisson regression models stratified by sex were used to compute prevalence ratios comparing 2011 with 2006, and later stratified by social class, to study health inequalities. The intervened neighbourhoods had a significant decrease in poor self-rated health in both sexes while no significant changes occurred in the comparison group. When stratified by social class, a significant improvement was observed in poor self-rated health in the manual group of the intervened neighbourhoods in both sexes, resulting in a decrease in self-rated health inequalities. Similar results were observed in poor mental health of women, while in men, poor mental health worsens in both neighbourhood groups but mostly in the comparison group. The Neighbourhoods Law had a positive effect on self-rated health and seems to prevent poor mental health increases in both sexes and especially among manual social classes.

The potential impacts of electric vehicles on air quality in the urban areas of Barcelona and Madrid (Spain)

NASA Astrophysics Data System (ADS)

Soret, A.; Guevara, M.; Baldasano, J. M.

2014-12-01

This work analyses the potential air quality improvements resulting from three fleet electrification scenarios (∼13, 26 and 40%) by replacing conventional vehicles with Electric Battery Vehicles (EBVs), Plug-in Hybrid Electric Vehicles (PHEVs) and Hybrid Electric Vehicles (HEVs). This study has been performed for the cities of Barcelona and Madrid (Spain), where road transport is the primary emission source. In these urban areas, several air quality problems are present, mainly related to NO2 and particulate matter. The WRF-ARW/HERMESv2/CMAQ model system has been applied at high spatial (1 × 1 km2) and temporal (1 h) resolution. The results show that fleet electrification offers a potential for emission abatement, especially related to NOx and CO. Regarding the more ambitious scenario (∼40% fleet electrification), reductions of 11% and 17% of the total NOx emissions are observed in Barcelona and Madrid respectively. These emissions reductions involve air quality improvements in NO2 maximum hourly values up to 16%: reductions up to 30 and 35 μg m-3 in Barcelona and Madrid, respectively. Furthermore, an additional scenario has been defined considering electric generation emissions associated with EBVs and PHEVs charging from a combined-cycle power plant. These charging emissions would produce slight NO2 increases in the downwind areas of <3 μg m-3. Thus, fleet electrification would improve urban air quality even when considering emissions associated with charging electric vehicles. However, two further points should be considered. First, fleet electrification cannot be considered a unique solution, and other management strategies may be defined. This is especially important with respect to particulate matter emissions, which are not significantly reduced by fleet electrification (<5%) due to the high weight of non-exhaust emissions. Second, a significant introduction of electric vehicles (26-40%) involving all vehicle categories is required to improve urban air quality.

Origin of fine carbonaceous particulate matter in the Western Mediterranean Basin: fossil versus modern sources

The present work was carried out in the frame of the international field campaign DAURE (Determination of the sources of atmospheric Aerosols in Urban and Rural Environments in the western Mediterranean). The objective of this campaign is to study the aerosol pollution episodes occurring at regional scale during winter and summer in the Western Mediterranean Basin. As part of this campaign, this work focuses on identifying the origin of fine carbonaceous aerosols. To this end, fine particulate matter (PM1) samples were collected during two different seasons (February-March and July 2009) at two sites: an urban site (Barcelona, NE Spain) and a rural European Supersite for Atmospheric Aerosol Research (Montseny, NE Spain). Subsequently, 14C analyses were carried out on these samples, both in the elemental carbon (EC) fraction and the organic carbon (OC) fraction, in order to distinguish between modern carbonaceous sources (biogenic emissions and biomass burning emissions) and fossil carbonaceous sources (mainly road traffic). Preliminary results from the winter period show that 40% of the OC at Barcelona has a fossil origin whereas at Montseny this percentage is 30%. These values can be considered as unexpected given the nature of the sites. Nevertheless, the absolute concentrations of fossil OC at Barcelona and Montseny differ by a factor of 2 (the first being higher), since the total OC at Montseny is lower than at Barcelona. Further evaluation of results and comparison with other measurements carried out during the campaign are required to better evaluate the origin of the fine carbonaceous matter in the Western Mediterranean Basin.

Levelling VS. InSAR in Urban Underground Construction Monitoring. Case of la Sagrera Railway Station (barcelona, Spain).

Vázquez-Suñé, E.; Serrano-Juan, A.; Pujades, E.; Crosetto, M.

2016-12-01

Construction processes require monitoring to ensure safety and to control the new and existing structures. The most accurate and spread monitoring method to measure displacements is levelling, a point-like surveying technique that tipically allows for tens of discrete in-situ sub-millimetric measures per squared kilometer. Another emerging technique for mapping soil deformation is the Interferometric Synthetic Aperture Radar (InSAR), which is based on SAR images acquired from orbiting satellites. This remote sensing technique can provide better spatial point density than levelling, more extensive spatial coverage and cheaper acquisitions. This paper analyses, compares and discusses levelling and InSAR measurements when they are used to measure the soil deformation induced by the dewatering associated to underground constructions in urban areas. To do so, an experiment was performed in the future railway station of La Sagrera, Barcelona (Spain), in which levelling and InSAR were used to accurately quantify ground deformation by dewatering. Results showed that soil displacements measured by levelling and InSAR were not always consisting. InSAR measurements were more accurate with respect the soil deformation produced by the dewatering while levelling was really useful to determine the real impact of the construction on the nearby buildings.

Our previous imaging research performed as part of a Urea Cycle Rare Disorders Consortium (UCRDC) grant, has identified specific biomarkers of neurologic injury in ornithine transcarbamylase deficiency, OTCD. While characterization of mutations can be achieved in most cases, this information does not necessarily predict the severity of the underlying neurological syndrome. The biochemical consequences of any mutation may be modified additionally by a large number of factors, including contributions of other enzymes and transport systems that mediate flux through the urea cycle, diet and other environmental factors. These factors likely vary from one patient to another, and they give rise to heterogeneity of clinical severity. Affected cognitive domains include non-verbal learning, fine motor processing, reaction time, visual memory, attention, and executive function. Deficits in these capacities may be seen in symptomatic patients, as well as asymptomatic carriers with normal IQ and correlate with variances in brain structure and function in these patients. Using neuroimaging we can identify biomarkers that reflect the downstream impact of UCDs on cognition.

From an environmental perspective, the underground metro system is one of the cleanest forms of public transportation in urban agglomerations. Current studies report contradicting results regarding air quality in the metro systems: whereas some reveal poor air quality, others report PM levels which are lower or of the same order of magnitude than those measured in traffic sites above ground level. The present work assesses summer and winter indoor air quality and passenger exposure in the Barcelona metro, focusing on PM levels and their metal contents. In addition, the impact on indoor air quality of platform screen door systems (automated systems consisting of closed rail track and platforms) is evaluated, to determine whether these systems reduce passenger exposure to PM when compared with conventional systems (open tracks and platforms). In the Barcelona metro PM levels inside the trains in summer are amongst the lowest reported for worldwide metro systems (11-32 μg m-3 PM2.5). This is most likely due to the air conditioning system working in all carriages of the Barcelona metro during the whole year. Levels were considerably higher on the platforms, reaching mean levels of 46 and 125 μg m3 in the new (L9) and old (L3) lines, respectively. PM10 data are also reported in the present study, but comparison with other metro systems is difficult due to the scarcity of data compared with PM2.5. Results showed distinct PM daily cycles, with a drastic increase from 06:00 to 07:00 a.m., a diurnal maximum from 07:00 to 10:00 p.m., and marked decrease between 10:00 p.m. and 05:00 a.m. The elements with the highest enrichment were those associated with wheel or brake abrasion products (Ba, Fe, Cu, Mn, Cr, Sb, As, Mo, Co, Sr, among others). Laminar hematite (Fe2O3) was the dominant particle type, being mainly originated by mechanical abrasion of the rail track and wheels. Regarding passenger exposure to PM, the contribution of commuting by metro was estimated to account for around 10% of the daily exposure. However, this contribution may be one order of magnitude higher when specific matals are considered. Finally, we conclude that the implementation of platform screen door systems results in reductions of both PM levels and metal concentrations. In addition an advanced optimized ventilation system gave even a much higher efficiency in reducing exposure to PM of metro commuters. Combining these two features PM exposure levels in the platforms may be reduced down by a factor of 7 with respect the old subway lines in Barcelona.

Spatial and temporal variability of PM levels and composition in a complex summer atmospheric scenario in Barcelona (NE Spain)

Viana, M.; Pérez, C.; Querol, X.; Alastuey, A.; Nickovic, S.; Baldasano, J. M.

Summer atmospheric coastal dynamics exert a significant influence on the levels and composition of atmospheric particulate matter (PM) in the North-Eastern Iberian Peninsula. Summer atmospheric scenarios in this region present a high degree of complexity as they are characterised by the absence of synoptic-scale air mass advections, the development of breeze circulations, enhanced photochemistry, local mineral dust re-suspension and the occurrence of African dust outbreaks. Three sampling sites were selected in Barcelona (NE Spain), an urban coastal site surrounded by complex topography. Regional dust modelling (DREAM) and high resolution meteorological modelling (MM5) were used to interpret PM levels and composition at the three sites. The results outline the effect of breeze dynamics and thermal internal boundary layer formation as the main meteorological drivers of the hourly evolution of PM levels. Levels of crustal components, secondary inorganic and carbon species are higher during the night, and only the marine aerosol content is higher during the day. Nitrate levels are higher during the night due to the thermal stability on NH 4NO 3. Sulphate levels are higher during the night as a consequence of the drainage flows. Lidar measurements and model results signalled the occurrence of two African dust episodes during the study period which mainly affected the free troposphere over Barcelona.

To examine the effects of Neo-Marxian social class (i.e. measured as relations of control over productive assets) and potential mediators such as labour-market position, work organization, material deprivation and health behaviours upon mortality in Barcelona, Spain. Longitudinal data from the Barcelona 2000 Health Interview Survey (n = 7526) with follow-up interviews through the municipal census in 2008 (95.97% response rate) were used. Using data on relations of property, organizational power, and education, social classes were grouped according to Wright's scheme: capitalists, petit bourgeoisie, managers, supervisors, and skilled, semi-skilled and unskilled workers. Social class, measured as relations of control over productive assets, is an important predictor of mortality among working-class positions for men but not for women. Workers (hazard ratio 1.60, 95% confidence interval 1.10-2.35), managers and small employers had a higher risk of death than capitalists. The extensive use of conventional gradient measures of social stratification has neglected sociological measurements of social class conceptualized as relations of control over productive assets. This concept is capable of explaining how social inequalities are generated. To confirm the protective effect of the capitalist class position and the ''contradictory class location hypothesis'', additional efforts are needed to properly measure class among low-level supervisors, capitalists, managers, and small employers.

Maximum cross-correlation provides a method toremotely de-ter-mine high-lyre-solved three-dimensional fields of horizontalwinds with e-las-tic li-darthrough-out large volumes of the planetaryboundary layer (PBL). This paperdetails the technique and shows comparisonsbetween elastic lidar winds, remotelysensed laser Doppler velocimeter (LDV) windprofiles, and radiosonde winds.Radiosonde wind data were acquired at Barcelona,Spain, during the BarcelonaAir-Quality Initiative (1992), and the LDVwind data were acquired at SunlandPark, New Mexico during the 1994 Border AreaAir-Quality Study. Comparisonsshow good agreement between the differentinstruments, and demonstrate the methoduseful for air pollution management at thelocal/regional scale. Elastic lidar windscould thus offer insight into aerosol andpollution transport within the PBL. Lidarwind fields might also be used to nudge orimprove initialization and evaluation ofatmospheric meteorological models.

Immigration is a recent phenomenon in Spain. Certain subgroups of the immigrant population may be vulnerable to acquiring sexually transmitted infections (STI). Descriptive study of the seroprevalenceof certain STI (HIV, hepatitis B and syphilis) and the general characteristicsn of persons tested for HIV infection in a specialized clinic in Barcelona during the year 2000. Seroprevalence of HIV was similar in immigrants and native residents(1.8% vs. 1.7% respectively). However, the seroprevalences of hepatitis B virus (anti-HBc) (19.5% vs. 8.3%) and syphilis (RPR 1 TPHA) (3.2% vs. 1.1%), as well as other STI and the practice of prostitution, were higher in immigrants. Several STI, including hepatitis B and syphilis, were found more frequently in immigrants than in the native population, whereas HIV seroprevalence was similar in the two groups.

Sources and evolution of ultrafine particles were investigated both horizontally and vertically in the large urban agglomerate of Barcelona, Spain. Within the SAPUSS project (Solving Aerosol Problems by Using Synergistic Strategies), a large number of instruments was deployed simultaneously at different monitoring sites (road, two urban background, regional background, urban tower 150 m a.s.l., urban background tower site 80 m a.s.l.) during a 4 week period in September-October 2010. Particle number concentrations (N>5 nm) are highly correlated with black carbon (BC) at all sites only under strong vehicular traffic influences. By contrast, under cleaner atmospheric conditions (low condensation sink, CS) such correlation diverges towards much higher N/BC ratios at all sites, indicating additional sources of particles including secondary production of freshly nucleated particles. Size-resolved aerosol distributions (N10-500) as well as particle number concentrations (N>5 nm) allow us to identify three types of nucleation and growth events: (1) a regional type event originating in the whole study region and impacting almost simultaneously the urban city of Barcelona and the surrounding urban background area; (2) a regional type event impacting only the regional background area but not the urban agglomerate; (3) an urban type event which originates only within the city centre but whose growth continues while transported away from the city to the regional background. Furthermore, during these clean air days, higher N are found at tower level than at ground level only in the city centre whereas such a difference is not so pronounced at the remote urban background tower. In other words, this study suggests that the column of air above the city ground level possesses the optimal combination between low CS and high vapour source, hence enhancing the concentrations of freshly nucleated particles. By contrast, within stagnant polluted atmospheric conditions, higher N and BC concentrations are always measured at ground level relative to tower level at all sites. Our study suggests that the city centre of Barcelona is a source of non-volatile traffic primary particles (29-39% of N>5 nm), but other sources, including secondary freshly nucleated particles contribute up to 61-71% of particle number (N>5 nm) at all sites. We suggest that organic compounds evaporating from freshly emitted traffic particles are a possible candidate for new particle formation within the city and urban plume.

In order to know about the health of the population, it is necessary to perform a systematic and continuous analysis of their health status and social and economic health determinants. The objective of this paper is to describe the development and implementation of the Infobarris tool, which allows to visualize a wide battery of indicators and social determinants of health by neighbourhoods in the city of Barcelona (Spain). For the development of the Infobarris tool, we used an agile methodology that allows the development of a project in iterative and incremental stages, which are the following: selection of indicators, design of the prototype, development of the tool, data loading, and tool review and improvements. Infobarris displays 64 indicators of health and its determinants through graphics, maps and tables, in a friendly, interactive and attractive way, which facilitates health surveillance in the neighbourhoods of Barcelona.

Wild boar populations are expanding throughout the world and intruding into periurban and urban areas. In the last years, wild boar has colonized several European cities, including our study area, the city of Barcelona. It is required to identify the main factors driving wild boar into urban areas prior to establish management measures. We built Boosted Regression Trees (BRT) using 3148 wild boar presences registered in the urban area of Barcelona from 2010 to 2014 to identify the variables correlated with these presences. The variables analysed included proxies for distance to source population, urban food resources, climate and urban habitat structure. Wild boars enter the urban area from close natural habitat using corridors such as streams, preferably in fragmented urban environment, looking for food such as urban green areas or dry pet food from cat colonies. Wild boar presence is higher in spring possibly due to the births of piglets and the dispersion of yearlings during that season, and also when natural resources in the Mediterranean habitat fail to satisfy the nutritional requirements of the wild boar population during the summer season. Management measures derived from this study are currently being applied in the city of Barcelona, including vegetation clearings in the wild boar entrance areas and an awareness campaign aimed at reducing the anthropogenic food availability for wild boars. The methodology used can be applied to other cities with wild boar or even other wildlife species issues. The comparison between the factors attracting wild boars into different urban areas would be helpful to understand the global phenomenon. Copyright © 2017 Elsevier B.V. All rights reserved.

The statistics related to labor accidents as with any other notification system ought to be the basis for programs and policies with a view to the adoption of preventive measures. In order to establish preventive norms, however, the health system needs data from researchers focussing on the dynamics of and the pitfalls revealed by specific events. Within this context the main objective of this study is to proceed with an in-depth analysis of the labor accidents verified in Barcelona (Spain) using for this purpose a descriptive statistics model to test variables such as type of accident, economic sector, economic enterprise and type of labor contract. The data source utilized was the notification system for labor accidents with grave consequences such as death of the victim registered in Barcelona during the period 1992-1993. Labor accidents registered for male workers numbered 848. A log-linear model was applied to this data base. The results show a positive association between traumatic accidents with the construction, traffic and services sectors. A positive association was also found between traumatic accidents and the size of the company concerved the small ones being the worse type in terms of worker's injuries. Regarding the nontraumatic accidents, the study showed a positive correlation between large-sized enterprises and type of temporary worker and the civil construction sector as compared to workers with long term work contracts within industry and services. There was some evidence, also, of a positive association between small and medium sized companies and temporary work and the occurrence of work accidents.

Childhood overweight and obesity have increased progressively in the last decades, especially in countries of Southern Europe. The aim of this study was to identify the prevalence of overweight, obesity and its determinants in schoolchildren between 8-9 years old from Barcelona. Cross-sectional study of a representative sample of 3,262 schoolchildren in 2011. Body Mass Index (BMI) was calculated following the criteria established by the World Health Organization (z-scores). Variables on eating behaviour, physical activity and use of new technologies were studied through 2 questionnaires. Logistic regression models were adjusted, obtaining adjusted odds ratio and their confidence intervals (95%). The prevalence of overweight was 24.0% and 12.7% for obesity. Obesity was significantly higher in boys than in girls (14.8% vs 10.8%.). No statistically significant differences were observed in the compliance of recommendations of physical activity practice and use of new technologies according to BMI. Factors associated with obesity in boys were to attend a school located in a neighbourhood of disadvantaged socio-economic status [ORa=1.88 (1.35-2.63)], to belong to an immigrant family [ORa=1.57 (1.12-2.20)], to do not eat at school [ORa=1.76 (1.20-2.59)] and to have some meal alone [ORa=1.95 (1.27-3.00)]. In girls associated factors were to belong to a single-parent family [ORa=1.58 (1.06-2.34)] and to an immigrant family [ORa=1.53 (1.07-2.18)]. The prevalence of childhood obesity in Barcelona is high. It is more common in boys, being the social determinants most relevant associated factors.

STUDY OBJECTIVE--To describe temporal and geographical variations in mortality from acute reactions to opiates or cocaine and the demographic and toxicological characteristics of persons who died from these in major Spanish cities between 1983 and 1991. DESIGN--Descriptive study. Data were obtained retrospectively from pathologists' reports. SETTING--Cities of Madrid, Barcelona, Valencia, Seville, Zaragoza, and Bilbao. SUBJECTS--Deaths from acute reactions to opiates or cocaine were defined as those in which pathologists' reports did not indicate any other cause of death and in which evidence was found of recent consumption of these drugs. MAIN RESULTS--The mortality rate from acute reactions to opiate/cocaine per 100,000 population in the six cities as a whole rose from 1.2 in 1983 to 8.2 in 1991. Average annual rates for the whole period ranged from 1.7 in Seville to 4.9 in Barcelona. The male/female rates ratio was 5.9:1. The mean age of persons who died rose from 25.1 years in 1983 to 28 years in 1991. In more than 90% of the cases in whom toxicological tests were undertaken opiates were detected, and the proportion in which benzodiazepines or cocaine were detected increased during the period studied. CONCLUSIONS--Between 1983 and 1991 mortality from acute reactions to opiates/cocaine rose dramatically in major Spanish cities and significant differences in mortality between cities were found. Deaths were concentrated among men and young people. Acute drug reactions became one of the leading causes of death in persons 15-39 years of age, representing 11.1% of mortality from all causes in 1988 for this age group. Future studies should examine the relationship between the temporal and geographical variations in this type of mortality and various personal, environmental and social factors. PMID:7707007

Malaria remains a major source of morbi-mortality among travellers. In 2007, a consensual multicenter Primary Care-Hospital shared guideline on travel-prior chemoprophylaxis, diagnosis and clinical management of imported malaria was set up in the Barcelona North Metropolitan area. The aim of the study is to assess the evolution of malaria cases in the area as well as its clinical management over the 10 years of its implementation. A total of 190 malaria cases, all them imported, have been recorded. The overall estimated malaria crude incidence was of 0.47 cases per 10,000 population/year (95% CI 0.34-0.59) with a slight significant positive slope especially at the expense of an increase in Indian sub-continent Plasmodium vivax cases. The number of patients who attended the pre-travel consultation was low (13.7%) as well as those with prescribed chemoprophylaxis (10%). Severe malaria was diagnosed in 34 (17.9%) patients and ICU admittance was required in 2.6% of them. Organ sequelae (two renal failures and one post-acute distress respiratory syndrome) were recorded in 3 patients at hospital discharge, although all three were recovered at 30 days. None of the patients died. Patients complying with severity criteria were significantly males (p = 0.04), came from Africa (p = 0.02), were mainly non-immigrant travellers (p = 0.01) and were attended in a hospital setting (p < 0.001). The most frequently identified species was Plasmodium falciparum (64.2%), P. vivax (23.2%), Plasmodium malariae (1.6%) and Plasmodium ovale (1.1%). Those patients diagnosed with P. falciparum malaria came more often from sub-Saharan Africa (p < 0.001) and those with P. vivax came largely from the Indian sub-continent (p = 0.003). Among the 126 patients in whom an immunochromatographic antigenic test was performed, the result was interpreted as falsely negative in 12.1% of them. False negative results can be related to cases with <1% parasitaemia. After 10 years of surveillance, a moderate increase in malaria incidence was observed, mostly P. vivax cases imported from the Indian sub-continent. Although severe malaria cases have been frequently reported, none of the patients died and organ sequelae were rare. Conceivably, the participation of the Primary Care and the District and Third Level Hospital professionals defining surveillance, diagnostic tests, referral criteria and clinical management can be considered a useful tool to minimize malaria morbi-mortality.

Being able to recruit high-risk volunteers who are also willing to consider future participation in vaccine trials are critical features of vaccine preparedness studies. We described data from two cohorts of injection- and non-injection drug users in Barcelona, Spain [Red Cross centre] and in San Francisco, USA, [UFO-VAX study] at high risk of HIV/HCV infection to assess behaviour risk exposure and willingness to participate in future preventive HIV vaccine trials. We successfully identified drug-using populations that would be eligible for future HIV vaccine efficacy trials, based on reported levels of risk during screening and high levels of willingness to participate. In both groups, Red Cross and UFO-VAX respectively, HCV infection was highly prevalent at baseline (41% and 34%), HIV baseline seroprevalence was 4.2% and 1.5%, and high levels of willingness were seen (83% and 78%).

Hepatocellular carcinoma (HCC) is a primary malignancy of the liver and occurs predominantly in apatient with underlying chronic liver disease and cirrhosis. HCC presented at an advancedstage with right-upper-quadrant pain, weight loss, and signs of decompensated liver disease; it is now increasingly recognized atmuch measurements of the biomarker. Some of them are Gamma-glutamyltranspeptidase to platelet ratio (GPR) and Albumin to Gamma- glutamyltranspeptidase (AGR). This study aimed to know the difference between GPR and AGR between degrees of the Barcelona Clinic Liver cancer (BCLC) on HCC patients. A retrospective study was carried out in 166 outpatient and inpatient HCC in Haji Adam Malik General Hospital from January 2015–December2016.Kruskal-Wallis test showed that there is no significant differentiation of GPR between degrees of BCLC (p=0.23), but there is a considerable differentiation of AGR between degrees of BCLC (p=0.032).

The population-based Barcelona-Asymptomatic Intracranial Atherosclerosis Study (ASIA): rationale and design

PubMed Central

2011-01-01

Background Large-artery intracranial atherosclerosis may be the most frequent cause of ischemic stroke worldwide. Traditional approaches have attempted to target the disease when it is already symptomatic. However, early detection of intracranial atherosclerosis may allow therapeutic intervention while the disease is still asymptomatic. The prevalence and natural history of asymptomatic intracranial atherosclerosis in Caucasians remain unclear. The aims of the Barcelona-ASymptomatic Intracranial Atherosclerosis (ASIA) study are (1) to determine the prevalence of ASIA in a moderate-high vascular risk population, (2) to study its prognostic impact on the risk of suffering future major ischemic events, and (3) to identify predictors of the development, progression and clinical expression of this condition. Methods/Design Cross-over and cohort, population-based study. A randomly selected representative sample of 1,503 subjects with a mild-moderate-high vascular risk (as defined by a REGICOR score ≥ 5%) and with neither a history of cerebrovascular nor ischemic heart disease will be studied. At baseline, all individuals will undergo extracranial and transcranial Color-Coded Duplex (TCCD) ultrasound examinations to detect presence and severity of extra and intracranial atherosclerosis. Intracranial stenoses will be assessed by magnetic resonance angiography (MRA). Clinical and demographic variables will be recorded and blood samples will be drawn to investigate clinical, biological and genetic factors associated with the presence of ASIA. A long-term clinical and sonographic follow-up will be conducted thereafter to identify predictors of disease progression and of incident vascular events. Discussion The Barcelona-ASIA is a population-based study aiming to evaluate the prevalence and clinical importance of asymptomatic intracranial large-artery atherosclerosis in Caucasians. The ASIA project may provide a unique scientific resource to better understand the dynamics of intracranial atherosclerosis from its early stages and to identify new potential therapeutic targets for this condition.

Construction and preliminary validation of the Barcelona Immigration Stress Scale.

In the study of mental health and migration, an increasing number of researchers have shifted the focus away from the concept of acculturation towards the stress present in the migratory experience. The bulk of research on acculturative stress has been carried out in the United States, and thus the definition and measurement of the construct has been predicated on that cultural and demographic context, which is of dubious applicability in Europe in general, and Spain in particular. Further, some scales have focused on international students, which down-played the importance of the migratory process, because it deals with a special subset of people who are not formally immigrating. The Barcelona Immigration Stress Scale was developed to measure acculturative stress appropriate to immigrants in Spain, using expert and focus group review and has 42 items. The scale shows acceptable internal validity, and, consistent with other scales, suggests that immigration stress is a complex construct.

In this study we attempt to assess the utility of a simplified step-wise diagnostic algorithm to determinate the aetiology of encephalitis in daily clinical practice and to describe the main causes in our setting. This was a prospective cohort study of all consecutive cases of encephalitis in adult patients diagnosed between January 2010 and March 2015 at the University Hospital Vall d'Hebron in Barcelona, Spain. The aetiological study was carried out following the proposed step-wise algorithm. The proportion of aetiological diagnoses achieved in each step was analysed. Data from 97 patients with encephalitis were assessed. Following a simplified step-wise algorithm, a definite diagnosis was made in the first step in 53 patients (55 %) and in 12 additional cases (12 %) in the second step. Overall, a definite or probable aetiological diagnosis was achieved in 78 % of the cases. Herpes virus, L. monocytogenes and M. tuberculosis were the leading causative agents demonstrated, whereas less frequent aetiologies were observed, mainly in immunosuppressed patients. The overall related mortality was 13.4 %. According to our experience, the leading and treatable causes of encephalitis can be identified in a first diagnostic step with limited microbiological studies. L. monocytogenes treatment should be considered on arrival in some patients. Additional diagnostic effort should be made in immunosuppressed patients.

Background . Date palm's pollen has been identified as a source of allergy; the rate of sensitization of this pollen is between 6 and 29%. Objective . To determine the prevalence of sensitization to date palm in Marrakesh and to identify the clinical profile. Patients and Methods . This study is based on a questionnaire and the prick test on 7 allergens, in population aged 5 years and above with clinical symptoms suggesting allergic diseases, from November 2012 to February 2013 in Marrakech. Results . We included 468 patients (women: 79.5%). The prick tests were considered interpretable in 467 cases. The prevalence of skin sensitization to pollen of date palm was 6.6%. The 31 cases of sensitization to date palm involved 7 men and 24 women with an average age of 37.5 years. Cutaneous monosensitization to date palm's pollen was observed in 2 cases. Asthma, rhinitis, and conjunctivitis were recorded, respectively, in 48.4%, 93.5%, and 67.7%. Conclusion . Skin sensitization to pollen of date palm does not seem unusual among allergic patients in Marrakech and is comparable to that found in Casablanca (7%), Barcelona (6.6%), and Cartagena (6.1%).

To describe and compare levels of knowledge about HIV/AIDS and condom use in the immigrant population. We performed a cross-sectional study by means of a semi-structured questionnaire and face-to face interviews in 238 Latin American and Maghrebi users of medical centers in the Barcelona and North Barcelona-Maresme health areas. The questionnaire included sociodemographic variables and questions on sexual behavior and general knowledge about HIV/AIDS, transmission mechanisms, and means of prevention. A logistic regression model was used to identify the determinants of 'inadequate knowledge of HIV/AIDS'. A total of 53.8% of interviewees had inadequate knowledge of HIV/AIDS. Univariate analysis showed inadequate knowledge to be associated with being from the Maghreb, not living in Barcelona, being without work and not having educational qualifications. Multivariate analysis revealed that the only variables significantly associated with inadequate knowledge were being from the Maghreb as opposed to being from Latin America (OR=4.99; 95% CI: 2.74-5.10) and being unemployed as opposed to being employed (OR=2.59; 95% IC: 1.42-4.73). Condoms were seen as an effective prevention method, but 42.1% of interviewees did not use them in occasional relationships. Knowledge of routes of HIV transmission should be improved and mistaken ideas about infection should be eliminated among Latin American and Maghrebi immigrants. The immigrant population is a vulnerable group that ought to be prioritized to promote prevention programs adapted to its linguistic and cultural specificities.

Escherichia coli is one of the most frequent causes of late-onset neonatal sepsis. The aim of this study was to characterize an outbreak of neonatal sepsis occurring in the neonatal intensive care unit of the Hospital Clinic of Barcelona from April to August 2013. After presentation of the index case, all E. coli isolates from previously hospitalized neonates, health-care workers and neonates admitted to the neonatal intensive care unit from April to October 2013 were tested for K1 antigen positivity and epidemiologically compared by pulse-field gel electrophoresis. Furthermore, the E. coli K1 strains collected from neonates during this period were analyzed by different methods (serotyping, phylotyping, polymerase chain reaction of virulence factors, antimicrobial resistance and "in vitro" assays in Human Brain Microvascular Endothelial Cells (HBMEC)). An E. coli O18:K1:H7 sequence type 95 and phylogenetic group B2 strain was the cause of the outbreak involving 6 preterm neonates: 1 with late septicemia because of a urinary focus and 5 with late-onset septicemia and meningitis, 3 of whom died. All showed the same pulsotype, full resistance to ampicillin and intermediate resistance to gentamicin. The outbreak strain carried the pathogenicity island (PAI) IIJ96-like domain that could explain the high-grade bacteremia necessary to develop meningitis. All the E. coli isolates responsible for this outbreak belonged to a single clone suggesting a common source of infection, and it was categorized as O18:K1:H7. Despite the bacteria's pathogenicity has an important role in the severity of infection, the host-associated factors were crucial for the fatal outcomes.

The mass concentration, chemical composition and sources of quasi-ultrafine (quasi-UFP, PM0.25), accumulation (PM0.25-2.5) and coarse mode (PM2.5-10) particles were determined in indoor and outdoor air at 39 schools in Barcelona (Spain). Quasi-UFP mass concentrations measured (25.6 μg m-3 outdoors, 23.4 μg m-3 indoors) are significantly higher than those reported in other studies, and characterised by higher carbonaceous and mineral matter contents and a lower proportion of secondary inorganic ions. Results suggest that quasi-UFPs in Barcelona are affected by local sources in the schools, mainly human activity (e.g. organic material from textiles, etc.; contributing 23-46% to total quasi-UFP mass) and playgrounds (in the form of mineral matter, contributing about 9% to the quasi-UFP mass). The particle size distribution of toxicologically relevant metals and major aerosol components was characterised, displaying bimodal size distributions for most elements and components, and a unimodal distribution for inorganic salts (ammonium nitrate and sulphate) and elemental carbon (EC). Regarding metals, Ni and Cr were partitioned mainly in quasi-UFPs and could thus be of interest for epidemiological studies, given their high redox properties. Children exposure to quasi-UFP mass and chemical species was assessed by comparing the concentrations measured at urban background and traffic areas schools. Finally, three main indoor sources across all size fractions were identified by assessing indoor/outdoor ratios (I/O) of PM species used as their tracers: human activity (organic material), cleaning products, paints and plastics (Cl- source), and a metallic mixed source (comprising combinations of Cu, Zn, Co, Cd, Pb, As, V and Cr).

To evaluate the intensity and location of musculoskeletal pain suffered by students and professors from different postgraduate programs of the School of Dentistry of the University of Barcelona (Spain), to identify the variables related to the occurrence of musculoskeletal symptoms and signs, and to establish possible preventive measures for such disorders. A cross-sectional study was made among students and faculty members from different postgraduate courses of the School of Dentistry at the University of Barcelona between May and June 2007. A total of 74 dentists (54 postgraduate students and 20 faculty members) completed an anonymous questionnaire containing 19 questions. The variables were divided into three main groups: sociodemographic information, ergonomic features and musculoskeletal pain arising from professional practice. Most of the dentists (79.8%) had experienced some kind of musculoskeletal pain in the last 6 months. On comparing the different locations of pain (lumbar, cervical, dorsal, wrist, shoulder and others), the neck was found to be the most commonly affected location (58% of all subjects), and only 34% of the respondents took some preventive measures against musculoskeletal disorders. Women showed a higher frequency of intense pain involving the cervical, lumbar, dorsal and wrist areas (p<0.05). A higher incidence of wrist pain was recorded in professionals exclusively dedicated to oral surgery (p<0.05). No statistically significant correlation was found between the workload (hours) and pain in the different anatomical locations (p>0.05). An important incidence of pain symptoms secondary to musculoskeletal disorders was observed, particularly in the cervical region. Females and younger dentists showed a higher frequency of such symptoms. The implementation of preventive measures is necessary, in view of the high incidence of these disorders.

Smoking is a preventable cause of early death and the habit starts in adolescence. The aim of this study was to describe tobacco consumption in secondary school students in 2008 and trends in the last 20 years in Barcelona. We analyzed the trend in tobacco consumption by comparing data from 8 surveys carried out between 1987 and 2008 in the 8th (2nd year of Compulsory Secondary Education), 10th (4th year of Compulsory Secondary Education) and 12th (2nd year of Compulsory Secondary Education) years of secondary school. The FRESC questionnaire was used. Data on regular and daily consumption and associated factors in 2008 were gathered and compared with those corresponding to the previous studies. Percentages of annual change were calculated with Joinpoint regression and data were stratified by sex and year of education. In 2008, 6.1% of boys and 4.5% of girls in the 8th year, 15.8% and 20.4% of those in the 10th year, respectively, and 26.1% and 33.1% of those in the 12th year, respectively, were regular smokers. A strong association was noted between regular smoking and cannabis consumption in three school years, as well as with having friends who were smokers and poor school performance. At 15-16 years old, the average annual decrease from 1996 to 2008 was 6.8% in girls and 6.1% in boys. Adolescent smoking has been decreasing in the last few years in Barcelona. There is a strong association between tobacco use and cannabis consumption. Copyright © 2013 SESPAS. Published by Elsevier Espana. All rights reserved.

To quantify the concentration of respirable particles equal to or smaller than 2.5μm (PM(2.5)) as a marker of second-hand smoke (SHS) exposure in a sample of hospitality venues in Barcelona 2 years after the Spanish smoking law came into effect. We performed a cross-sectional descriptive study from October to December 2007. The study population consisted of 40 hospitality venues in Barcelona selected by a random route sampling, with representation of the different types of smoking regulation included in the law (smoking allowed, smoking ban and venues with smoking areas). SHS levels were quantified by measuring PM(2.5) concentrations, which were measured using a laser photometer (Side Pack AM 510 Personal Aerosol Monitor). The measurements were carried out for 5 minutes outside the venue and for 30 minutes inside the venue. In addition, observational variables related to the characteristics of the venue and signs of tobacco consumption were recorded. The concentration of PM(2.5) in venues where smoking was still allowed was five times higher than that in venues where smoking was banned (182μg/m(3) and 34μg/m(3), respectively) and exceeded the concentration established by the US Environmental Protection Agency (EPA) as harmful (35μg/m(3)). However, in venues where smoking was banned, the concentration was lower than the EPA standard and there were no significant differences with the outdoor PM(2.5) concentration. Two years after the introduction of the Spanish smoking law, SHS exposure in venues where smoking was allowed was q still very high, representing a significant health risk for hospitality workers.

We aimed to subclassify hepatocellular carcinoma (HCC) using Barcelona Clinic Liver Cancer intermediate and advanced stages, which include a highly heterogeneous population. From two registries ("random" and "voluntary" cohorts in the Korean Liver Cancer Study Group), patients who were newly diagnosed as HCC with intermediate or advanced stage between 2003 and 2005 were considered eligible. Overall survival (OS) was analyzed using Kaplan-Meier method with comparison by log-rank test. Patients with intermediate-stage HCC (n = 994) were subclassified according to tumor size and Child-Pugh class. Patients with tumor size < 5 cm (B1), those with tumor size ≥ 5 cm and Child-Pugh A (B2), and those with tumor size ≥ 5 cm and Child-Pugh B (B3) had median OS of 30.73, 20.60, and 9.23 months, respectively (P < 0.001 by log-rank test). Among patients with advanced stage HCC (n = 1746), patients were subclassified according to presence of significant portal vein invasion (sPVI; defined as portal vein invasion in lobar, main, or contralateral branch) and extrahepatic spread (EHS). Patients with neither sPVI nor EHS (C1), those with either sPVI or EHS (C2), and those with both sPVI and EHS (C3) had median OS of 8.43, 4.63, and 3.63 months, respectively (P < 0.001 by log-rank test). Subclassification of Barcelona Clinic Liver Cancer intermediate and advanced stages might be useful for determining patient prognosis and guiding treatment strategies for HCC. © 2015 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

Schools represent a critical microenvironment in terms of air quality due to the proximity to outdoor particle sources and the frequent lack of proper ventilation and filtering systems. Moreover, the population exposed in schools (i.e. children) represents a susceptible population due to their age. Air quality-based studies involving students' exposure at schools are still scarce and often limited to mass-based particle metrics and may thus underestimate the possible effect of sub-micron particles and particle toxicity. To this purpose, the present paper aims to evaluate the exposure to different airborne particle metrics (including both sub- and super-micron particles) and attached carcinogenic compounds. Measurements in terms of particle number, lung-deposited surface area, and PM fraction concentrations were measured inside and outside schools in Barcelona (Spain) and Cassino (Italy). Simultaneously, PM samples were collected and chemically analysed to obtain mass fractions of carcinogenic compounds. School time airborne particle doses received by students in classrooms were evaluated as well as their excess lung cancer risk due to a five-year primary school period. Median surface area dose received by students during school time in Barcelona and Cassino resulted equal to 110mm 2 and 303mm 2 , respectively. The risk related to the five-year primary school period was estimated as about 2.9×10 -5 and 1.4×10 -4 for students of Barcelona and Cassino, respectively. The risk in Barcelona is slightly higher with respect to the maximum tolerable value (10 -5 , according to the U.S. Environmental Protection Agency), mainly due to toxic compounds on particles generated from anthropogenic emissions (mainly industry). On the other hand, the excess lung cancer risk in Cassino is cause of concern, being one order of magnitude higher than the above-mentioned threshold value due to the presence of biomass burning heating systems and winter thermal inversion that cause larger doses and great amount of toxic compounds on particles.

Real-time measurements of ambient concentrations of gas-phase ammonia (NH3) were performed in Barcelona (NE Spain) in summer between May and September 2011. Two measurement sites were selected: one in an urban background traffic-influenced area (UB) and the other in the historical city centre (CC). Levels of NH3 were higher at CC (5.6 ± 2.1 μg m-3 or 7.5 ± 2.8 ppbv) compared with UB (2.2 ± 1.0 μg m-3 or 2.9 ± 1.3 ppbv). This difference is attributed to the contribution from non-traffic sources such as waste containers, sewage systems, humans and open markets more dense in the densely populated historical city centre. Under high temperatures in summer these sources had the potential to increase the ambient levels of NH3 well above the urban-background-traffic-influenced UB measurement station. Measurements were used to assess major local emissions, sinks and diurnal evolution of NH3. The measured levels of NH3, especially high in the old city, may contribute to the high mean annual concentrations of secondary sulfate and nitrate measured in Barcelona compared with other cities in Spain affected by high traffic intensity. Ancillary measurements, including PM10, PM2.5, PM1 levels (Particulate Matter with aerodynamic diameter smaller than 10 μm, 2.5 μm, and 1 μm), gases and black carbon concentrations and meteorological data, were performed during the measurement campaign. The analysis of specific periods (3 special cases) during the campaign revealed that road traffic was a significant source of NH3. However, its effect was more evident at UB compared with CC where it was masked given the high levels of NH3 from non-traffic sources measured in the old city. The relationship between SO42- daily concentrations and gas-fraction ammonia (NH3/(NH3 + NH4+)) revealed that the gas-to-particle phase partitioning (volatilization or ammonium salts formation) also played an important role in the evolution of NH3 concentration in summer in Barcelona.

Few studies have focused on pleural mesothelioma and environmental exposure in individuals residing around an industrial source of asbestos. The aim of this study is to determine whether residential distance and wind conditions are related to the risk of developing pleural mesothelioma. In this retrospective cohort study carried out in an area of Barcelona province (Catalonia, Spain), 24 environmental pleural mesothelioma cases were diagnosed between 2000 and 2009. We calculated the age-standardised incidence rate ratios of developing this disease in the population studied, taking into account the residential distance from the plant. For cases living within a 500-m radius of the plant, the geographical location in relation to the factory was also assessed. The incidence rate of environmental pleural mesothelioma was higher in the population living within 500 m of the plant than in those living in a radius of 500-2000 m and much higher than those living at 2000-10 000 m. The highest incidence rate ratio for pleural mesothelioma (161.9) was found in the southeast quadrant of the 500-m area, coinciding with the predominant wind direction. Residential distance from an industrial source of asbestos and local wind conditions have a considerable impact on the risk of developing environmental pleural mesothelioma.

Excavation sites such as those associated with the construction of subway lines, railways and highway tunnels are hazardous places, posing risks to workers, machinery and surrounding buildings. Many of these risks can be groundwater related. In this work we develop a general framework based on a probabilistic risk assessment (PRA) to quantify such risks. This approach is compatible with standard PRA practices and it employs many well-developed risk analysis tools, such as fault trees. The novelty and computational challenges of the proposed approach stem from the reliance on stochastic differential equations, rather than reliability databases, to compute the probabilities of basic events. The general framework is applied to a specific case study in Spain. It is used to estimate and minimize risks for a potential construction site of an underground station for the new subway line in the Barcelona metropolitan area.

Lognormal kriging for the assessment of reliability in groundwater quality control observation networks

USGS Publications Warehouse

Candela, L.; Olea, R.A.; Custodio, E.

1988-01-01

Groundwater quality observation networks are examples of discontinuous sampling on variables presenting spatial continuity and highly skewed frequency distributions. Anywhere in the aquifer, lognormal kriging provides estimates of the variable being sampled and a standard error of the estimate. The average and the maximum standard error within the network can be used to dynamically improve the network sampling efficiency or find a design able to assure a given reliability level. The approach does not require the formulation of any physical model for the aquifer or any actual sampling of hypothetical configurations. A case study is presented using the network monitoring salty water intrusion into the Llobregat delta confined aquifer, Barcelona, Spain. The variable chloride concentration used to trace the intrusion exhibits sudden changes within short distances which make the standard error fairly invariable to changes in sampling pattern and to substantial fluctuations in the number of wells. ?? 1988.

The relationship between environmental factors and the exacerbation of respiratory diseases has been widely studied. However, there are no studies examining the relationship between these factors and bronchiectasis exacerbations. Our objective was to analyse the association between various environmental factors and hospitalisation for bronchiectasis. This was a retrospective observational study conducted at two hospitals in Badalona (Barcelona). The number of hospital admissions for exacerbation of bronchiectasis between 2007 and 2015 was obtained. Through multiple regression we analysed the relationship between the number of exacerbations and mean monthly values of temperature, SO 2 , NO, NO 2 , O 3 and CO. Temperature, SO 2 , NO, NO 2 , O 3 and CO were significantly associated with an increase in admissions due to exacerbation of bronchiectasis. By controlling the effect of temperature on the pollution variables, only SO 2 maintained statistical significance (P=.008). We have detected an increase in hospital admissions for exacerbation of bronchiectasis with increases in the atmospheric concentration of SO 2 and the decrease in temperature. Prospective studies with different geographical locations to confirm these results are needed. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

Diagnostic imaging techniques, at present especially computed tomography (CT), have become the most important noninvasive method for the study of mummies because they enable high resolution images and three-dimensional reconstructions without damaging the mummified subject. We present a sarcophagus with a mummy hidden inside that was acquired by a gallery in Barcelona. The sarcophagus and mummy were examined by CT at the Hospital Universitari Sagrat Cor in Barcelona. A flexible clamp was used to obtain tissue samples for further study. The results showed the presence of an anatomically intact female human subject albeit with a destructured thorax and upper abdomen. Various metal objects were detected, corresponding to amulets, artificial eyes, and an external wooden brace. CT is an excellent noninvasive imaging technique for the detailed study of mummies, as it enables not only the anatomic identification of the mummified subject but also the obtainment of tissue samples for complementary analyses. The description of these findings enables us to know the major radiologic landmarks for the paleopathologic study of mummies. Copyright © 2015 SERAM. Published by Elsevier España, S.L.U.

The objectives of this paper are to analyze the Spanish scientific production in nursing, define its temporal evolution, its geographical and institutional distribution, and observe the interinstitutional collaboration. We analyze a comprehensive sample of Spanish scientific production in the nursing area extracted from the multidisciplinary database SciVerse Scopus. The nursing scientific production grows along time. The collaboration rate is 3.7 authors per paper and 61% of the authors only publish one paper. Barcelona and Madrid are the provinces with highest number of authors. Most belong to the hospitalary environment, followed closely by authors belonging to the university. The most institutions that collaborate, sharing authorship of articles are: University of Barcelona, Autonomous University of Barcelona and Clinic Hospital of Barcelona. The nursing scientific production has been increasing since her incorporation at the university. The collaboration rate found is higher than found for other papers. It shows a low decrease of occasional authors. It discusses the outlook of scientific collaboration in nursing in Spain, at the level of institutions by co-authorship of papers, through a network graph. It observes their distribution, importance and interactions or lack thereof. There is a strong need to use international databases for research, care and teaching, in addition to the national specialized information resources. Professionals are encouraged to normalization of the paper's signature, both, surnames and institutions to which they belong. It confirms the limited cooperation with foreign institutions, although there is an increasing trend of collaboration between Spanish authors in this discipline. It is observed, clearly defined three interinstitutional collaboration patterns. Copyright © 2012 Elsevier España, S.L. All rights reserved.

The purpose of this study was to ascertain the psychological impact of mammographic screening for women who receive negative results and for those who need additional non-invasive and invasive complementary investigations to exclude breast cancer (false positives). One hundred fifty women who attended a breast cancer screening programme in Barcelona, aged 50-69 years, were included in this study: 50 with negative results and 100 with false positive mammograms (50 underwent non-invasive and 50 underwent invasive complementary investigations). Participants worried little until they underwent mammography, but worries increased when a telephone call notified the women of the need for further testing. A substantial proportion of women requiring further assessment reported that they were at least somewhat worried about having breast cancer throughout the screening process (P < 0.0001). Nevertheless, levels of anxiety and depression, measured by the Hospital Anxiety and Depression Scale, showed no statistically significant differences among the three groups. In conclusion, although the women showed no psychological morbidity, there is a substantial psychological response in those with an abnormal screening mammogram.

To determine the clinical characteristics of Continuous Neuropathic Orofacial Pain in patients that suffer Persistent Idiopathic Facial Pain (PIFP), Painful Post-Traumatic Trigeminal Neuropathy (PPTTN) or Burning Mouth Syndrome (BMS) and to describe their treatment. A retrospective observational study was made, reviewing the clinical history of the patients diagnosed with Continuous Neuropathic Orofacial Pain between 2004 and 2011 at the Orofacial Pain Unit of the Master of Oral Surgery and Implantology of the University of Barcelona and at the Orofacial Pain Unit of the Teknon Medical Center of Barcelona. The average age of the patients with Continuous Neuropathic Orofacial Pain was 54.5, with a clear female predominance (86.9%, n=20). Of all patients, 60.9% (n=14) were suffering a PIFP, 21.7% (n=5) had a BMS and 17.4% (n=4) were presenting a PPTTN. The pain quality described by the patients with Continuous Neuropathic Orofacial Pain was oppressive (43.47%, n=10), widely represented by patients with PIFP, and burning (39.13%, n=9) being the only quality that described patients with BMS. The treatment carried out with the patients was only pharmacologic. The most used drugs for the treatment of PIFP and PPTTN were clonazepam (50%, n=9) and amitriptyline (44.44%, n=8). However, a 55.5% (n=10) of the patients with PIFP or PPTTN required the association of two or more drugs for a correct pain control. All the patients with BMS responded satisfactorily to clonazepam. Continuous Neuropathic Orofacial Pain is a little known condition among the general population, physicians and dentists. This favors a late diagnosis and inaccurate treatments which entail unnecessary suffering. It is important to inform both the general population and health professionals concerning this painful condition.

Policies that stimulate active transportation (walking and bicycling) have been related to heath benefits. This study aims to assess the potential health risks and benefits of promoting active transportation for commuting populations (age groups 16-64) in six European cities. We conducted a health impact assessment using two scenarios: increased cycling and increased walking. The primary outcome measure was all-cause mortality related to changes in physical activity level, exposure to fine particulate matter air pollution with a diameter <2.5 μm, as well as traffic fatalities in the cities of Barcelona, Basel, Copenhagen, Paris, Prague, and Warsaw. All scenarios produced health benefits in the six cities. An increase in bicycle trips to 35% of all trips (as in Copenhagen) produced the highest benefits among the different scenarios analysed in Warsaw 113 (76-163) annual deaths avoided, Prague 61 (29-104), Barcelona 37 (24-56), Paris 37 (18-64) and Basel 5 (3-9). An increase in walking trips to 50% of all trips (as in Paris) resulted in 19 (3-42) deaths avoided annually in Warsaw, 11(3-21) in Prague, 6 (4-9) in Basel, 3 (2-6) in Copenhagen and 3 (2-4) in Barcelona. The scenarios would also reduce carbon dioxide emissions in the six cities by 1,139 to 26,423 (metric tonnes per year). Policies to promote active transportation may produce health benefits, but these depend of the existing characteristics of the cities. Increased collaboration between health practitioners, transport specialists and urban planners will help to introduce the health perspective in transport policies and promote active transportation.

Hepatitis C virus (HCV) is the commonest cause of hepatocellular carcinoma (HCC) in the United States. The benefits of HCV therapy may be measured in part by the prevention of HCC and other complications of cirrhosis. The true cost of care of the HCV patient with HCC is unknown. One hundred patients were randomly selected from a cohort of all HCC patients with HCV at a US transplant center between 2003 and 2013. Patients were categorized by the primary treatment modality, Barcelona class, and ultimate transplant status. Costs included the unit costs of procedures, imaging, hospitalizations, medications, and all subsequent care of the HCC patient until either death or the end of follow-up. Associations with survival and cost were assessed in multivariate regression models. Overall costs included a median of $176,456 (interquartile range [IQR], $84,489-$292,192) per patient or $6279 (IQR, $4043-$9720) per patient-month of observation. The median costs per patient-month were $7492 (IQR, $5137-$11,057) for transplant patients and $4830 for nontransplant patients. The highest median monthly costs were for transplant patients with Barcelona A4 disease ($11,349) and patients who received chemoembolization whether they underwent transplantation ($10,244) or not ($8853). Transarterial chemoembolization and radiofrequency ablation were independently associated with a 28% increase and a 22% decrease in costs, respectively, with adjustments for the severity of liver disease and Barcelona class. These data represent real-world estimates of the cost of HCC care provided at a transplant center and should inform economic studies of HCV therapy. © 2015 American Cancer Society.

A detailed spatial and temporal assessment of urban NH3 levels and potential emission sources was made with passive samplers in six major Spanish cities (Barcelona, Madrid, A Coruña, Huelva, Santa Cruz de Tenerife and Valencia). Measurements were conducted during two different periods (winter-autumn and spring-summer) in each city. Barcelona showed the clearest spatial pattern, with the highest concentrations in the old city centre, an area characterised by a high population density and a dense urban architecture. The variability in NH3 concentrations did not follow a common seasonal pattern across the different cities. The relationship of urban NH3 with SO2 and NOX allowed concluding on the causes responsible for the variations in NH3 levels between measurement periods observed in Barcelona, Huelva and Madrid. However, the factors governing the variations in A Coruña, Valencia and Santa Cruz de Tenerife are still not fully understood. This study identified a broad variability in NH3 concentrations at the city-scale, and it confirms that NH3 sources in Spanish urban environments are vehicular traffic, biological sources (e.g. garbage containers), wastewater treatment plants, solid waste treatment plants and industry. The importance of NH3 monitoring in urban environments relies on its role as a precursor of secondary inorganic species and therefore PMX. Further research should be addressed in order to establish criteria to develop and implement mitigation strategies for cities, and to include urban NH3 sources in the emission inventories.

COPD case finding is currently recommended at primary and tertiary care levels only. To evaluate the feasibility of a community pharmacy program for COPD case finding in high-risk customers by means of spirometry. Pilot cross-sectional descriptive study in 13 urban community pharmacies in Barcelona, Spain, from April to May 2007. Customers >40 years old with respiratory symptoms and/or a history of smoking were invited to participate in the study during pharmacists' routine work shifts. High-risk customers were identified by means of a 5-item COPD screening questionnaire based on criteria of the Global Initiative for Chronic Obstructive Lung Disease, and were invited to perform spirometry accordingly. Those with an FEV(1)/FVC ratio less than 0.70 were referred to the hospital for a repeat spirometry. Of the 161 pharmacy customers studied, 100 (62%) scored 3 or more items in the COPD screening questionnaire, and after spirometry, 21 (24%) had an FEV(1)/FVC ratio<0.7. When these subjects with airflow limitation were offered referral to a hospital respiratory function laboratory for further assessments, 11 (52%) attended the appointment. Over 70% of spirometries were rated as being of acceptable quality. No significant differences were observed in lung function parameters between the pharmacy and hospital measurements. COPD case finding by spirometry in high-risk customers of urban community pharmacies is feasible. Similarly to primary care practitioners, pharmacists have access to high-risk, middle-aged subjects who have never been tested for COPD. Pharmacists can help with early detection of COPD if they are correctly trained.

Objective This study seeks to analyse the prevalence and correlates of electronic cigarette (e-cigarette) use, purchase location and satisfaction with its use in a sample of the general population of the city of Barcelona, Spain. Design, setting and participants We used participants from a longitudinal study of a representative sample of the adult (≥16 years old) population of Barcelona (336 men and 400 women). The field work was conducted between May 2013 and February 2014. We computed the prevalence, adjusted odds ratios (ORs) and their corresponding 95% confidence interval (CI). Results The prevalence of ever e-cigarette use was 6.5% (95% CI 4.7% to 8.3%): 1.6% current use, 2.2% past use and 2.7% only e-cigarette experimentation. 75% (95% CI 62.8% to 87.3%) of ever e-cigarette users were current cigarette smokers at the moment of the interview. E-cigarette use was more likely among current smokers (OR=54.57; 95% CI 7.33 to 406.38) and highly dependent cigarette smokers (OR=3.96; 95% CI 1.60 to 9.82). 62.5% of the ever users charged their e-cigarettes with nicotine with 70% of them obtaining the liquids with nicotine in a specialised shop. 39.6% of ever e-cigarette users were not satisfied with their use, a similar percentage of not satisfied expressing the smokers (38.9%) and there were no statistically significant differences in the satisfaction between the users of e-cigarettes with and without nicotine. Conclusions E-cigarette use is strongly associated with current smoking (dual use) and most users continue to be addicted to nicotine. Six out of 10 e-cigarette users preferred devices that deliver nicotine. The satisfaction with e-cigarette use is very low. PMID:25157186

The objective of this study is to describe the differences in the exposure to secondhand smoke (SHS) at home and at leisure time according to the day of the week (working and non-working day) which exposure occurs in Barcelona. We carried out a cross-sectional study of a representative sample of adult (>16 years) non-smokers in Barcelona before the Spanish smoking law came into effect (years 2004-2005). We studied the prevalence of exposure to SHS at home and leisure time by means of a questionnaire and a biomarker (salivary cotinine). The questionnaire included questions on exposure to SHS on working days and nonworking days. The prevalence of exposure to SHS at home was 27.4% (6.8% exposed only on working days, 5.7% exposed only on non-working days, and 14.9% exposed on both working and non-working days). The prevalence of exposure to SHS at leisure time was 61.3% (10.7% exposed only on working days, 13.6% exposed only on non-working days, and 37.0% exposed on both working and non-working days). The exposure to SHS only on non-working days at leisure time decreases with age (χ(2) of trend = 183.7; p<0.001) and increases with the educational level (χ(2) of trend = 78.8; p<0.001). Participants who had reported to be exposed to SHS at home on working and non-working days showed higher levels of salivary cotinine concentration, regardless of sex, age group, and educational level. In conclusion, the exposure to SHS occurs mainly during leisure time. Questions on SHS exposure according to working and non-working days allow to characterizing the exposure to SHS, especially when the exposure occurs at leisure time.

We report a case of a 55-year-old male with chronic hepatitis C virus infection and compensated liver disease treated with sorafenib for advanced hepatocarcinoma (Barcelona Clinic Liver Cancer stage C). At follow-up, the patient developed hypertension, which was well controlled with beta-blocker medication, and an aortic dilation detected by abdominal computerized tomography and echocardiography. There are some reports of the side effects of sorafenib on the cardiovascular system. The patient had no cardiac or aortic pathology before the start of this palliative chemotherapy. There is an article that describes the development of an aortic aneurysm in a patient with uncontrolled hypertension, who received treatment with sorafenib for renal carcinoma. However, our patient had a good control of blood pressure. The adverse vascular effects of Sorafenib may be due to the inhibition of the proliferation of vascular endothelial muscle cells. We believe that this case illustrates a probable relationship between sorafenib and aortic dilatation according to the Karch and Lasagna causality algorithm.

We estimate demand curves for a one month reduction in waiting time for cataract surgery based on survey data collected in 1992 in Manitoba, Barcelona, and Denmark. Patients answered, "Would you be willing to pay [Bid, B] to reduce your waiting time for cataract surgery to less than one month?" Controlling for SES and visual status, Barcelonan patients have greater WTP for shortened waiting time than the Danes and Manitobans. We estimate the value (in 1992 $) of lost consumer surplus due to the cataract surgery queue at $128 per patient in Manitoba, $160 in Denmark, and $243 in Barcelona.

In the framework of a Spanish Space Project, the instrumentation of sea level measurements has been improved by providing the Barcelona site with a radar tide gauge and with a continuous GPS station nearby. The radar tide gauge is a Datamar 3000C device and a Thales Navigation Internet-Enabled GPS Continuous Geodetic Reference Station (iCGRS) with a choke ring antenna. It is intended that the overall system will constitute a CGPS Station of the ESEAS (European Sea Level) and TIGA (GPS Tide Gauge Benchmark Monitoring) networks. Puertos del Estado (Spanish Harbours) installed the tide gauge station at Ibiza harbour in January 2003. The station belongs to the REDMAR network, composed at this moment by 21 stations distributed along the whole Spanish waters, including also the Canary islands. The tide gauge also belongs to the ESEAS (European Sea Level) network. At the Barcelona harbour they have installed a radar tide gauge near a GPS station belonging to Puerto de Barcelona. L'Estartit floating tide gauge was set up in 1990. Data are taken in graphics registers from each two hours the mean value is recorded in an electronic support. L'Estartit tide gauge series provides good quality information about the changes in the sea heights at centimeter level, that is the magnitude of the common tides in the Mediterranean. Two airborne calibration campaigns carrying an Optech Lidar ALTM-3025 (ICC) were made on June 16, 2007 with a Partenavia P-68 and October 12, 2007, with a Cessna Caravan 208B flying along two ICESat target tracks including crossover near l'Estartit. The validation of this new technology LIDAR may be useful to fill coastal areas where satellite radar altimeters are not measuring due to the large footprint and the resulting gaps of about 15-30 km within the coastline. Measurements with a GPS Buoy at l'Estartit harbour were made during the June experience and a GPS reference station was installed in Aiguablava. On October 12, 2007, another LIDAR campaign was made at night at the same time of the ICESat overflying. A description of the actual geodetic CGPS infrastructures at Ibiza, l'Estartit and Barcelona is presented as their applications to sea level monitoring and altimeter calibration.

The aim of the current study was to examine and compare dieting and unhealthy weight-control behaviours (UWCB) in population-based samples in two large urban areas in Spain (Barcelona) and in the USA (Twin Cities of Minneapolis and St. Paul, Minnesota). Additionally, use of UWCB across weight categories was explored in both samples. Participants included 1501 adolescents from Barcelona (48% girls, 52% boys) and 2793 adolescents from the Twin Cities (53% girls, 47% boys). The main outcome measures were dieting, UWCB (less extreme and extreme) and weight status. Although dieting and UWCB were prevalent in both samples, particularly among girls, the prevalence was higher in the US sample. In both countries, the report of dieting and use of UWCB was highest among overweight and obese youth. Prevention interventions that address the broad spectrum of eating and weight-related problems should be warranted in light of the high prevalence and co-occurrence of overweight and unhealthy weight-related behaviours.

The evaluation of research production and productivity is becoming increasingly necessary for universities. Having reliable and clear data is extremely useful in order to uncover strengths and weaknesses. The objective of this article is to update the research ranking of Spanish public universities with the 2013 data. Assessment was carried out based on articles in journals indexed in the JCR, research periods, R+D projects, doctoral theses, FPU grants, doctoral studies awarded with a citation of excellence, and patents, providing a rating, both for each individual indicator and globally, in production and productivity. The same methodology as previous editions was followed. In the global ranking, the universities with a higher production are Barcelona, Complutense of Madrid, and Granada. In productivity, the first positions are held by the universities Pompeu Fabra, Pablo de Olavide, and the Autonomous University of Barcelona. Differences can be found between the universities in production and productivity, while there are also certain similarities with regard to the position of Spanish universities in international rankings.

Towards unity for health in the Barceloneta: an innovative experience in community-based primary health care.

This paper describes a unique experience in community-based primary care in the Barceloneta, an economically deprived neighbourhood in Barcelona, Spain. The paper analyzes the reasons for the successes and failures of the project in light of TUFH principles. The Primary Care Team (PCT) that staffed and ran the Health Centre in the Barceloneta facilitated the active participation of entities and individuals from the neighbourhood in deciding questions of care provision and resource allocation. They also collaborated with other service providers in the neighbourhood including pharmacists, with whom the PCT developed a program for monitoring diabetic and hypertensive patients in the local pharmacies. The health centre registered some of the best outcomes in Barcelona, including: time spent with each patient; capacity for the physicians to resolve patient visits without a referral; and patient satisfaction. Outcomes for patients followed by their local pharmacists were equivalent to those seen in the clinic, with lower costs. Despite these impressive results, conflicts among and between various stakeholders led to the project's termination. Innovations in any system can lead to conflicts of interest between stakeholders, derailing even demonstrably effective programs. A stable partnership with other stakeholders, particularly the community and health care administrators, in this case, is key. However, the community is not monolithic, and efforts must be made to ensure that other stakeholders do not widen intercommunity disputes. Effective dissemination of information on the impact of the project on the population is important to maintain relationships with the various stakeholders.

The overall incidence of spinal tuberculosis (TB) appears to be stable or declining in most European countries, but with an increasing proportion of cases in the foreign-born populations. We performed a retrospective observational study (1993-2014), including all cases of spinal TB diagnosed at a Barcelona hospital to assess the epidemiological changes. Fifty-four episodes (48·1% males, median age 52 years) of spinal TB were diagnosed. The percentage of foreign-born residents with spinal TB increased from 14% to 45·2% in the last 10 years (P = 0·017). Positive Mycobacterium tuberculosis testing in vertebral specimens was 88·2% (15/17) for GeneXpert MTB/RIF. Compared with natives, foreign-born patients were younger (P < 0·01) and required surgery more often (P = 0·003) because of higher percentages of paravertebral abscess (P = 0·038), cord compression (P = 0·05), and persistent neurological sequelae (P = 0·05). In our setting, one-third of spinal TB cases occurred in non-native residents. Compared with natives, foreign-born patients were younger and had greater severity of the disease. The GeneXpert MTB/RIF test may be of value for diagnosing spinal TB.

The incidence of invasive aspergillosis has increased worldwide. Information regarding the clinical characteristics of patients with extrapulmonary involvement is scarce. We aimed to describe the pathogenesis, characteristics and outcomes of patients with invasive aspergillosis and extrapulmonary disease. A retrospective study conducted in a university hospital in Barcelona, Spain (1995-2011). A total of 12 cases of invasive aspergillosis and extrapulmonary involvement were found. The most common clinical manifestations were invasive sinusitis, early postoperative prosthetic valve endocarditis, fungaemia, postoperative meningitis, multiple brain abscesses and lumbar spondylitis with epidural abscess. Sinusitis occurred frequently in patients without immunosuppression and had invasive brain involvement in one case. Endocarditis was associated with multiple septic metastases. Concomitant lung involvement was documented in 5 cases. The strains isolated were Aspergillus fumigatus (5), Aspergillus flavus (3), and Aspergillus niger (2). The species of Aspergillus was not established for 3 isolates. All patients were treated with antifungals and surgery was performed in 8 cases. Outcome was related with the source of infection; all patients with invasive sinusitis survived, while the remaining patients had a high mortality rate (88%). Invasive aspergillosis with extrapulmonary involvement is rare. The most common presentation is invasive sinusitis, which has a lower mortality. Other clinical forms with extrapulmonary involvement were associated with severe immunosuppression or previous surgery, and had a poor outcome. Copyright © 2011 Revista Iberoamericana de Micología.

The determination of global and regional mean sea level variations with accura-cies better than 1 mm/yr is a critical problem, the resolution of which is central to the current debate on climate change and its impact on the environment. Highly accurate time series from both satellite altimetry and tide gauges are needed. Measuring the sea surface height with in-situ tide gauges and GPS receivers pro-vides an efficient way to control the long term stability of the radar altimeters and other applications as the vertical land motion and studies of sea level change. L’Estartit tide gauge is a classical floating tide gauge set up in l’Estartit harbour (NE Spain) in 1990. Data are taken in graphics registers from which each two hours the mean value is recorded in an electronic support and delivered to the Permanent Service for Mean Sea level (PSMSL). Periodic surveying campaigns along the year are carried out for monitoring possible vertical movement of the geodetic benchmark adjacent to the tide gauge. Puertos del Estado (Spanish Harbours) installed the tide gauge station at Ibiza har-bour in January 2003 and a near GPS reference station. The station belongs to the REDMAR network, composed at this moment by 21 stations distributed along the whole Spanish waters, including also the Canary islands (http://www.puertos.es). The tide gauge also belongs to the ESEAS (European Sea Level) network. A description of the actual infrastructure at Ibiza, Barcelona and l’Estartit har-bours is presented.The main objective is the implementation of these harbours as a precise geodetic areas for sea level monitoring and altimeter calibration. Actually is a CGPS with a radar tide gauge from Puertos del Estado and a GPS belonging to Puerto de Barcelona. A precise levelling has been made by the Cartographic Insti-tute of Catalonia, ICC. The instrumentation of sea level measurements has been improved by providing the Barcelona site with a radar tide gauge Datamar 3000C device and a Thales Navigation Internet-Enabled GPS Continuous Geodetic Ref-erence Station (iCGRS) with a choke ring antenna, located at the EPSEB of the Technical University of Catalonia, UPC.

Policies that stimulate active transportation (walking and bicycling) have been related to heath benefits. This study aims to assess the potential health risks and benefits of promoting active transportation for commuting populations (age groups 16–64) in six European cities. We conducted a health impact assessment using two scenarios: increased cycling and increased walking. The primary outcome measure was all-cause mortality related to changes in physical activity level, exposure to fine particulate matter air pollution with a diameter <2.5 μm, as well as traffic fatalities in the cities of Barcelona, Basel, Copenhagen, Paris, Prague, and Warsaw. All scenarios produced health benefits in the six cities. An increase in bicycle trips to 35% of all trips (as in Copenhagen) produced the highest benefits among the different scenarios analysed in Warsaw 113 (76–163) annual deaths avoided, Prague 61 (29–104), Barcelona 37 (24–56), Paris 37 (18–64) and Basel 5 (3–9). An increase in walking trips to 50% of all trips (as in Paris) resulted in 19 (3–42) deaths avoided annually in Warsaw, 11(3–21) in Prague, 6 (4–9) in Basel, 3 (2–6) in Copenhagen and 3 (2–4) in Barcelona. The scenarios would also reduce carbon dioxide emissions in the six cities by 1,139 to 26,423 (metric tonnes per year). Policies to promote active transportation may produce health benefits, but these depend of the existing characteristics of the cities. Increased collaboration between health practitioners, transport specialists and urban planners will help to introduce the health perspective in transport policies and promote active transportation.

An intervention to promote the development of an allergen control plan (ACP) and preventive measures for the management of allergens in school food services was implemented in all schools of Barcelona city over a three-year period (2013-2015) by the public health services. The present study aimed to assess changes regarding the management of food allergens in school food services in Barcelona after an intervention conducted by the public health services of the city. School meal operators of a random sample of 117 schools were assessed before and after the intervention using a structured questionnaire. The questionnaire collected general information on the students and their demand for special menus, and included 17 closed questions regarding the implementation of specific preventive measures for the management of allergens. Based on these 17 questions, a food safety score was calculated for each school. The improvement in these scores was evaluated. The results showed positive increments in the percentage of implementation of 12 of the 17 preventive measures assessed. The percentage of school food services with an implemented ACP increased by 49%. Schools with external and internal food supplies increased their scores by 16.5% and 19.6%, respectively. The greatest improvements were observed in smaller food services and in schools located in districts with low gross household incomes. The intervention was effective in improving school food services' management of allergens and in reducing the differences found among food services in the pre-intervention survey. We must also focus efforts on reducing socio-economic inequalities linked to the management of allergens. Copyright © 2018 SEICAP. Published by Elsevier España, S.L.U. All rights reserved.

We analyzed 212 group B streptococci (GBS) from newborns with invasive infections in the area of Barcelona, Spain, between 1992 and 2009, with the aim of documenting changes in the prevalences of serotypes, antimicrobial resistance, and genetic lineages and evaluating their associations with either early-onset disease (EOD) or late-onset disease (LOD). Serotypes III (n = 118) and Ia (n = 47) together accounted for nearly 78% of the isolates. All isolates carried an alpha or alpha-like protein gene, and specific associations between genes and serotypes, such as serotype Ib and bca, serotype II and bca, serotype III and rib, and serotype V and alp3, reflected the presence of particular genetic lineages. Macrolide resistance (14.2%) was significantly associated with serotype V. Pulsed-field gel electrophoresis (PFGE) clustering was an excellent predictor of serotype and antibiotic resistance. The combination of PFGE and multilocus sequence typing revealed a large number of genetically distinct lineages. Still, specific lineages were dominant in our collection, particularly the serotype III/ST17/rib lineage, which had enhanced potential to cause LOD. Serotype Ia was concentrated in a single PFGE cluster composed of two genetic lineages: ST23/eps and ST24/bca. The ST24/bca sublineage of serotype Ia, which is found infrequently elsewhere, may be emerging as an important cause of neonatal invasive infections in the Mediterranean region. In spite of the introduction of prophylaxis, resulting in a pronounced decline in the frequency of EOD, the study revealed a remarkably stable clonal structure of GBS causing neonatal infections in Barcelona over a period of 18 years.

A third to half of penile invasive squamous cell carcinomas are human papillomavirus (HPV) related. Warty (condylomatous), warty-basaloid, and basaloid carcinomas are the most common subtypes associated with HPV. Less frequent are clear cell and lymphoepithelioma-like carcinomas. Here we report a novel penile tumor associated with HPV. Twelve cases were selected from 1010 penile carcinomas, part of an international HPV detection study conducted at the Institut Català d'Oncologia, Barcelona, Spain. Immunostaining with p16 was performed on all cases, and HPV-mRNA detection was also performed. En bloc full tumor staining was the utilized criteria for positivity of p16. For HPV-DNA detection, whole-tissue section polymerase chain reaction analysis was performed by SPF10-DEIA-LiPA25 (version 1). The patients' ages ranged from 42 to 92 years (average, 71 y). The tumor was most commonly located in the glans. A characteristic microscopic finding was the presence of a moderate to dense tumor-associated inflammatory cell infiltrate composed of neutrophils, lymphocytes, plasma cells, or eosinophils. Tumors grew in large solid sheets, nests, or had a trabecular pattern. Cells were large and poorly differentiated or anaplastic. Keratinization was minimal or absent. Nuclei were large with prominent nucleoli. Mitoses were numerous. Tumor necrosis was common. Deep invasion of the corpora cavernosa was frequent. p16 and HPV-DNA were positive in all cases, whereas mRNA detection was positive in 9 cases only. The prevalent genotype was HPV16 (9 cases, 75%). Other genotypes were HPVs 58, 33, and 66. Medullary carcinomas of the penis are morphologically distinctive HPV-related high-grade neoplasms affecting older individuals. More studies are necessary to delineate the epidemiological, clinical, and molecular features of this unusual penile neoplasm.

Determine the presence of "burnout" syndrome and characteristic personality patterns in the students and faculty of three graduate programs in Dentistry at the University of Barcelona: Department of Oral Surgery and Implantology, Department of Orthodontics and Department of Integrated Dentistry. The study was carried out in 78 dentists. The level of "burnout" was evaluated using the Maslach Burnout Inventory, socio-demographic variables and, finally, the personality test. Oral surgeons constituted the group of high-level "burnout". The profile of an individual with a propensity to "burn out" is a single man, with a median age of 27, that is in the first years of the graduate program and that combines studies with 30 hours of clinical practice and/or other work (p<0,05). Narcissistic and borderline are the types of personality most frequently found in the individuals that present "burnout" syndrome (p<0,05). In general, no high levels of "burnout" were registered in the studied population, only 2-3%, if applying strict definition of "burnout", and 10% if these criteria were amplified. We believe it is necessary to identify the individuals with a tendency towards "burnout", in order to establish preventive measures and avoid future negative behaviour at work as well as at the personal level.

Two new species related to Candida glabrata, i.e., Candida nivariensis and Candida bracarensis, have been proposed. The occurrence of these species among isolates collected in a Spanish mycology reference laboratory in 2008-2009 was reviewed. In addition, strains recovered as part of an active population-based surveillance of candidemia conducted in Barcelona between 2002 and 2003 were also analyzed. Among 143 clinical isolates received in 2008-2009, three (2%) were identified as C. bracarensis and none as C. nivariensis through sequencing of their ribosomal DNA. Of the 31 strains initially identified as C. glabrata in the 2002-2003 population-based study (0.38 cases/100,000 population), none were found to belong to these related new species. Results from in vitro susceptibility studies of C. bracarensis isolates were comparable to those found with C. glabrata. Since new and cryptic species have been described, periodic surveillance including the use of molecular identification methods seems to be necessary in order to determine their frequency, geographical distribution and susceptibility profile.

Description of an outbreak of legionnaires' disease originating in one of the cooling towers of a hospital. This study included patients with confirmed pneumonia caused by Legionella pneumophila serogroup 1 and related to the Vallcarca neighborhood of Barcelona (Spain) in August 2004. Exposure was determined by a standardized questionnaire. An environmental investigation was carried out to identify the source of the outbreak. A descriptive analysis including incidence rates estimation was performed, as well as molecular study to document the genetic identity among human and environmental strains. Thirty-three cases of L. pneumophila pneumonia were detected. Median age was 68 years and 70% of the affected patients were men. Incidence rate among residents in less than 200 meters of the source and older than 65 was 888.9 cases/100,000 inhabitants. Lethality rate was 6%. Four seasonal cooling towers that were not registered with the authorities were identified in a health care center. L. pneumophila was isolated from all four and at least one colony in each tower had the same genetic profile as the strains isolated from patients. An association was demonstrated between a community outbreak of legionellosis and unregistered seasonal cooling towers located in a hospital. All risk facilities should be registered and inspected to ensure that they fulfill current legislation requirements.

The mass concentration, chemical composition and sources of quasi-ultrafine (quasi-UFP, PM0.25), accumulation (PM0.25-2.5) and coarse mode (PM2.5-10) particles were determined in indoor and outdoor air at 39 schools in Barcelona (Spain). Quasi-UFP mass concentrations measured (25.6 μg m-3 outdoors, 23.4 μg m-3 indoors) are significantly higher than those reported in other studies, and characterised by higher carbonaceous and mineral matter contents and a lower proportion of secondary inorganic ions. Results suggest that quasi-UFPs in Barcelona are affected by local sources in the schools, mainly human activity (e.g. organic material from textiles, etc., contributing 23-46% to total quasi-UFP mass) and playgrounds (in the form of mineral matter, contributing about 9% to the quasi-UFP mass). The particle size distribution patterns of toxicologically relevant metals and major aerosol components was characterised, displaying two modes for most elements and components, and one mode for inorganic salts (ammonium nitrate and sulfate) and elemental carbon (EC). Regarding metals, Ni and Cr were partitioned mainly in quasi-UFPs and could thus be of interest for epidemiological studies, given their high redox properties. Exposure of children to quasi-UFP mass and chemical species was assessed by comparing the concentrations measured at urban background and traffic areas schools. Finally, three main indoor sources across all size fractions were identified by assessing indoor / outdoor ratios (I / O) of PM species used as their tracers: human activity (organic material), cleaning products, paints and plastics (Cl- source), and a metallic mixed source (comprising combinations of Cu, Zn, Co, Cd, Pb, As, V and Cr). Our results support the need to enforce targeted legislation to determine a minimum "safe" distance between major roads and newly built schools to reduce exposure to traffic-derived metals in quasi-UFPs.

Performance assessment of healthcare services is receiving greater attention due to increasing health care expenditures, greater expectations among the population, and the need to obtain results from the invested resources. Taking advantage of the existing experience of the Agència de Salut Pública de Barcelona and the Consorci Sanitari de Barcelona, which compared the healthcare services of Barcelona and Montreal, a grant from the Agència d'Avaluació de Tecnologia i Recerca Mèdiques, and the health planning interest of the Departament de Salut, the performance assessment of the Catalan healthcare service project was started in Catalonia in 2005. This article aims to present the development of the project, to provide some examples that illustrate the kind of numerical and graphical information that could be obtained and the kind of analysis that could be performed, to provide possible explanations for the results shown, and to discuss some limitations and implications. Currently, the added value of this project is that it identifies the extent to which the healthcare system is achieving its objectives, establishes a set of homogeneous indicators that could be used in the future, and is a key tool in the development of the Central de Resultats del Departament de Salut de la Generalitat de Catalunya.

Subway systems worldwide transport more than 100 million people daily; therefore, air quality on station platforms and inside trains is an important urban air pollution issue. We examined the microbiological composition and abundance in space and time of bioaerosols collected in the Barcelona subway system during a cold period. Quantitative PCR was used to quantify total bacteria, Aspergillus fumigatus, influenza A and B, and rhinoviruses. Multitag 454 pyrosequencing of the 16S rRNA gene was used to assess bacterial community composition and biodiversity. The results showed low bioaerosol concentrations regarding the targeted microorganisms, although the bacterial bioburden was rather high (10 4 bacteria/m 3 ). Airborne bacterial communities presented a high degree of overlap among the different subway environments sampled (inside trains, platforms, and lobbies) and were dominated by a few widespread taxa, with Methylobacterium being the most abundant genus. Human-related microbiota in sequence dataset and ascribed to potentially pathogenic bacteria were found in low proportion (maximum values below 2% of sequence readings) and evenly detected. Hence, no important biological exposure marker was detected in any of the sampled environments. Overall, we found that commuters are not the main source of bioaerosols in the Barcelona subway system. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Currently, there is an intensive debate about the regulation of the use of electronic cigarettes (e-cigarettes) in indoor places. The aim of this study was to assess the attitudes toward e-cigarette use in indoor workplaces and selected public and private venues among the general population in Barcelona (Spain) in 2013-2014. This is a cross-sectional study of a representative sample of the population of Barcelona (n = 736). The field work was conducted between May 2013 and February 2014. We computed the prevalence and the adjusted odds ratios (OR) derived from multivariable logistic regression models. The awareness of e-cigarettes was 82.3%. Forty five percent of respondents did not agree with the use of e-cigarettes in public places and 52.3% in workplaces. The proportion of disapproval of the use of e-cigarettes in indoor places was higher at 71.5% for schools and 65.8% for hospitals and health care centers; while the prevalence of disapproval of e-cigarette use in homes and cars was lower (18.0% and 32.5%, respectively). Respondents who disagreed on the use of e-cigarettes in indoor workplaces were more likely to be older (OR = 1.64 and 1.97 for groups 45-64 and ≧65 years old, respectively), those with a high educational level (OR = 1.60), and never and former smokers (OR = 2.34 and 2.16, respectively). Increased scores in the Fagerström test for cigarette dependence were also related to increased support for their use. Based on this population based study, half of the general population of Barcelona does not support the use of e-cigarettes in indoor workplaces and public places, with the percentage reaching 65% for use in schools, hospitals and health care centers. Consequently, there is good societal support in Spain for the politicians and legislators to promote policies restricting e-cigarettes use in workplaces and public places, including hospitality venues.

The Annual Congress of the European Society of Cardiology (ESC) was held in Barcelona from 30th August to 3rd September 2014. More than 30,300 attendees from around the world shared the latest original research, including 27 clinical Hot Line studies, 12 basic science Hot Lines, 15 clinical trial updates, 19 registry studies, and 4,597 abstracts. Many important issues were presented, including novel treatment strategies for heart failure, acute coronary syndrome, interventional treatment for structural heart disease, renal denervation, novel anticoagulant therapies, atrial fibrillation and so on. In addition, 5 new ESC clinical practice guidelines (ie, myocardial revascularization, non-cardiac surgery, acute pulmonary embolism, hypertrophic cardiomyopathy, and aortic disease) were launched. It should be noted that Japan has recently been ranked in the top position in terms of the number of abstract submissions. Based on these activities, the ESC Congress has been recognized as the dominant scientific and educational forum for healthcare professionals in cardiology. We report the highlights and several key presentations of the ESC Congress 2014. The scientific activities and growing contributions of Japanese cardiologists or cardiovascular surgeons enhance the favorable relationship between the ESC and the Japanese Circulation Society.

Clinical research has shown the mental health benefits of dance practice. This has become a significant subject of inquiry in psychotherapeutic settings for the elderly and adolescents. However, the relationship between dance practice and correlates of psychological well-being, such as mindfulness and life satisfaction (LS)-two relevant indicators of mental health, has been explored relatively little in young women. The present study contrasted mindfulness and LS in young women (n = 81) who practiced dance regularly in three modern dance schools in the Province of Barcelona with a control group of non-practitioners (n = 120) studying at a university in Barcelona. The data were collected during the first semester of 2015, and the total sample had an average age of 20.88 ± 3.36 years. Analyses of covariance showed higher levels of both mindfulness and LS in the dance practitioners, while a multiple regression analysis showed that, after controlling for age, dance was the factor most strongly associated with LS, explaining 28% of the variance in LS. These results are discussed in terms of the embodiment theory, and conclusions suggest that dance may be an effective gender-focused practice to enhance well-being and promote mental health in young women.

Exposure to air pollution has been shown to adversely affect foetal development in the case of pregnant women. The present study aims to investigate the PM composition and sources influencing personal exposure of pregnant women in Barcelona. To this end, indoor, outdoor and personal exposure measurements were carried out for a selection of 54 pregnant women between November 2008 and November 2009. PM2.5 samples were collected during two consecutive days and then analysed for black smoke (BS), major and trace elements, and polycyclic aromatic hydrocarbons (PAHs) concentrations. Personal information such as commuting patterns and cosmetics use was also collected. PM2.5 concentrations were higher for personal samples than for indoor and outdoor environments. Indoor, outdoor and personal BS and sulphate concentrations were strongly correlated, although some specific indoor and outdoor sulphate sources may exist. Average trace elements concentrations were similar indoor, outdoor and for personal exposure, but the correlations were moderate for most of them. Most of the PAHs concentrations showed strong correlations indoor-outdoor. A source apportionment analysis of the PM composition data by means of a Positive Matrix Factorization (PMF) resulted in the identification of six sources for the outdoor and indoor environments: secondary sulphate, fueloil + sea salt (characterized by V, Ni, Na and Mg), mineral, cigarette (characterized by K, Ce, Cd, benzo(k)fluoranthene and benzo(ghi)perylene), road traffic (characterized by BS and low weight PAHs), and industrial (characterized by Pb, Sn, Cu, Mn and Fe). For personal exposure two specific sources were found: cosmetics (characterized by abundance of Ca, Li, Ti and Sr and the absence of Al) and train/subway (characterized by Fe, Mn, Cu and Ba). The contribution of the sources varied widely among women, especially for cigarette (from zero to up to 4 μg m-3), train/subway (up to more than 6 μg m-3) and cosmetics (up to more than 5 μg m-3). The source contributions showed generally strong correlations indoor-outdoor although the infiltration efficiencies varied among homes. This study emphasizes the importance of relying on personal exposure in epidemiological studies assessing the impact of air pollution on human health.

PM1 aerosol characterization on organic tracers for biomass burning (levoglucosan and its isomers and dehydroabietic acid) was conducted within the AERTRANS project. PM1 filters (N = 90) were sampled from 2010 to 2012 in busy streets in the urban centre of Madrid and Barcelona (Spain) at ground-level and at roof sites. In both urban areas, biomass burning was not expected to be an important local emission source, but regional emissions from wildfires, residential heating or biomass removal may influence the air quality in the cities. Although both areas are under influence of high solar radiation, Madrid is situated in the centre of the Iberian Peninsula, while Barcelona is located at the Mediterranean Coast and under influence of marine atmospheres. Two extraction methods were applied, i.e. Soxhlet and ASE, which showed equivalent results after GC-MS analyses. The ambient air concentrations of the organic tracers for biomass burning increased by an order of magnitude at both sites during winter compared to summer. An exception was observed during a PM event in summer 2012, when the atmosphere in Barcelona was directly affected by regional wildfire smoke and levels were four times higher as those observed in winter. Overall, there was little variation between the street and roof sites in both cities, suggesting that regional biomass burning sources influence the urban areas after atmospheric transport. Despite the different atmospheric characteristics in terms of air relative humidity, Madrid and Barcelona exhibit very similar composition and concentrations of biomass burning organic tracers. Nevertheless, levoglucosan and its isomers seem to be more suitable for source apportionment purposes than dehydroabietic acid. In both urban areas, biomass burning contributions to PM were generally low (2 %) in summer, except on the day when wildfire smoke arrive to the urban area. In the colder periods the contribution increase to around 30 %, indicating that regional biomass burning has a substantial influence on the urban air quality.

Urban groundwater is a valuable resource since its quantity is larger than frequently expected due to additional recharge sources (Lerner, 2002; Vázquez-Suñé et al., 2003). Its interaction with the complex infrastructures network makes the water authorities a challenge to ensure a proper water management. Necessary datasets to ensure a suitable water management have normally different origins and formats. At the same time, the water management of a city involves different decision makers with different knowledges. In this scenario, it is a necessity to create a common environment where different actors would be able to understand and analyze problems in the same way. It should be also necessary to store, analyze and visualize all the required data in the same formats within its geographical context by using standardized specific tools. To apply these recommendations for the urban groundwater management of the Barcelona City Council, we have implemented a software platform developed in a Geographic Information System (GIS) environment. These GIS-based tools will give support to the users for storing, managing, and analyzing geological, hydrogeological and hydrochemical data in 2D and in a 3D context (Velasco et al., 2013). This implementation will improve the groundwater management in Barcelona city optimizing the analysis and decision making processes. References Lerner, D.N., (2002).

Only a few cases of nosocomial Legionella sp. infection have been reported in children. We report the clinical and epidemiologic data of five nosocomial legionellosis cases that occurred in the Pediatric Nephrology Service between August, 1994, and December, 1998, and the control measures adopted. The Hospital Materno-Infantil Vall d'Hebron, Barcelona, is a 407-bed tertiary care hospital. The pediatric kidney transplant unit has three isolated beds in the same ward within the Pediatric Nephrology Service. Diagnostic workup to establish Legionella pneumophila infection included culture, fluorescent antibody and serologic studies. Macrorestriction analysis of genomic DNA was used as epidemiologic markers of the isolated strains. In May, 1996, a case of L. pneumophila serogroup 6 pneumonia was identified in a 19-year-old youth who had received a kidney transplant 16 days earlier. Retrospective and prospective analysis of legionellosis cases diagnosed at our center up to August, 1994, yielded four additional cases. Four patients had had a kidney transplant and were receiving immunosuppressive therapy, and the fifth had been diagnosed with systemic lupus erythematosus with renal involvement. L. pneumophila serogroup 6 was isolated in bronchial secretions in four cases; in the fifth patient the diagnosis was made by serology. L. pneumophila serogroup 6 was isolated from potable water of the hospital. Molecular epidemiologic methods revealed the identity of the environmental and clinical isolates. Showering was implicated as the most feasible means of exposure to contaminated water. Nosocomial legionellosis, albeit rare in children, should be considered in the differential diagnosis of pneumonias, particularly in immunosuppressed children, because the fatality rate may be high without early diagnosis and treatment.

The objective of this paper is to introduce a different approach, called the ecological-longitudinal, to carrying out pooled analysis in time series ecological studies. Because it gives a larger number of data points and, hence, increases the statistical power of the analysis, this approach, unlike conventional ones, allows the complementation of aspects such as accommodation of random effect models, of lags, of interaction between pollutants and between pollutants and meteorological variables, that are hardly implemented in conventional approaches. The approach is illustrated by providing quantitative estimates of the short-term effects of air pollution on mortality in three Spanish cities, Barcelona, Valencia and Vigo, for the period 1992-1994. Because the dependent variable was a count, a Poisson generalised linear model was first specified. Several modelling issues are worth mentioning. Firstly, because the relations between mortality and explanatory variables were non-linear, cubic splines were used for covariate control, leading to a generalised additive model, GAM. Secondly, the effects of the predictors on the response were allowed to occur with some lag. Thirdly, the residual autocorrelation, because of imperfect control, was controlled for by means of an autoregressive Poisson GAM. Finally, the longitudinal design demanded the consideration of the existence of individual heterogeneity, requiring the consideration of mixed models. The estimates of the relative risks obtained from the individual analyses varied across cities, particularly those associated with sulphur dioxide. The highest relative risks corresponded to black smoke in Valencia. These estimates were higher than those obtained from the ecological-longitudinal analysis. Relative risks estimated from this latter analysis were practically identical across cities, 1.00638 (95% confidence intervals 1.0002, 1.0011) for a black smoke increase of 10 microg/m(3) and 1.00415 (95% CI 1.0001, 1.0007) for a increase of 10 microg/m(3) of sulphur dioxide. Because the statistical power is higher than in the individual analysis more interactions were statistically significant, especially those among air pollutants and meteorological variables. Air pollutant levels were related to mortality in the three cities of the study, Barcelona, Valencia and Vigo. These results were consistent with similar studies in other cities, with other multicentric studies and coherent with both, previous individual, for each city, and multicentric studies for all three cities.

Objectives To estimate the prevalence of tobacco consumption and secondhand smoke (SHS) exposure in private cars, commercial vehicles and taxis in the city of Barcelona in Spain. Design setting and participants We carried out an observational cross-sectional study in 2011. We selected a systematic sample of 2442 private cars, commercial vehicles and taxis on 40 public roads regulated by traffic lights in all 10 districts of Barcelona. We calculated the prevalence rates and 95% CIs of smoking and SHS exposure in cars, and the corresponding ORs adjusting for the potential confounding variables. Results The prevalence of tobacco consumption was 5.5% (95% CI 4.6% to 6.4%) and was greater for commercial vehicles (9.8%; 95% CI 7.1% to 12.5%). The prevalence of SHS exposure was 5.2% (95% CI 3.8% to 6.6%) and 2.2% (95% CI 0.5% to 3.9%) of passengers under 14 years of age were exposed to SHS in vehicles. Conclusions This study highlights the need to promote public health measures aimed at reducing tobacco consumption in vehicles, especially in the presence of children, as well as enforcement of the current Spanish law against smoking in commercial vehicles and taxis.

Several studies have recognized the health disadvantage of residents in socioeconomically deprived neighborhoods, independent of the influence of individual socioeconomic conditions. The effect of neighborhood socioeconomic deprivation on general mortality has appeared heterogeneous among the cities analyzed: the underlying mechanisms have been less empirically explored, and explanations for this heterogeneous health effect remain unclear. The present study aimed to: (1) analyze the distribution of socioeconomically disadvantaged persons in neighborhoods of 4 European cities-Turin, Barcelona, Stockholm and Helsinki-trying to measure segregation of residents according to their socioeconomic conditions. Two measuring approaches were used, respectively, through dissimilarity index and clustering estimated from Bayesian models. (2) Analyze the distribution of mortality in the above mentioned cities, trying to disentangle the independent effects of both neighborhood socioeconomic deprivation and neighborhood segregation of residents according to their socioeconomic conditions, using multilevel models. A significantly higher risk of death was observed among residents in more deprived neighborhoods in all 4 cities considered, slightly heterogeneous across them. Poverty segregation appeared to be slightly associated with increasing mortality in Turin and, among females and only according to dissimilarity, in Barcelona. Few studies have explored the health effects of social clustering, and results could inform urban policy design with regard to social mix.

Evidence supports that gastric cancer has an environmental etiology, of which diet appears to be the most important component. The authors examined the effect of diet on the risk of gastric cancer. A case-control study of dietary factors and gastric cancer was conducted between September 1986 and March 1989 in the Barcelona metropolitan area, Spain. One hundred seventeen cases with histologically confirmed diagnosis of gastric adenocarcinoma were matched by age, gender, and whether they possessed a telephone to 234 community controls. One hundred eighty-eight (80.3%) controls were selected by random-digit telephone dialing and 46 (19.7%) by neighborhood of residence. Information about frequency and amount of consumption of 89 food items in one year was gathered by using a questionnaire, and cases and controls were interviewed in their homes by trained interviewers. Unconditional logistic regression was used for the analysis. Gastric cancer risk rose with increasing intake of smoked and pickled foods (OR 3.67 for upper tertile) and salt (OR 2.11 for upper quartile). Intake of citrus fruits (OR 0.47 for upper tertile) and raw-green vegetables (OR 0.56 for upper quartile) appeared to be protective. Gastric cancer risk was not associated with intake of cereals, rice, total vegetables, and fruits as a whole. These data suggest that high intake of salt and smoked and pickled food may be associated with a high risk of gastric cancer, and this association could be due to intragastric formation of nitrosamines.

Risk factors associated with asbestos-related diseases: a community-based case–control study

PubMed Central

2013-01-01

Background Asbestos is a first level carcinogen. However, few epidemiological studies analyse the risk and protective factors associated with asbestos-related diseases and follow up these conditions in the general population. Pleural mesothelioma, caused by inhalation of asbestos fibres at work, at home or in the environment, is the most representative asbestos-related disease. The objectives of this study are to analyse the risk and protective factors associated with asbestos-related diseases and to investigate the incidence of new clinical manifestations in patients already diagnosed with some form of ARD. Methods/Design We have designed a matched case–control study with follow up of both cohorts from a population of a health district of the Barcelona province that has been exposed to asbestos for a period of 90 years. Discussion A better understanding of asbestos-related diseases should improve i) the clinical and epidemiological follow up of patients with this condition; ii) the design of new treatment strategies; iii) and the development of preventive activities. At the end of the study, the two cohorts created in this study (affected cases and healthy controls) will constitute the basis for future research. PMID:23915043

Anastomotic leak (AL) increases costs and cancer recurrence. Studies show decreased AL with side-to-side stapled anastomosis (SSA), but none identify risk factors within SSAs. We hypothesized that stapler characteristics and closure technique of the common enterotomy affect AL rates. Retrospective review of bowel SSAs was performed. Data included stapler brand, staple line oversewing, and closure method (handsewn, HC; linear stapler [Barcelona technique], BT; transverse stapler, TX). Primary endpoint was AL. Statistical analysis included Fisher's test and logistic regression. 463 patients were identified, 58.5% BT, 21.2% HC, and 20.3% TX. Covidien staplers comprised 74.9%, Ethicon 18.1%. There were no differences between stapler types (Covidien 5.8%, Ethicon 6.0%). However, AL rates varied by common side closure (BT 3.7% vs. TX 10.6%, p = 0.017), remaining significant on multivariate analysis. Closure method of the common side impacts AL rates. Barcelona technique has fewer leaks than transverse stapled closure. Further prospective evaluation is recommended. Copyright © 2017. Published by Elsevier Inc.

Trypanosoma cruzi, the causative agent of Chagas disease, is divided into six Discrete Typing Units (DTUs): TcI-TcVI. We aimed to identify T. cruzi DTUs in Latin-American migrants in the Barcelona area (Spain) and to assess different molecular typing approaches for the characterization of T. cruzi genotypes. Seventy-five peripheral blood samples were analyzed by two real-time PCR methods (qPCR) based on satellite DNA (SatDNA) and kinetoplastid DNA (kDNA). The 20 samples testing positive in both methods, all belonging to Bolivian individuals, were submitted to DTU characterization using two PCR-based flowcharts: multiplex qPCR using TaqMan probes (MTq-PCR), and conventional PCR. These samples were also studied by sequencing the SatDNA and classified as type I (TcI/III), type II (TcII/IV) and type I/II hybrid (TcV/VI). Ten out of the 20 samples gave positive results in the flowcharts: TcV (5 samples), TcII/V/VI (3) and mixed infections by TcV plus TcII (1) and TcV plus TcII/VI (1). By SatDNA sequencing, we classified the 20 samples, 19 as type I/II and one as type I. The most frequent DTU identified by both flowcharts, and suggested by SatDNA sequencing in the remaining samples with low parasitic loads, TcV, is common in Bolivia and predominant in peripheral blood. The mixed infection by TcV-TcII was detected for the first time simultaneously in Bolivian migrants. PCR-based flowcharts are very useful to characterize DTUs during acute infection. SatDNA sequence analysis cannot discriminate T. cruzi populations at the level of a single DTU but it enabled us to increase the number of characterized cases in chronically infected patients.

Indoor and outdoor measurements of real-time ultrafine particles (UFP; N10-700 in this study) number concentration and average diameter were collected twice at 39 primary schools located in Barcelona (Spain), with classrooms naturally ventilated under warm weather conditions. Simultaneous outdoor N concentration measurements at schools under different traffic exposures showed the important role of this source, with higher levels by 40% on average at schools near heavy traffic, highlighting thus the increased exposure of children due to urban planning decisions. A well-defined spatial pattern of outdoor UFP levels was observed. Midday increases in outdoor N levels mainly attributed to nucleation processes have been recorded both at high and low temperatures in several of the outdoor school sites (increasing levels by 15%-70%). The variation of these increases also followed a characteristic spatial pattern, pointing at schools' location as a key variable in terms of UFP load owing to the important contribution of traffic emissions. Indoor N concentrations were to some extent explained by outdoor N concentrations during school hours, together with average temperatures, related with natural ventilation. Outdoor midday increases were generally mimicked by indoor N concentrations, especially under warm temperatures. At specific cases, indoor concentrations during midday were 30%-40% higher than outdoor. The time scale of these observations evidenced the possible role of: a) secondary particle formation enhanced by indoor precursors or conditions, maybe related with surface chemistry reactions mediated by O3, and/or b) UFP from cooking activities. Significant indoor N increases were detected after school hours, probably associated with cleaning activities, resulting in indoor N concentrations up to 3 times higher than those in outdoor. A wide variability of indoor/outdoor ratios of N concentrations and mean UFP sizes was detected among schools and measurement periods, which seems to be partly associated with climatic conditions and O3 levels, although further research is required.

Polychlorinated biphenyls (PCBs) are a class of aryl halides widely distributed in the environment. Although production has virtually ceased, and most industrial applications (capacitors, transformers, hydraulic fluids, lubricants, etc) are severely restricted, they are one of the most ubiquitous and persistent environmental pollutants. Several toxic effects caused by PCBs have been described including: liver enlargement, hepatomegalocytosis, acne, lymphoid atrophy, immunosuppression, tumor promotion, porphyria. This work continues the authors' previous reports about organochlorine residues in human tissues of some Spanish populations, that showed high levels of some residues, specially of hexachlorobenzene (HCB).

Most of the studies which demonstrate the existence of a short-term relationship between air pollution and morbidity and the Mortality analyze the impact of "classic" pollutants which are by-products of combustion. However, the changes in the sources of these emissions, shifting basically toward road traffic, has made a change in air pollution, heightening the importance of the photochemical components, such as ozone (O3) and nitrogen dioxide (NO2). Barcelona is a city located in a mild climate zone, and its air pollution comes mainly from vehicle emissions. The main objective of this article is that of analyzing the relationship between the photochemical pollutants, NO2 and O3 and the death rate for different causes in the city of Barcelona throughout the 1991-1995 period, using the procedure for analysis set out as part of the EMECAM Project. Daily changes in the number of deaths resulting from all causes, of the number of deaths for all causes of those over age 70, of the number of deaths resulting from cardiovascular diseases, and of the number of deaths resulting from respiratory-related causes are related to the daily changes in the photochemical pollutants using autoregressive Poisson models, controlling confusion-causing variables such as the temperature, the relative humidity, the systematic time structure and the autoregressive structure. Except for the relationship between O3 and the mortality for causes involving respiratory diseases, the relationships between photochemical pollutants and the mortality for all the causes considered were statistically significant. The risks related to dying as a result of rises in O3 were greater than as a result of rises in NO2, almost triple among cardiovascular diseases. The risks related to dying for all the causes are lower than for specific causes and than for those individuals over age 70. The results of the analysis by six-month periods are quite similar to the overall results, revealing, in any event, relative risks somewhat greater during the warm months (May to October). Photochemical pollution, especially that which is caused by O3, comprises a health risk. In the case of NO2, this might not be more than an indicators of the suspended particles or of other pollutants stemming from city traffic. There may be a certain adjustment between six-month periods of the impact of O3 on the mortality for causes of the circulatory system.

A study has been carried out to identify the origin of the odorous compounds at trace levels detected in surface waters and in Barcelona's tap water (NE Spain) which caused consumer complaints. The malodorous compounds were 2,5,5-trimethyl-1,3-dioxane (TMD) and 2-ethyl-5,5-dimethyl-1,3-dioxane (2EDD) which impart a distinctive sickening or olive-oil odor to drinking water at low ng/L levels. Flavor profile analysis (FPA) or threshold odor number (TON) were used for organoleptic purposes. Levels up to 749 ng/L for TMD and 658 ng/L for 2EDD were measured at the entrance of the drinking water treatment plant. Three wastewater treatment plants (WWTPs) using industrial byproducts coming from resin manufacturing plants to promote codigestion were found to be the origin of the event. Corrective measures were applied, including the prohibition to use these byproducts for codigestion in the WWTPs involved. A similar event was already recorded in the same area 20 years ago.

Community pharmacies (CP) have access to subjects at high-risk of suffering Chronic Obstructive Pulmonary Disease (COPD). We investigated if a COPD case finding program in CP could be a new strategy to reduce COPD underdiagnosis. Prospective, cross-sectional, descriptive, uncontrolled, remotely supported study in 100 CP in Barcelona, Spain. Pharmacists were trained in a four-day workshop on spirometry and COPD, and each was provided with a spirometer for 12 weeks. The program included questionnaires and forced spirometry measurements, whose quality was controlled and monitored by web-assistance. Overall 2295 (73.5%), of 3121 CP customers invited to participate in the program accepted, and 1.456 (63.4%) were identified as "high risk" for COPD using the GOLD questionnaire. Only 33 could not conduct spirometry, and a pre-bronchodilator airflow limitation (FEV1/FVC ratio <0.7) was confirmed in 282 (19.8%); 244 of these were referred to their primary care (PC) physician for further diagnostic and therapeutic work-up, but only 39 of them (16%) fed-back this information to the pharmacist. Clinically acceptable quality spirometries (grade A or B) were obtained in 69.4% of the cases. This study shows that adequately trained and supported community pharmacists can effectively identify individuals at high risk of having COPD and can thus contribute to ameliorate underdiagnosis in this disease. Links between PC and CP should be improved to achieve a useful program. Copyright © 2015 Elsevier Ltd. All rights reserved.

The XIII International AIDS Conference in Durban, South Africa in July 2000 focused worldwide attention on the problem of accessing treatments in developing countries. In the interim, thanks to the work of activists - from demonstrations to court cases, and from acts of public courage by people living with HIV/AIDS to ongoing lobbying of politicians and trade negotiators - some very significant developments have occurred. But the reality is that the vast majority of people living with HIV/AIDS still lack access to affordable, quality medicines. This article, a summary of a paper presented at "Putting Third First: Vaccines, Access to Treatments and the Law," a satellite meeting held at Barcelona on 5 July 2002 and organized by the Canadian HIV/AIDS Legal Network, the AIDS Law Project, South Africa, and the Lawyers Collective HIV/AIDS Unit, India, explores three approaches for improving access. In the first part, Richard Elliott provides an overview of the state of the right to health as embodied in international human rights law; comments on the experience to date in litigating claims to the right to health; and identifies potential strategies activists can adopt to advance recognition of the right to health. In the second part, Sharan Parmar and Vivek Divan describe price-control and drug-financing mechanisms used by industrialized countries to increase the affordability of medicines; and discuss how some of these mechanisms could be adapted for use in developing countries. Finally, Jonathan Berger describes the use of litigation in the courts by the Treatment Action Campaign in South Africa.

On the highly inclined vW leptokurtic asteroid families

NASA Astrophysics Data System (ADS)

Carruba, V.; Domingos, R. C.; Aljbaae, S.; Huaman, M.

2016-11-01

vW leptokurtic asteroid families are families for which the distribution of the normal component of the terminal ejection velocity field vW is characterized by a positive value of the γ2 Pearson kurtosis, I.e. they have a distribution with a more concentrated peak and larger tails than the Gaussian one. Currently, eight families are known to have γ2(vW) > 0.25. Among these, three are highly inclined asteroid families, the Hansa, Barcelona, and Gallia families. As observed for the case of the Astrid family, the leptokurtic inclination distribution seems to be caused by the interaction of these families with node secular resonances. In particular, the Hansa and Gallia family are crossed by the s - sV resonance with Vesta, that significantly alters the inclination of some of their members. In this work we use the time evolution of γ2(vW) for simulated families under the gravitational influence of all planets and the three most massive bodies in the main belt to assess the dynamical importance (or lack of) node secular resonances with Ceres, Vesta, and Pallas for the considered families, and to obtain independent constraints on the family ages. While secular resonances with massive bodies in the main belt do not significantly affect the dynamical evolution of the Barcelona family, they significantly increase the γ2(vW) values of the simulated Hansa and Gallia families. Current values of the γ2(vW) for the Gallia family are reached over the estimated family age only if secular resonances with Vesta are accounted for.

Endovascular aortic repair (EVAR) has been shown to be a valid and minimally invasive alternative to open abdominal aortic aneurysm repair. A major shortcoming for EVAR is the need to submit patients to regular follow-up to detect potential complications such as endoleak, limb occlusion, aneurysm expansion, aneurysm rupture, infection, structural failure, and migration. In this case report, we describe an uncommon case of late type III endoleak due to complete detachment of the stent-graft main body segment from its suprarenal uncovered fixation stent. It was treated with a custom-made Relay(®) NBS Plus (Bolton Medical, Barcelona, Spain) thoracic stent graft which also provided extra suprarenal fixation of the thoracic stent graft in the proximal neck. The postoperative period was uneventful and a computed tomography scan 1 year later revealed proper positioning of the stent graft and no signs of endoleak. The successful strategy chosen to correct this complication was at the same time original and infrequent, and also avoided potential complications related to open surgical repair and general anesthesia.

Patients with positive sputum smears are those with the capacity to spread infection. The objective of this study was to describe the incidence of tuberculosis in Catalonia (an autonomous community in the northeast of Spain which includes Barcelona) and to determine risk factors associated to patients with positive sputum smear test. New cases of tuberculosis detected by active surveillance between May 1996 and April 1997 were studied. The study was analysed as a coincident cases and controls study. The rate of incidence was calculated per 100,000 persons-year. The association of the dependent variable--case of tuberculosis with positive sputum smear--with the remainder of independent variables was determined by odds ratio (OR) with a 95% confidence interval (CI). A total of 2508 cases of tuberculosis were detected. The rate of incidence was 41.4 per 100,000 persons-year. Of these 19.4% (487/2508) were coinfected with HIV and 35.6% (893/2508) presented a positive sputum smear, which implies a rate of 14.7 per 100,000 persons-year. In an adjusted multivariate analysis, cases with positive smears were positively associated with the 15-24 (OR=1.9; 95% CI: 1.4-2.4), 25-34 (OR=2.1; 95% CI: 1.7-2.7) and 35-44 years (OR=1.7; 95% CI: 1.3-2.2) age compared with persons 45 years old and above; with males (OR=1.8; 95% CI: 1.5-2.2) and consumers of alcohol (OR=2.1; 95% CI: 1.7-2.7) and negatively with those under 15 years of age (OR=0.1; 95% CI: 0.1-0.2) and coinfection with HIV (OR=0.5; 95% CI: 0.3-0.7). Measures to control tuberculosis transmission (prompt diagnosis, study of contacts and directly observed treatments) should be reinforced for male adults with excessive consumption of alcohol.

Inherited genetic factors may modulate clinical outcome in melanoma. Some low-to-medium risk genes in melanoma susceptibility play a role in melanoma outcome. Our aim was to assess the role of the functional IRF4 SNP rs12203592 in melanoma prognosis in two independent sets (Barcelona, N = 493 and Essen, N = 438). Genotype association analyses showed that the IRF4 rs12203592 T allele increased the risk of dying from melanoma in both sets (Barcelona: odds ratio [OR] = 6.53, 95% CI 1.38-30.87, Adj p = 0.032; Essen: OR = 1.68, 95% CI 1.04-2.72, Adj p = 0.035). Survival analyses only showed significance for the Barcelona set (hazard ratio = 4.58, 95% CI 1.11-18.92, Adj p = 0.036). This SNP was also associated with tumour localization, increasing the risk of developing melanoma in head or neck (OR = 1.79, 95% CI 1.07-2.98, Adj p = 0.032) and protecting from developing melanoma in the trunk (OR = 0.59, 95% CI 0.41-0.85, Adj p = 0.004). These findings suggest for the first time that IRF4 rs12203592 plays a role in the modulation of melanoma outcome and confirms its contribution to the localization of the primary tumour. © 2017 UICC.

[The "plague" of Barcelona. Yellow fever epidemic of 1821].

Chastel, C

1999-12-01

The outbreak of yellow fever that struck Barcelona in 1821 followed a typical pattern for the times: a brick from Cuba introduced the disease in the port docks; the epidemic first reached the poor suburbs, and finally the center of the city. It was assumed that at least 20,000 inhabitants died from the scourge, that is a sixth of the total population of the city estimated 120,000. French authorities promptly took emergency measures at land and maritime borders by locking French ports to Catalan vessels and defining a quarantine line along the Pyrenean border controlled by an army 15,000 strong. French medical team including six physicians and two nuns was sent to Barcelona to provide assistance. Long after the epidemic had receded, the Pyrenean quarantine line was maintained by the French authorities for a hidden political purpose: Paris wished to contain Spanish Liberalism, a "revolutionary pest". French troops engaged in the so-called quarantine line were used in 1823 for invading the Spanish kingdom, while French physicians returning to Paris were celebrated as heroes and benefactors of the mankind although they had not provided any serious contribution to the therapeutics or the epidemiology of yellow fever. They were glorified in publications of the time without reserve. This unexpected manifestation of nationalism was welcomed and encouraged by the government of Louis XVIII who felt himself threatened by the liberal opposition.

To provide scientific evidence, using a literature review on psychosocial risk factors in mental health, that a high exposure to psychosocial stress situations in childhood increases the risk of mental disorders in adulthood,. A literature review up to December 2011 in the electronic databases from Medline, Universitat de Barcelona, and the Universitat Autonoma de Barcelona. The keywords used were: childhood, prenatal, vulnerability, risk, abuse, neglect, child mental disorder, schizophrenia, and prevention. Inclusion criteria for the studies reviewed: 1) designed to investigate childhood risk factors; 2) Comparative studies with persons without risk factors; 3) Studies with sufficient statistical significance; 4) Studies with "n" participants equal to o more than 30 persons. There are a group of easily identifiable mental health risk factors in childhood that can help in the prevention of mental disorders in the adulthood. They can be grouped into four categories: A) Pregnancy, birth and perinatal problems; B) Poor interpersonal relations with parents; C) Adverse life events in the first two years of life; D) Cognitive deficits in primary school, and social isolation during school years. There are life events that may increase the possibilities of suffering some kind of Psychopathology. It is necessary to consider those events as Risk Factors for Mental Health. The accumulation of these Risk Factors increases vulnerability to Mental Disorders. Copyright © 2013 Elsevier España, S.L.U. All rights reserved.

In a context of web application in the field of the dissemination of cultural heritage, this article advances in a methodology for the optimization of points clouds obtained through the technology of Laser Scanner (TLS). Identifying the potential of TLS surveys as interactive models that allow the cultural heritage to be perpetuated over time. This point cloud optimization is developed with free software, focusing its exploitation on an interactive web application, which has made it possible to convert two temporary museum exhibitions into permanent exhibitions in virtual format. Developed in conjunction with the Museu d’Història de la Ciutat de Barcelona. The case study focuses on the Palau Reial Major, Gothic style, formed by the chapel of Santa Àgata (built in 1302, on the Roman wall) and Saló del Tinell (built between 1359 and 1370, on the Roman remains). Located in the Plaça del Rei, in the old town of Barcelona. In this application is very important the visual impact, it requires to represent a faithful model of the interior of the building, from the point of view of color and lighting, avoiding the transparencies of the model through a dense cloud of dots, without occlusions, this requires a great quantity of positions. This implies a clear methodology, using different techniques such as photographic proyection, given the complexity of lighting of the building, as much for the artificial lighting as for the lighting of the stained glass. In this process, there were 84 positions that provide greater density of points, which are optimized with free programs. The temporary exhibitions of the case studies, elaborated by the MUHBA in the Saló del Tinell are: “Indianas, 1736-1847. The origins of industrial Barcelona” exposed from May 19, 2012 to March 3, 2013 and “El Món del 1714” exposed from December 20 to September 28, 2014. Both are based on a tour with showcases and exhibitors where different objects of a museum character are shown, such as looms, cloths, dresses, books, among others, accompanied by panels with texts and images that contain the information that each exhibition shows. Virtual applications allow such temporary exposures to become an interactive model, in which information can be permanently consulted. A virtual tour where the user can interact with the information panels and observe in detail the different objects of the exhibition. The results of this work manage to generate a powerful mechanism of diffusion and approximation to the society of the cultural heritage that, otherwise, as a whole as exhibition would disappear.

Malik, Amrita; Tauler, Roma

2015-06-01

This work focuses on understanding the behaviour and patterns of three atmospheric pollutants namely, nitric oxide (NO), nitrogen dioxide (NO2), and ozone (O3) along with their mutual interactions in the atmosphere of Barcelona, North Spain. Hourly samples were collected for NO, NO2 and O3 from the same city location for three consecutive years (2010-2012). The study explores the seasonal, annual and weekday-weekend variations in their diurnal profiles along with the possible identification of their source and mutual interactions in the region. Multivariate Curve Resolution-Alternating Least Squares (MCR-ALS) was applied to the individual datasets of these pollutants, as well as to all of them simultaneously (augmented mode) to resolve the profiles related to their source and variation patterns in the atmosphere. The analysis of the individual datasets confirmed the source pattern variations in the concerned pollutant's profiles; and the resolved profiles for augmented datasets suggested for the mutual interaction of the pollutants along with their patterns variations, simultaneously. The study suggests vehicular pollution as the major source of atmospheric nitrogen oxides and presence of weekend ozone effect in the region. Copyright © 2015 Elsevier B.V. All rights reserved.

Experiences with GOCE models in SONMICAT-BCN calibration site.

Martinez-Benjamin, J. J.; Termens, A.; Pros, F.

2016-12-01

SONMICAT - the integrated sea level observation system of Catalonia - aims at providing high-quality continous measurements of sea- and land levels at the Catalan coast from tide gauges and from modern geodetic techniques for studies on long-term sea level trends, but also the calibration of satellite altimeters, for instance. This synergy is indeed the only way to get a clear and unambigous picture of what is actually going on at the coast of Catalonia. Actually, there is a gap of sea level data in the coastal area of Catalonia, although several groups have started to do some work. SONMICAT will fill it and, as a goal, will be a regional implementation and densification of the GGOS . In the framework of SONMICAT project, the sea level infrastructure has been improved by providing the harbour of Barcelona with 3 tide gauges and a GPS station nearby. Furthermore, an airborne LiDAR campaign was carried out with two strips along two ICESat target tracks. The work focuses on the comparison between the GOCE gravity field solutions with existing local an regional gravity field models over the area of Barcelona harbour. The study will estimate how GOCE works on SONMICAT-BCN calibration site in order to prepare future geomatics issues .

Long-term exposure to benzene has been associated with several blood malignancies, including aplastic anemia, myeloproliferative neoplasms, and different leukemias. We present a case of primary myelofibrosis in a 59-year-old woman who worked as a cleaner at a car dealership and automobile mechanic shop. For 25 years, she used gasoline as a degreaser and solvent to clean engine parts, floors and work desks on a daily basis. She was referred by her primary care provider to the Occupational Health Unit of Barcelona to assess whether her illness was work-related. Review of her job history and working conditions revealed chronic exposure to benzene in the absence of adequate preventive measures. An association between benzene exposure and myeloproliferative disease was established, suspicious for an occupational disease. Copyright belongs to the Societat Catalana de Salut Laboral.

A Hypothesis: Could Portable Natural Grass be a Risk Factor for Knee Injuries?

PubMed Central

Orchard, John; Rodas, Gil; Til, Lluis; ArdevÒl, Jordi; Chivers, Ian

2008-01-01

Previous study has shown a likely link between increased shoe- surface traction and risk of knee Anterior Cruciate Ligament (ACL) injury. Portable natural grass systems are being used more often in sport, but no study to date has investigated their relative safety. By their nature, they must have high resistance to falling apart and therefore newly laid systems may be at risk of creating excessive shoe-surface traction. This study describes two clusters of knee injuries (particularly non-contact ACL injuries), each occurring to players of one professional football team at single venue, using portable grass, in a short space of time. The first series included two ACL injuries, one posterolateral complex disruption and one lateral ligament tear occurring in two rugby league games on a portable bermudagrass surface in Brisbane, Australia. The second series included four non-contact ACL injuries over a period of ten weeks in professional soccer games on a portable Kentucky bluegrass/perennial ryegrass surface in Barcelona, Spain. Possible intrinsic risk factors are discussed but there was no common risk shared by the players. Although no measures of traction were made at the Brisbane venue, average rotational traction was measured towards the end of the injury cluster at Camp Nou, Barcelona, to be 48 Nm. Chance undoubtedly had a part to play in these clusters, but the only obvious common risk factor was play on a portable natural grass surface soon after it was laid. Further study is required to determine whether portable natural grass systems may exhibit high shoe-surface traction soon after being laid and whether this could be a risk factor for knee injury. Key pointsExcessive shoe-surface traction is a hypothesised risk factor for knee ligament injuries, including anterior cruciate ligament injuries.Portable natural grass systems (by their nature in order to prevent grass rolls or squares from falling apart) will tend to exhibit high resistance to tearing when first laid. This may lead to excessive shoe-surface traction.This dual case series describes two clusters of non-contact knee ligament injuries which occurred in circumstances of newly laid portable turf.Further research is warranted to undercover any link between non-contact knee ligament injuries and ground surfaces conditions.

Ozone attributed to Madrid and Barcelona on-road transport emissions: Characterization of plume dynamics over the Iberian Peninsula.

PubMed

Valverde, Víctor; Pay, María T; Baldasano, José M

2016-02-01

Despite the ~30% emission decrease of the main tropospheric ozone (O3) precursors in Spain in the 2001-2012 period, the O3 concentration in summer still exceeds the target value for the protection of the human health of the Air Quality Directive (2008/50/EC). On-road transport is the main anthropogenic contributor to O3 precursor's emissions in Madrid and Barcelona metropolitan areas (65%/59% of NOx, 40%/33% of NMVOC, and 67%/85% of CO emissions) but this contribution to O3 formation is not well understood. The present work aims at increasing the understanding on the role of on-road transport emissions from main Spanish urban areas in O3 dynamics over Spain under typical circulation types. For that purpose, the Integrated Source Apportionment Method is used within the CALIOPE modelling system (WRF/CMAQ/HERMES/BSC-DREAM8b). The results indicate that the daily maximum O3 concentration attributed to the on-road transport emissions from Madrid (O3T-MAD) and Barcelona metropolitan areas (O3T-BCN) contribute up to 24% and 8% to total O3 concentration, respectively, within an area of influence of 200 km. The contribution of O3T-MAD and O3T-BCN is particularly significant (up to 80-100 μg m(-3) in an hour) to the O3 concentration peak during the central hours of the day in the high O3 concentration season (April-September). The maximum O3T-MAD concentration is calculated within the metropolitan area of Madrid but the plume, channelled by the Tajo and the Henares valleys, affects large areas of the Iberian Peninsula. The O3T-BCN plume is more driven by sea-land and mountain-valley breezes than by the synoptic advection and its maximum concentration is usually registered over the Mediterranean Sea. The O3 concentration transported long-range to the Iberian Peninsula is significant in the area of influence of Madrid and Barcelona, being maxima under cold (70-96%) and minima in warm circulation types (35-70%).

The presentation is directed to the description of the actual situation and relevant information of the geodetic infrastructure of Ibiza and Barcelona sites for sea level determination and contribution to regional sea level rise. Time series are being analysed for mean sea level variations www.puertos.es. .In the framework of a Spanish Space Project, the instrumentation of sea level measurements has been improved by providing the Barcelona site with a radar tide gauge Datamar 2000C from Geonica s.l. near an acoustic tide gauge. Puertos del Estado installed in 2007 a MIROS radar tide gauge and the Barcelona Harbour Authority a GPS referente station in the roof of the new Control Tower situated in the Energy Pier. The radar sensor is over the water surface, on a L-shaped structure which elevates it a few meters above the quay shelf. 1-min data are transmitted to the ENAGAS Control Center by cable and then sent each 1 min to Puertos del Estado by e-mail. There is a GPS station Leica Geosystems GRX1200 GG Pro and antenna 1202. Precision levelling has been made several times in the last two years because the tower is founded in reclaimed land. The measured settlement rate is about 1cm/year that may be could mask the values registered by the tide gauge. A description of the actual infrastructure at Ibiza harbour at Marina de Botafoch, is presented and its applications to sea level monitoring and altimeter calibration in support of the main CGPS at Ibiza harbour. It is described the geometrical precision levelling made in June 2013 between the radar tide gauge and the GPS station. In particular, the CGPS located at Ibiza harbour is essential for its application to the marine campaign Baleares 2013, near Ibiza island. The main objective is to determine the altimeter bias for Jason-2, about 9:09 UTC September 15, 2013, and Saral/AltiKa, about 05:30 UTC September 16, UTC.

Morphology and sediment dynamics of the northern Catalan continental shelf, northwestern Mediterranean Sea

The northern Catalan continental shelf, in the northwestern Mediterranean Sea, extends along 200 km from the Cap de Creus submarine canyon to the Llobregat Delta, in the vicinity of the city of Barcelona. In this paper we present the results of a systematic investigation of this area by means of very high-resolution multibeam bathymetry to fully assess its morphological variability. The causative factors and processes determining such variability are subsequently interpreted. The shelf is divided in three segments by two prominent submarine canyons: the northernmost Roses Shelf is separated from the intermediate La Planassa Shelf by the La Fonera Canyon, while the boundary between the La Planassa Shelf and the southernmost Barcelona Shelf is marked by the Blanes Canyon. These two canyons are deeply incised in the continental margin, with their heads located at only 0.8 and 5 km from the shore, respectively. The seafloor character reflects the influence of external controlling factors on the geomorphology and sediment dynamics of the northern continental shelf of Catalonia. These factors are the geological setting, the volume and nature of sediment input, and the type and characteristics of processes leading to sediment redistribution, such as dense shelf water cascading (DSWC) and eastern storms. The interaction of all these factors determines sediment dynamics and allows subdividing the northern Catalan continental shelf into three segments: the erosional-depositional Roses Shelf to the north, the non-depositional La Planassa Shelf in the middle, and the depositional Barcelona Shelf to the south. Erosional features off the Cap de Creus Peninsula and an along-shelf subdued channel in the outer shelf illustrate prevailing sediment dynamics in the Roses segment, which is dominated by erosional processes, local sediment accumulations and the southward bypass of sediment. The rocky character of the seafloor immediately north of the Blanes Canyon head demonstrates that neither significant sediment inputs from the Tordera River nor from the northern sources reach the southern part of the La Planassa Shelf. Palaeo-shorelines depict a number of paleodeltas with steep delta fronts on the drowned Barcelona Shelf.

The changes in the characteristics and needs in the cities structures means new challenges in the space to the economics activities. The increasing predominance of the tertiary industry, of offices or I+D buildings, like an effect of the economic transformation implies new forms, new technical characteristics and similar alternatives locations accordant with a changing demand. The project that is presented here, is developed by the Centre of Land Policy and Valuations of the University Polytechnic of Catalonia for the company "Servicios de Geo-marketing Inmobiliario S.L.' (SGMI, Real State Geo- marketing Services S.L.) The process consists in the generation of a geographic information system to the analyses of the characteristics office's buildings of Barcelona in the sense to introduce the property office's buildings of Barcelona into a database for the geo-marketing. This application allows the access to the necessary information of technical and constructive characteristics of the office's buildings, summoned by the most emblematic or central locations to the best technical level in their constructions towards facilitating the maximum knowledge the citizen in order to assure the choice according to the needs for every profile of demand. The work has consisted basically in defining the technical criteria of evaluation of the building, to systematize those characteristics in some indicators (variable) capable of expressing the level of quality of every variable, to establish a system measurement of greater to smaller value explained to the quality. Systematizing the collection of information of a total of 683 buildings of Barcelona and of some municipalities of its periphery, through a visit to every building, to process the data obtained to a database and to standardize the value of quality for every indicator and set of indicators towards determining a final qualification, obtained from the different physical, constructive and qualitative characteristics of every studied building. In the study and simulation of certain constructive parameters of the building the factor of location is very relevant, so that when relating the observed products, in their urban position, with the hierarchy agreed on of tertiary axes of the city, determining is possible in which measured the differential characteristics of those products, are adapted or not at the significance level of their urban site, and to determine forms of adequacy of the buildings placed in specific tertiary axes of the city, at the level that corresponds to him. The potency to anticipates the changes in the business models or the possibility to value the location profile, are very important aspects to the study the of the economic activities like an instrument to foresee relevant changes in the location and the level of requirement of technical evolution and services in the properties of biggest centrality. As final result factorial statistical measures that outline criteria of qualitative differentiation among the buildings studied, paying attention to urban areas are established. Competence ranges are determined, with regard to the quality of the buildings in comparable locations, and criteria are extracted about components being the most relevant in the choice and also the most singular.

Ultrafine particles are characterized by a high surface area per mass. Particle surface has been reported to play a significant role in determining the toxicological activity of ultrafine particles. In light of this potential role, the time variation of lung deposited surface area (LDSA) concentrations in the alveolar region was studied at the urban background environment of Barcelona (Spain), aiming to asses which processes and sources govern this parameter. Simultaneous data on Black Carbon (BC), total particle number (N) and particle number size distribution were correlated with LDSA. Average LDSA concentrations in Barcelona were 37 ± 26 μm(2)cm(-3), levels which seem to be characteristic for urban environments under traffic influence across Europe. Results confirm the comparability between LDSA data provided by the online monitor and those calculated based on particle size distributions (by SMPS), and reveal that LDSA concentrations are mainly influenced by particles in the size range 50-200 nm. A set of representative daily cycles for LDSA concentrations was obtained by means of a k-means cluster technique. The contribution of traffic emissions to daily patterns was evidenced in all the clusters, but was quantitatively different. Traffic events under stable atmospheric conditions increased mean hourly background LDSA concentrations up to 6 times, attaining levels higher than 200 μm(2)cm(-3). However, under warm and relatively clean atmospheric conditions, the traffic rush hour contribution to the daily LDSA mean appeared to be lower and the contribution of new urban particle formation events (by photochemically induced nucleation) was detected. These nucleation events were calculated to increase average background LDSA concentrations by 15-35% (maximum LDSA levels=45-50 μm(2)cm(-3)). Thereby, it may be concluded that in the urban background of Barcelona road traffic is the main source increasing the aerosol surface area which can deposit on critical regions of the human lung, followed by nucleation episodes.

This study aims to estimate the prevalence of oral halitosis in a young population and show the effect of chewing gum on their breath. Prospective, descriptive correlational cross section study. We selected a convenience sample of 121 young individuals and 98 completed the study. It was carried out at the University Dental Hospital-University of Barcelona. The protocol consisted of: questionnaire, oral clinical evaluation, organoleptic tests (OT) and measurement of volatile sulfur compounds (VSC) with sulphide monitoring before and after chewing gum during 15 min, with 2 calibrated investigators. A percentage of 87.8 had adequate oral hygiene, 17.3% reported bad breath and 29.6% had xerostomia. Forty-four subjects had a OT grade ≥2; the agreement of examiners was 75%. The VSC in 53 individuals were ≤100 parts per billion (ppb) and in 45 subjects, it was>100 ppb. A post-reduction of VSC of 17.34% was obtained with a mean decrease of 1.8-9.0 ppb (P=.003). The prevalence of halitosis was 36.7%. The use of chewing gum as an adjunct in cases of halitosis decreases the VSC, improving the perception of others and the patient.

To evaluate the prevalence of transmitted drug resistance (TDR) and non-B subtypes in patients with acute/recent HIV-1 infection in Barcelona during the period 1997-2012. Patients from the "Hospital Clínic Primary HIV-1 Infection Cohort" with a genotyping test performed within 180 days of infection were included. The 2009 WHO List of Mutations for Surveillance of Transmitted HIV-1 Drug Resistance was used for estimating the prevalence of TDR and phylogenetic analysis for subtype determination. 189 patients with acute/recent HIV-1 infection were analyzed in 4 time periods (1997-2000, n=28; 2001-4, n=42; 2005-8, n=55 and 2009-12, n=64). The proportion of patients with acute/recent HIV-1 infection with respect to the total of newly HIV-diagnosed patients in our center increased over the time and was 2.18%, 3.82%, 4.15% and 4.55% for the 4 periods, respectively (p=0.005). The global prevalence of TDR was 9%, or 17.9%, 9.5%, 3.6% and 9.4% by study period (p=0.2). The increase in the last period was driven by protease-inhibitor and nucleoside-reverse-transcriptase-inhibitor resistance mutations while non-nucleoside-reverse-transcriptase inhibitor TDR and TDR of more than one family decreased. The overall prevalence of non-B subtypes was 11.1%, or 0%, 4.8%, 9.1% and 20.3 by study period (p=0.01). B/F recombinants, B/G recombinants and subtype F emerged in the last period. We also noticed an increase in the number of immigrant patients (p=0.052). The proportion of men-who-have-sex-with-men (MSM) among patients with acute/recent HIV-1 infection increased over the time (p=0.04). The overall prevalence of TDR in patients with acute/recent HIV-1 infection in Barcelona was 9%, and it has stayed relatively stable in recent years. Non-B subtypes and immigrants proportions progressively increased.

Short-term variability of mineral dust, metals and carbon emission from road dust resuspension

Particulate matter (PM) pollution in cities has severe impact on morbidity and mortality of their population. In these cities, road dust resuspension contributes largely to PM and airborne heavy metals concentrations. However, the short-term variation of emission through resuspension is not well described in the air quality models, hampering a reliable description of air pollution and related health effects. In this study we experimentally show that the emission strength of resuspension varies widely among road dust components/sources. Our results offer the first experimental evidence of different emission rates for mineral dust, heavy metals and carbon fractions due to traffic-induced resuspension. Also, the same component (or source) recovers differently in a road in Barcelona (Spain) and a road in Utrecht (The Netherlands). This finding has important implications on atmospheric pollution modelling, mostly for mineral dust, heavy metals and carbon species. After rain events, recoveries were generally faster in Barcelona rather than in Utrecht. The largest difference was found for the mineral dust (Al, Si, Ca). Tyre wear particles (organic carbon and zinc) recovered faster than other road dust particles in both cities. The source apportionment of road dust mass provides useful information for air quality management.

Comparing meta-analysis and ecological-longitudinal analysis in time-series studies. A case study of the effects of air pollution on mortality in three Spanish cities

STUDY OBJECTIVE—The objective of this paper is to introduce a different approach, called the ecological-longitudinal, to carrying out pooled analysis in time series ecological studies. Because it gives a larger number of data points and, hence, increases the statistical power of the analysis, this approach, unlike conventional ones, allows the complementation of aspects such as accommodation of random effect models, of lags, of interaction between pollutants and between pollutants and meteorological variables, that are hardly implemented in conventional approaches.
DESIGN—The approach is illustrated by providing quantitative estimates of the short-term effects of air pollution on mortality in three Spanish cities, Barcelona, Valencia and Vigo, for the period 1992-1994. Because the dependent variable was a count, a Poisson generalised linear model was first specified. Several modelling issues are worth mentioning. Firstly, because the relations between mortality and explanatory variables were non-linear, cubic splines were used for covariate control, leading to a generalised additive model, GAM. Secondly, the effects of the predictors on the response were allowed to occur with some lag. Thirdly, the residual autocorrelation, because of imperfect control, was controlled for by means of an autoregressive Poisson GAM. Finally, the longitudinal design demanded the consideration of the existence of individual heterogeneity, requiring the consideration of mixed models.
MAIN RESULTS—The estimates of the relative risks obtained from the individual analyses varied across cities, particularly those associated with sulphur dioxide. The highest relative risks corresponded to black smoke in Valencia. These estimates were higher than those obtained from the ecological-longitudinal analysis. Relative risks estimated from this latter analysis were practically identical across cities, 1.00638 (95% confidence intervals 1.0002, 1.0011) for a black smoke increase of 10 µg/m3 and 1.00415 (95% CI 1.0001, 1.0007) for a increase of 10 µg/m3 of sulphur dioxide. Because the statistical power is higher than in the individual analysis more interactions were statistically significant, especially those among air pollutants and meteorological variables.
CONCLUSIONS—Air pollutant levels were related to mortality in the three cities of the study, Barcelona, Valencia and Vigo. These results were consistent with similar studies in other cities, with other multicentric studies and coherent with both, previous individual, for each city, and multicentric studies for all three cities.

The British Team at the 9th Paralympic Games in September 1992 in Barcelona comprised 151 men and 54 women athletes in a total of 15 sports. They were supported by a staff of 86 including a 12-strong medical team. The athletes were selected from the National Championships of the five disability organizations: British Wheelchair Sports Federation; British Blind Sport; Cerebral Palsy Sport; British Amputee Sports Association; and the British Les Autres Sports Association. This article outlines the organization and experience of the medical support team. The injury/illness profile was similar to those in able bodied sport. The team went on to achieve 40 gold, 47 silver and 41 bronze medals, maintaining third place on the medal table as achieved in Seoul in 1988.

to Describe perceived health, mental health and certain health-related behaviors according to sexual attraction and behavior in the population residing in Barcelona in 2011. Perceived health, mental health, chronic conditions and health-related behaviors were analyzed in 2675 people aged 15 to 64 years. The Barcelona Health Survey for 2011 was used, which included questions on sexual attraction and behavior. Multivariate robust Poisson regression models were fitted to obtain adjusted prevalence ratios. People feeling same-sex attraction reported a higher prevalence of worse perceived and mental health. These people and those who had had sex with persons of the same sex more frequently reported harmful health-related behaviors. Lesbian, gay, transgender and bisexual people may have health problems that should be explored in depth, prevented, and attended. Copyright © 2014 SESPAS. Published by Elsevier Espana.

Gerberto, gli Arabi e Gerusalemme

NASA Astrophysics Data System (ADS)

Sigismondi, C.

Gerbert of Aurillac went in Catalonia from 967 to 970, to visit the bishop Atton of Vic, famous for mathematical knowledge, during the apogee of Cordova's reign of the Caliph Al-Hakam II ibn Abd al-Rahman (961-976). He maintained contacts with local personalities like Mirò Bonfill (Bishop of Girona) and Lupitus of Barcelona through letters (both dated 984). When he was pope, Gerbert sent five papal privileges to Catalan dignitaries, showing his attention to this territory. The Caliph's prime minister Al-Mansu'r depredated Barcelona in 985, and conquered Santiago de Compostela in 997, drawing to an end the cultural exchanges between Christian and Arabic world through Mozarabic and Jewish translators. Gerbert learned and after taught and used Indo-Arabic numbers, abaci, astrolabes, monochords and theoretical music. It was possible for pilgrims to reach Jerusalem at Gerbert's times, and a letter written by Gerbert probably for an abbot starting his pilgrimage seems to introduce the first ideas of crusade and indulgences related to offers. The change of attitude of the Al-Andalus' government toward Christianity is probably responsible of these words written in a time very close to the depredations of Barcelona. Jerusalem is also in the index of geographic places in the book of the astrolabe, attributed to Gerbert, as well as Santiago de Compostela. Finally the legend of the Golem and the mass celebrated in the church of Jerusalem in Rome, completes the panorama of Gerbert and the Holy City.

To estimate the prevalence of moderate and vigorous physical activity (MVPA), as defined by the World Health Organisation (WHO), and associated factors among teenagers from Barcelona in 2012. Cross-sectional survey to assess risk factors in a representative sample of secondary school students (aged 13-16 years, International Standard Classification of Education [ISCED] 2, n=2,162; and 17-18 years, ISCED 3, n=1016) in Barcelona. We estimated MVPA prevalence overall, and for each independent variable and each gender. Poisson regression models with robust variance were fit to examine the factors associated with high-level MVPA, and obtained prevalence ratios (PR) and 95% confidence intervals (95%CI). Only 13% of ISCED 2 and 10% of ISCED 3 students met the WHO physical activity recommendations. This percentage was lower among girls at both academic levels. MVPA was lower among ISCED 3 compared to ISCED 2 students, and among students with a lower socioeconomic status. Physical activity was associated with positive self-perception of the health status (e.g., positive self-perception of health status among ISCED 2 compared to ISCED 3 students: PR=1.31 [95%CI: 1.22-1.41] and 1.61 [95%CI: 1.44-1.81] for boys and girls, respectively]. The percentage of teenagers who met WHO MVPA recommendations was low. Strategies are needed to increase MVPA levels, particularly in older girls, and students from low socioeconomic backgrounds.

To analyse the vaccination status of children diagnosed with pertussis and to compare the clinical manifestations of fully vaccinated with unvaccinated, or incompletely-vaccinated, children. The clinical histories and vaccination cards of patients under 16years of age seen in the Emergency Room of the University Hospital Vall d'Hebron, Barcelona (Spain), for pertussis confirmed by a microbiological study were reviewed. The study period lasted from January 1, 2009 to December 31, 2011. Two hundred and twelve cases were studied: 35 in 2009, 28 in 2010 and 149 in 2011. RT-PCR was positive in 210 patients, and 73 had a positive culture. Infants under 6months of age account for 36.8% of all cases. Forty-four patients (21.5%) were not vaccinated. Forty-four (21.5%) children were between 2 and 5months of age and had received 1-2vaccine doses. One hundred and seventeen (57%) children were fully vaccinated; 76.9% (90cases) had received the last dose less than 4years ago. When clinical manifestations of the fully vaccinated patients were compared with those of the non-vaccinated or incompletely-vaccinated children, only cyanosis was found with a higher frequency in the latter group (P<.001). The age-adjusted probability of hospitalisation was significantly associated with non-vaccination (P=.001). The case mortality rate among inpatients was 1.3%. The number of pertussis cases seen in our centre has risen significantly in the last year. More than half (57%) of the patients were fully vaccinated, and 76.9% had received the last dose in the previous 4years. Other vaccination strategies, such as vaccination of adolescents, adults, and pregnant women, as well as a cocoon strategy are required to protect infants under 6months of age. More effective vaccines need to be developed. Copyright © 2012 Elsevier España, S.L. y Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica. All rights reserved.

To find the individual and socio-family characteristics of that sector of the population which uses Primary Care Social Services (PCSS) at the Primary Care Centre (PCC) and the social problems which occasion demand. A retrospective descriptive study, based on checking over social work case files. A PCC situated in Barcelona's second industrial belt, serving a population with a low socio-economic level. The population group under study were the users with social work files open from January 1st 1985 to July 31st 1991 (a total of 690 case histories). A representative sample of 296 was selected. In comparison with the population of the basic Health Area, the user population of the PCSS at the PCC was predominantly women, and had an older average age, a higher proportion of divorce/separation and widowhood, and, in the labour context, higher unemployment and retirement. A high proportion of one-parent families (12.8%) was found. Analysis of the work situation showed that 50% of the workers were temporary and 75% of the unemployed received no benefit. 51% of the retired people received the minimum pension and 11% received no pension. Monthly family income, recorded for 46.5% of the cases, was 75,362 pesetas (SD 37,643). The most common problems were those related to the "HEALTH" section (61%). The user population of the PCSS at the PCC is, in socio-economic terms, deteriorated, a condition closely related to the development of chronic illnesses. Tackling health inequalities from Primary Care is under discussion.

Adolescents may present with adult-type pulmonary tuberculosis (TB), including cavity disease in upper lobes and smear-positive sputum, which involves a significant transmission risk for social and family contacts. A retrospective (2007-2012) observational study of a case series of TB was conducted in children and adolescents (<18 years) in a paediatric referral centre in Barcelona. Patients aged≤12 and>12 years at diagnosis are compared. The series consisted of 124 patients (56.5% males, median age: 4.0 years). In half of the cases, the patient was of immigrant origina and TB was diagnosed after clinical-radiological suspicion, intra-thoracic disease being the most common (91.9%). Cultures yielded positive results in one third of cases (37.9%) and isolates were sensitive to oral first-line anti-TB agents in 100%. Median (interquartile range) duration of treatment was 6 (6-9) months, directly observed therapy was needed in 10 patients, and there was a satisfactory outcome after treatment in 98.4%. Among adolescents, TB was more prevalent in females (63.2%) and immigrant patients (68.4%), comorbidity at diagnosis and lung cavity forms were more common, and the source case was identified only in 21.1% of the patients. Adult-type pulmonary TB is common among adolescents, may be associated with underlying medical conditions, and is often diagnosed late, posing a significant transmission risk to the community.

To investigate the value of fetal stomach position in predicting postnatal outcome in left-sided congenital diaphragmatic hernia (CDH) with and without fetoscopic endoluminal tracheal occlusion (FETO). This was a retrospective review of CDH cases that were expectantly managed or treated with FETO, assessed from May 2008 to October 2013, in which we graded, on a scale of 1-4, stomach position on the four-chamber view of the heart with respect to thoracic structures. Logistic regression analysis was used to investigate the effect of management center (Paris, Brussels, Barcelona, Milan), stomach grading, observed-to-expected lung area-to-head circumference ratio (O/E-LHR), gestational age at delivery, birth weight in expectantly managed CDH, gestational ages at FETO and at removal and period of tracheal occlusion, on postnatal survival in CDH cases treated with FETO. We identified 67 expectantly managed CDH cases and 47 CDH cases that were treated with FETO. In expectantly managed CDH, stomach position and O/E-LHR predicted postnatal survival independently. In CDH treated with FETO, stomach position and gestational age at delivery predicted postnatal survival independently. In left-sided CDH with or without FETO, stomach position is predictive of postnatal survival. Copyright © 2014 ISUOG. Published by John Wiley & Sons Ltd.

Whiplash injury (WI) is commonly evaluated in medico-legal practice. With the aim of knowing the determining factors of WI's medico-legal prognosis, a prospective and observational study was carried out. One hundred and twenty consecutive patients who were clinically observed and evaluated in the Medico-Legal Clinic of Barcelona were studied. Socio-demographic, clinical, radiographic and evolutive factors were analyzed. We included 120 patients with a mean age of 35.6 (14) years (range, 4-74), with a homogeneous male/female distribution. An earlier cervical pathology was detected in 10% of patients; none of them had previous psychiatric pathology. 95% corresponded to road-traffic accident cases and there were 5 aggression cases. Over 50% of cases involved a rear-end collision. All patients had neck pain, almost 25% had headache and 13% had paresthesia. According to the Whiplash Association Disorders clinical classification, distribution in grades (G) was: G I 51%, G II 32% and G III 17%. Patients reported recovery within a mean time of 71.6 (46) days (range, 4-244), with 51,2 (45) no working days (range, 0-180 days). The 52% of the patients rest with complains. According to the recovery time, the following medico-legal prognostic factors were identified: age (p < 0.001), being female (p = 0.001), clinical grade (p < 0.001) and abnormal cervical MRI exploration (p < 0.001). Patients with previous cervical pathology reported more complaints (p = 0.001). In our study, WI affected young people of both sex mainly during rear-end collision. Worst medico-legal prognostic factors were age, being females, severity of initial clinical symptoms, previous cervical pathology and abnormal cervical MRI/CT.

Molecular techniques and virus concentration methods have shown that previously unknown viruses are shed by humans and animals, and may be transmitted by sewage-contaminated water. In the present study, 10-L river-water samples from urban areas in Barcelona, Spain and Rio Janeiro, Brazil, have been analyzed to evaluate the viral dissemination of human viruses, validating also a low-cost concentration method for virus quantification in fresh water. Three viral groups were analyzed: (i) recently reported viruses, klassevirus (KV), asfarvirus-like virus (ASFLV), and the polyomaviruses Merkel cell (MCPyV), KI (KIPyV) and WU (WUPyV); (ii) the gastroenteritis agents noroviruses (NoV) and rotaviruses (RV); and (iii) the human fecal viral indicators in water, human adenoviruses (HAdV) and JC polyomaviruses (JCPyV). Virus detection was based on nested and quantitative PCR assays. For KV and ASFLV, nested PCR assays were developed for the present study. The method applied for virus concentration in fresh water samples is a one-step procedure based on a skimmed-milk flocculation procedure described previously for seawater. Using spiked river water samples, inter- and intra-laboratory assays showed a viral recovery rate of about 50% (20-95%) for HAdV, JCPyV, NoV and RV with a coefficient of variation ≤ 50%. HAdV and JCPyV were detected in 100% (12/12) of the river samples from Barcelona and Rio de Janeiro. Moreover, NoV GGII was detected in 83% (5/6) and MCPyV in 50% (3/6) of the samples from Barcelona, whereas none of the other viruses tested were detected. NoV GGII was detected in 33% (2/6), KV in 33% (2/6), ASFLV in 17% (1/6) and MCPyV in 50% (3/6) of the samples from Rio de Janeiro, whereas KIPyV and WUPyV were not detected. RV were only analyzed in Rio de Janeiro and resulted positive in 67% (4/6) of the samples. The procedure applied here to river water represents a useful, straightforward and cost-effective method that could be applied in routine water quality testing. The results of the assays expand our understanding of the global distribution of the viral pathogens studied here and their persistence in the environment. Copyright © 2013 Elsevier Ltd.

To report the anatomical pattern and etiological spectrum of uveitis in an urban multi-ethnic population from Barcelona, Spain. General and specific epidemiological data for the most prevalent aetiologies are also calculated. A cross-sectional study of consecutive uveitis cases was performed between 1 January 2009 and 31 December 2012. Exogenous endophthalmitis, surgery-related, post-traumatic and toxic uveitis along with masquerade syndromes were excluded. Anatomical (Standard Uveitis Nomenclature criteria) and aetiological patterns (by tailored tests), age, sex, geographical origin and laterality were analysed. Mean incidence and prevalence were calculated for a mid-period reference population. From 1022 patients included, 52% were anterior uveitis (AU), 23% posterior, 15% panuveitis and 9% intermediate uveitis. Aetiologically, 26% were unclassifiable, 29% infectious, 25% associated with systemic immune diseases, and 20% corresponded to ocular-specific syndromes. Among classified causes, herpesvirus (12%), toxoplasma (7%), Behçet's disease (BD) (5%), HLA-B27-isolated AU (5%), ankylosing spondylitis (5%), tuberculosis-related uveitis (TRU) (5%), birdshot chorioretinopathy (3%) and sarcoidosis (3%) were the most frequent. Non-Spanish origin was recorded in 22%, with 47% of Vogt-Koyanagi-Harada and 36% of toxoplasma cases coming from South America, 10% of BD and 11% of TRU from Africa and 24% of TRU cases from Asia. A mean annual incidence of 51.91 cases/100,000 inhabitants was found for the referral population. In our referral area, 74% of the uveitis cases can be correctly classified. A large myriad of uveitis aetiologies with a strong geographical origin burden are found in Western urban multi-ethnic populations. © 2015 Acta Ophthalmologica Scandinavica Foundation.

Diffusion in coastal and harbour zones, effects of Waves,Wind and Currents

NASA Astrophysics Data System (ADS)

Diez, M.; Redondo, J. M.

2009-04-01

As there are multiple processes at different scales that produce turbulent mixing in the ocean, thus giving a large variation of horizontal eddy diffusivities, we use a direct method to evaluate the influence of different ambient parameters such as wave height and wind on coastal dispersion. Measurements of the diffusivity are made by digital processing of images taken from from video recordings of the sea surface near the coast. The use of image analysis allows to estimate both spatial and temporal characteristics of wave fields, surface circulation and mixing in the surf zone, near Wave breakers and inside Harbours. The study of near-shore dispersion [1], with the added complexity of the interaction between wave fields, longshore currents, turbulence and beach morphology, needs detailed measurements of simple mixing processes to compare the respective influences of forcings at different scales. The measurements include simultaneous time series of waves, currents, wind velocities from the studied area. Cuantitative information from the video images is accomplished using the DigImage video processing system [3], and a frame grabber. The video may be controlled by the computer, allowing, remote control of the processing. Spectral analysis on the images has also used n order to estimate dominant wave periods as well as the dispersion relations of dominant instabilities. The measurements presented here consist mostly on the comarison of difussion coeficients measured by evaluating the spread of blobs of dye (milk) as well as by measuring the separation between different buoys released at the same time. We have used a techniques, developed by Bahia(1997), Diez(1998) and Bezerra(2000)[1-3] to study turbulent diffusion by means of digital processing of images taken from remote sensing and video recordings of the sea surface. The use of image analysis allows to measure variations of several decades in horizontal diffusivity values, the comparison of the diffusivities between different sites is not direct and a good understanding of the dominant mixing processes is needed. There is an increase of diffusivity with wave height but only for large Wave Reynolds numbers. Other important factors are wind speed and tidal currents. The horizontal diffusivity shows a marked anisotropy as a function of wave height and distance from the coast. The measurements were performed under a variety of weather conditions conditional sampling has been used to identify the different influences of the environmental agents on the actual effective horizontal diffusion[4].

Continuous measurements of surface mixed layer (SML), decoupled residual/convective layer (DRCL) and aerosol backscatter coefficient were performed within the Barcelona (Spain) boundary layer from September to October 2010 (30 days) in the framework of the SAPUSS (Solving Aerosol Problems by Using Synergistic Strategies) field campaign. Two near-infrared ceilometers (Jenoptik CHM15K), vertically and horizontally probing (only vertical profiles are herein discussed), were deployed. Ceilometer-based DRCLs (1761 ± 363 m a.g.l.) averaged over the campaign duration were twice as high as the mean SML (904 ± 273 m a.g.l.). Both DRCL and SML showed a marked SML diurnal cycle. Ceilometer data were compared with potential temperature profiles measured by daily radiosounding (twice a day, midnight and midday) to interpret the boundary layer structure in the coastal urban area of Barcelona. The overall agreement (R2 = 0.80) between the ceilometer-retrieved and radiosounding-based SML heights (h) revealed overestimation of the SML by the ceilometer (Δh=145 ± 145 m). After separating the data in accordance with different atmospheric scenarios, the lowest SML (736 ± 183 m) and DRCL (1573 ± 428 m) were recorded during warm North African (NAF) advected air mass. By contrast, higher SML and DRCL were observed during stagnant Regional (REG) (911 ± 234 m and 1769 ± 314 m, respectively) and cold Atlantic (ATL) (965 ± 222 m and 1878 ± 290 m, respectively) air masses. In addition to being the lowest, the SML during the NAF scenario frequently showed a flat upper boundary throughout the day possibly because of the strong winds from the Mediterranean Sea limiting the midday SML convective growth. The mean backscatter coefficients were calculated at two selected heights representative of middle and top SML portions, i.e. β500 = 0.59 ± 0.45 Mm-1 sr-1 and β800 = 0.87 ± 0.68 Mm-1 sr-1 at 500 m and 800 m a.g.l., respectively. The highest backscatter coefficients were observed during NAF (β500 = 0.77 ± 0.57 Mm-1 sr-1) when compared with ATL (β500 = 0.51 ± 0.44 Mm-1 sr-1) and REG (β500 = 0.64 ± 0.39 Mm-1 sr-1). The relationship between the vertical change in backscatter coefficient and atmospheric stability (∂θ/∂z) was investigated in the first 3000 m a.g.l., aiming to study how the unstable, stable or neutral atmospheric conditions of the atmosphere alter the distribution of aerosol backscatter with height over Barcelona. A positive correlation between unstable conditions and enhanced backscatter and vice versa was found.

The aim of this study is to test the effects of neo-Marxian social class and potential mediators such as labor market position, work organization, material deprivation, and health behaviors on all-cause mortality. The authors use longitudinal data from the Barcelona 2000 Health Interview Survey (N=7526), with follow-up interviews through the municipal census in 2008 (95.97% response rate). Using data on relations of property, organizational power, and education, the study groups social classes according to Wright's scheme: capitalists, petit bourgeoisie, managers, supervisors, and skilled, semi-skilled, and unskilled workers. Findings indicate that social class, measured as relations of control over productive assets, is an important predictor of mortality among working-class men but not women. Workers (hazard ratio = 1.60; 95% confidence interval, 1.10-2.35) but also managers and small employers had a higher risk of death compared with capitalists. The extensive use of conventional gradient measures of social stratification has neglected sociological measures of social class conceptualized as relations of control over productive assets. This concept is capable of explaining how social inequalities are generated. To confirm the protective effect of the capitalist class position and the "contradictory class location hypothesis," additional efforts are needed to properly measure class among low-level supervisors, capitalists, managers, and small employers.

Urban populations are growing and to accommodate these numbers, cities are becoming more involved in urban renewal programs to improve the physical, social and economic conditions in different areas. This paper explores some of the complexities surrounding the link between urban renewal, health and health inequalities using a theory-driven approach. We focus on an urban renewal initiative implemented in Barcelona, the Neighbourhoods Law, targeting Barcelona's (Spain) most deprived neighbourhoods. We present evidence from two studies on the health evaluation of the Neighbourhoods Law, while drawing from recent urban renewal literature, to follow a four-step process to develop a program theory. We then use two specific urban renewal interventions, the construction of a large central plaza and the repair of streets and sidewalks, to further examine this link. In order for urban renewal programs to affect health and health inequality, neighbours must use and adapt to the changes produced by the intervention. However, there exist barriers that can result in negative outcomes including factors such as accessibility, safety and security. This paper provides a different perspective to the field that is largely dominated by traditional quantitative studies that are not always able to address the complexities such interventions provide. Furthermore, the framework and discussions serve as a guide for future research, policy development and evaluation. Copyright © 2014 Elsevier Ltd. All rights reserved.

Climate change poses huge challenges for public health, and cities are at the forefront of this process. The purpose of this paper is to present the issues climate change poses for public health in the city of Barcelona, how they are being addressed, and what are the current major challenges, trying to contribute to the development of a baseline understanding of the status of adaptation in cities from a public health perspective. The major issues related to climate change faced by the city are common to other urban centers in a Mediterranean climate: heat waves, water availability and quality, air quality, and diseases transmitted by vectors, and all are reviewed in detail with empirical data. They are not a potential threat for the future, but have actually challenged the city services and infrastructure over the last years, requiring sustainable responses and rigorous planning. © The Author(s) 2016.

To determine the relative incidence of odontogenic cysts and to identify the main clinicopathological features among patients treated in the Oral Surgery Department of the Dental Clinic of the University of Barcelona (Spain). A retrospective observational study was made of 418 odontogenic cysts diagnosed in 380 patients included in the database of 1235 histopathological diagnoses. The subjects were treated in the Master degree program of Oral Surgery and Implantology of the University of Barcelona in the period 1997-2006. The following variables were recorded: gender, age, clinical characteristics of the lesions (size and location), radiological features, duration, treatment, complications and relapses. A descriptive analysis was made of the study variables, using the SPSS version 15.0. The incidence of odontogenic cysts was 33.8%. The mean patient age at appearance of the lesion was 42 years (range 7-83). The cysts were slightly more prevalent in males (58.4%). The lesion size ranged from 2-60 mm, with a mean size of 18.4 mm. The most frequent diagnosis was radicular cyst (50.2%). The most common location of the odontogenic cysts was in the mandible (61.5%), particularly the lower third molar region (36.8%). The most frequently diagnosed lesion was the radicular cyst. Odontogenic cysts were seen to be slightly more prevalent in males, and showed a high mandibular incidence. Knowledge of the biological and histological behavior of odontogenic cysts and their frequency are key aspects for ensuring early detection and adequate treatment.

A good communication plan is vital for optimal results in any screening programme. The objective of this study was to assess the knowledge, involvement and opinion of health professionals regarding the Breast Cancer Screening Programme in Barcelona in 2008. A cross-sectional study using an anonymous and self-administered questionnaire. The study population (N = 960) were health professionals from Primary Health-care (PH), Programs for Sexual and Reproductive Health (PSRH), and Community Pharmacies (CP). The dependent variables were: knowledge of the Programme, professional involvement and opinion of the Programme. The independent variables were: sex, age, qualifications, employment status, and health team. A descriptive and bivariate analysis was performed. Using multivariate logistic regression models adjusted for age, an Odds Ratios (OR) were obtained along with the 95% confidence intervals (CI 95%). PSRH professionals know the target population better; 80.2% versus 26.1% PH, and 14.0% CP, respectively. Professional involvement was related to the health care team (ORCP/PH: 0.32, CI 95%: 0.22-0.43) being observed more in PH. The opinion on the Programme in reducing breast cancer mortality was similar in the three teams (61.6% PH, 59.3% PSRH, and 56.5% CP). Healthcare professionals are unaware of some aspects of Programme, such as age range or periodicity. There is great professional involvement and belief that the Programme has helped disseminate information and knowledge on the early detection of breast cancer. Copyright © 2012 SECA.

After a rockfall event, a usual post event survey includes qualitative volume estimation, trajectory mapping and determination of departing zones. However, quantitative measurements are not usually made. Additional relevant quantitative information could be useful in determining the spatial occurrence of rockfall events and help us in quantifying their size. Seismic measurements could be suitable for detection purposes since they are non invasive methods and are relatively inexpensive. Moreover, seismic techniques could provide important information on rockfall size and location of impacts. On 14 February 2007 the Avalanche Group of the University of Barcelona obtained the seismic data generated by an artificially triggered rockfall event at the Montserrat massif (near Barcelona, Spain) carried out in order to purge a slope. Two 3 component seismic stations were deployed in the area about 200 m from the explosion point that triggered the rockfall. Seismic signals and video images were simultaneously obtained. The initial volume of the rockfall was estimated to be 75 m3 by laser scanner data analysis. After the explosion, dozens of boulders ranging from 10-4 to 5 m3 in volume impacted on the ground at different locations. The blocks fell down onto a terrace, 120 m below the release zone. The impact generated a small continuous mass movement composed of a mixture of rocks, sand and dust that ran down the slope and impacted on the road 60 m below. Time, time-frequency evolution and particle motion analysis of the seismic records and seismic energy estimation were performed. The results are as follows: 1 A rockfall event generates seismic signals with specific characteristics in the time domain; 2 the seismic signals generated by the mass movement show a time-frequency evolution different from that of other seismogenic sources (e.g. earthquakes, explosions or a single rock impact). This feature could be used for detection purposes; 3 particle motion plot analysis shows that the procedure to locate the rock impact using two stations is feasible; 4 The feasibility and validity of seismic methods for the detection of rockfall events, their localization and size determination are comfirmed.

Fifty million people are estimated to travel from industrial countries to the tropics annually. In spite of exhaustive studies and widely different diagnosis among returned patients, some cases of febrile illnesses remain without an etiological diagnosis, suggesting that these cases could be due to viral respiratory tract infections. From August 2005 to October 2006, 118 febrile patients without a specific diagnosis in their first visit at the Center for International Health of the Hospital Clínic of Barcelona were included. In all of them, in order to study respiratory viruses, a nasopharyngeal swab was collected. Clinical and radiological features and epidemiological data, as well as other samples for microbiologic studies, were also collected during consultation. Based on the physician's judgment at the time of consultation, patients were classified into four groups: respiratory symptoms (62%), febrile syndrome with nonspecific symptoms (24%), digestive symptoms (10%), and patients presenting both respiratory and digestive symptoms (4%). A pathogen microorganism was detected in 61 patients (52%). Respiratory viruses were detected in 44 out of 118 (37%) travelers included in the study, representing 56% of the patients with respiratory symptoms. The most frequently viruses detected were influenza virus (38%), rhinovirus (23%), adenovirus (9%), and respiratory syncytial virus (9%). Respiratory viruses have been shown to play an important role in imported fever. In light of the fact that international tourism is an increasing phenomenon, new strategies to prevent the spread of respiratory viruses should be considered, specially for influenza when a vaccine is available.

To determine the incidence of Streptococcus bovis (Sb) biotypes causing bacteraemia and associated malignancies. This is a retrospective analysis of patients with Sb bacteraemia, pulled out from a prospective surveillance protocol of bacteraemia cases, in three areas of Spain (1990-2013): a cattle area (Lugo), a fishing area (Ferrol) and an urban area (Barcelona). Colonoscopy and Sb biotypes (Sb-I and Sb-II) were determined in most cases. 506 patients with Sb bacteraemia; mean age 68.1 (±14.1) years, and 66.2% were males. The cattle area, compared with the fishing and urban areas, had higher incidence of bacteraemia by SbI (40.29 vs 9.38 vs 6.15 cases/10(6) person-years, P < 0.001) and bacteraemia by Sb-II (29.07 vs 9.84 vs 13.37 cases/10(6) person-years, P < 0.001). The Sb-I cases (n = 224), compared with Sb-II cases (n = 270), had greater rates of endocarditis (77.6% vs 9.6%, P < 0.001) and colorectal neoplasm (CRN) (50.9% vs 16.6%, P < 0.001), and smaller rates of biliary tract infection (2.2% vs 29.6%, P < 0.001) and non-colorectal malignancy (8.9% vs 31.4%, P < 0.001). There was a link between the cattle area and higher incidence of Sb bacteraemia. Sb-I differed from Sb-II cases in clinical findings and associated malignancies. Colonoscopy is mandatory in cases of endocarditis or bacteraemia caused by Sb-I. Copyright © 2015 The British Infection Association. Published by Elsevier Ltd. All rights reserved.

Human papillomavirus (HPV) has been reported in 12-82% of penile squamous cell carcinomas (SCC). There is an association of the virus with basaloid and warty carcinomas but the reported prevalence is variable. The causes of these variations are not clear. They may be owing to geographic differences, the use of different techniques to detect HPV, the status of the original paraffin blocks, or to variable criteria in tumor classification. The aims of the study were to determine the prevalence of HPV in penile SCC and subtypes using a sensitive technique, to investigate genotypes involved, and to search for other morphologic features associated with the virus from a series of cases from Paraguay. HPV detection was done by SPF-10 polymerase chain reaction followed by DNA enzyme-immunoassay and genotyping by LIPA 25 (version 1). Samples were tested at Catalan Institute of Oncology, Barcelona, and cross testing was carried out at the Delft Diagnostic Laboratories in The Netherlands. HPV was detected in 64 of 202 cases (32%). Thirteen tumors had multiple HPV genotypes. Most prevalent genotypes were HPV-16 (46 cases), HPV-6 (6 cases), and HPV-18 (4 cases), either in single or in multiple infections. HPV was preferentially associated with warty-basaloid (82%), basaloid (76%), and warty (39%) carcinomas and not detected in verrucous, mixed verrucous-papillary, pseudohyperplastic, and pseudoglandular SCCs. There was a strong association between HPV and higher histologic grade. Basaloid cells were more frequently found in HPV positive tumors (72%) and this association was statistically significant in univariate and multivariate analyses. Cells with koilocytotic features and keratinizing squamous cells were also present but to a much lesser degree (47% and 19%, respectively). In summary, HPV was found in a third of the cases and the most common genotype was HPV-16. Low-risk genotypes were rarely found in single infections, representing 4 cases among all analyzed (2%). There was an association between HPV presence and higher histologic grade and with basaloid, warty-basaloid, and warty carcinomas. Our results also suggest that, in penile SCC, the basaloid cell is the best tissue marker for oncogenic HPV infection.

Outdoor camera networks are becoming ubiquitous in critical urban areas of the largest cities around the world. Although current applications of camera networks are mostly tailored to video surveillance, recent research projects are exploiting their use to aid robotic systems in people-assisting tasks. Such systems require precise calibration of the internal and external parameters of the distributed camera network. Despite the fact that camera calibration has been an extensively studied topic, the development of practical methods for user-assisted calibration that minimize user intervention time and maximize precision still pose significant challenges. These camera systems have non-overlapping fields of view, are subject to environmental stress, and are likely to suffer frequent recalibration. In this paper, we propose the use of a 3D map covering the area to support the calibration process and develop an automated method that allows quick and precise calibration of a large camera network. We present two cases of study of the proposed calibration method: one is the calibration of the Barcelona Robot Lab camera network, which also includes direct mappings (homographies) between image coordinates and world points in the ground plane (walking areas) to support person and robot detection and localization algorithms. The second case consist of improving the GPS positioning of geo-tagged images taken with a mobile device in the Facultat de Matemàtiques i Estadística (FME) patio at the Universitat Politècnica de Catalunya (UPC).

Necrobiosis lipoidica (NL) is a chronic idiopathic granulomatous disease considered to occur in association with diabetes mellitus. Data on the frequency of this association, however, are inconsistent. Our aim was to retrospectively analyze the clinical characteristics of patients diagnosed with NL at our hospital and to investigate the association with diabetes mellitus and other diseases. We performed a chart review of all patients with a clinical and histologic diagnosis of NL treated and followed in the dermatology department of Hospital de Bellvitge in Barcelona, Spain between 1987 and 2013. Thirty-five patients (6 men and 29 women with a mean age of 47.20 years) were diagnosed with NL in the study period. At the time of diagnosis, 31 patients had pretibial lesions. Thirteen patients (37%) had a single lesion at diagnosis, and the mean number of lesions was 3.37. Twenty-three patients (65.71%) had diabetes mellitus (type 1 in 10 cases and type 2 in 13). In 20 patients, onset of diabetes preceded that of NL by a mean of 135.70 months. The 2 conditions were diagnosed simultaneously in 3 patients. None of the 35 patients developed diabetes mellitus during follow-up. Six patients had hypothyroidism, and 4 of these also had type 1 diabetes. NL is frequently associated with type 1 and 2 diabetes. Although diabetes tends to develop before NL, it can occur simultaneously. Copyright © 2014 Elsevier España, S.L.U. and AEDV. All rights reserved.

Potential uses of pumped urban groundwater: a case study in Sant Adrià del Besòs (Spain)

Jurado, Anna; Vázquez-Suñé, Enric; Pujades, Estanislao

2017-09-01

Urban groundwater has often been over-exploited for industrial uses. Now, this usage tends to be reduced or the resource abandoned due to pollution and/or changes in land use. The use and the subsequent disuse of groundwater has resulted in rising water tables that damage underground structures (e.g., building basements and underground car parks and tunnels), leading to the need for additional pumping in urban areas. In the case of the underground parking lot of Sant Adrià del Besòs (Barcelona, NE Spain), large amounts of urban groundwater are pumped to avoid seepage problems. Can this pumped groundwater be used for other purposes (e.g., drinking water and urban irrigation) instead of wasting this valuable resource? To answer this question, it was necessary to quantify the groundwater recharge and to assess the evolution of groundwater quality. The limiting factor at this study site is the groundwater quality because ammonium and some metals (iron and manganese) are present at high concentrations. Hence, further treatment would be needed to meet drinking water requirements. The pumped groundwater could also be used for supplementing river flow for ecological benefit and/or for mitigating seawater intrusion problems. Currently, only a small amount of this urban groundwater is used for cleaning public areas and watering public gardens. This situation highlighted the urgent need to manage this resource in a responsible and more efficient manner, especially in moments of high water demand such as drought periods.

Although analyses have been done on the publishing of scientific articles on pain in Spanish, book publications in the field have not been studied. This article fills that gap. A bibliography of books with pain approached from a medical standpoint was compiled from ISBN CD-ROM database (updated for 1993). Books going into more than one edition were considered single titles. Multi-volume collections were considered single books. We analyzed type of book, subject, ISBN classification, year, language (of publication and original), publisher and place of publication. Two hundred books were studied. Over 60% had been published within the previous 10 years. The year that showed the most books published was 1990 (19) followed by 1989 (16) and 1988 (16). Output has been rising steadily. One hundred ninety-eight books were published in Spanish and 2 in Catalan. The original language was Spanish in 114 cases, English in 51 cases, French in 21 and German in 7. By ISBN classification, most (146) covered pathology, disease and medical/therapeutic clinical practice. By topic, 51 books were general, 41 treated lumbalgia, sciatica or back pain and 35 covered headaches in general or migraine. Most of the books were issued by trade publishers. The cities most often involved were Barcelona and Madrid. An increased number of books about pain are being published in Spain, coinciding with a rise in the publication of scientific articles on the subject.

The importance of otorhinolaryngology as a separate branch of medicine has grown in the last decades. The objective of this work is to analyze the doctoral theses in ENT presented in Spain between 1976 and 2005. The TESEO database was searched for theses on otorhinolaryngology produced in Spain between 1976 and 2005. The search criteria used were the terms "Otorhinolaryngology," "Ear, nose, and throat surgery," "Hearing physiology," "Vestibular physiology," "Hearing physics," and "Bioacoustics". 468 theses were found (15.6 theses/year). Of these, 343 (73.6 %) were submitted by otorhinolaryngologists. The Universities of Valencia (Estudi General) (49), Complutense of Madrid (42), Salamanca (39), Barcelona (35), and Autònoma of Barcelona (31) accounted for most of the theses. The name of the supervisor was listed in 376 of the 468 theses (80.4 %); 286 of them had only 1 supervisor (76.1 %) and 90 had 2 (23.9 %). The most frequent topics were otology and audiology (35.1 %). Otorhinolaryngology in Spain has produced a similar number of theses as other areas of knowledge evaluated. The supervision of theses has tended to be shared in the most recent years studied. The number of theses submitted each year did not have only academic influences but also non-academic reasons.

Underground subways transport large numbers of citizens in big cities, which must breathe air with limited ventilation. These atmospheric conditions may enhance the concentration of air pollutants from both outdoor and indoor air. The influence of ventilation conditions and maintenance activities on the concentrations of air pollutants have been studied. Particulate matter with aerodynamic diameter smaller than 2.5 μm (PM 2.5 ) in indoor air was sampled in ten platforms of nine subway stations of the metropolitan area of Barcelona in 2015 and 2016. These particles were analyzed for polycyclic aromatic hydrocarbons (PAH) and organic tracer compounds. The concentrations of PAH were in the range of the street air levels with higher PAH values in the colder period. No influence of nighttime maintenance activities was observed on the platform air quality during daytime. Source apportionment analysis using the concentrations of hopanes, nicotine and levoglucosan as molecular tracer compounds showed that 75% of the detected PAH at the platforms have an outdoor PM origin. The modern subway stations, with advanced ventilation and platform screen doors that separate the subway system from the platform, showed lowest PAH and PM concentrations. Copyright © 2018.

Rumination syndrome is an uncommon gastrointestinal functional disorder that may be difficult to diagnose, as not many physicians are aware of this condition. In many cases, patients undergo numerous tests and are prescribed several treatments based on erroneous diagnoses. When the correct diagnosis is eventually made, therapy for the syndrome can be difficult and complex because of its multifactorial nature. The aim of this study was to present our experience with this condition, by presenting an analysis of the clinical, diagnostic, and therapeutic data of our patients. A prospective and retrospective study was conducted on all cases of rumination syndrome diagnosed between January 2010 and May 2016 in patients attending the Paediatric Gastroenterology Departments of two hospitals: Consorci Sanitari de Terrassa and Hospital Materno-Infantil Vall d'Hebron (Barcelona, Spain). The analysis included 12 patients, with a mean age at the onset of symptoms of 9 years and 1 month, and the mean time period to make the diagnosis was 2 years and 3 months. A mean of 8.1 complementary tests were carried out before establishing the diagnosis. In 10 of the 12 patients, some type of treatment had been given before the diagnosis of rumination syndrome, but was unsuccessful in all cases. Ten of our patients underwent the novel, experimental biofeedback therapy. Due to the limited knowledge of this condition among attending professionals in terms of the clinical presentation, diagnosis, and treatment, patients with rumination syndrome are often misdiagnosed and undergo numerous avoidable complementary tests, and invasive, costly treatments.

To describe drug-related problems identified in hospitalized patients and to assess physicians' acceptance rate of pharmacists' recommendations. Retrospective observational study that included all drug-related problems detected in hospitalized patients during 2014-2015. Statistical analysis included a descriptive analysis of the data and a multivariate logistic regression to evaluate the association between pharmacists' recommendation acceptance rate and the variable of interest. During the study period 4587 drug-related problems were identified in 44,870 hospitalized patients. Main drug-related problems were prescription errors due to incorrect use of the computerized physician order entry (18.1%), inappropriate drug-drug combination (13.3%) and dose adjustment by renal and/or hepatic function (11.5%). Acceptance rate of pharmacist therapy advice in evaluable cases was 81.0%. Medical versus surgical admitting department, specific types of intervention (addition of a new drug, drug discontinuation and correction of a prescription error) and oral communication of the recommendation were associated with a higher acceptance rate. The results of this study allow areas to be identified on which to implement optimization strategies. These include training courses for physicians on the computerized physician order entry, on drugs that need dose adjustment with renal impairment, and on relevant drug interactions.

Determining the natural history and predictors of survival in patients with untreated hepatocellular carcinoma (HCC) in the United States is useful to test existing tumor classifications, identify subgroups of patients likely to benefit from treatment, and estimate lead time related to HCC surveillance. We identified a national cohort of 518 veterans diagnosed with HCC from 2004 through 2011, with follow-up ending in 2014, who received no palliative or curative treatment. We examined the association between postdiagnosis survival and patient factors, tumor characteristics, and prediagnosis surveillance. The mean age at HCC diagnosis was 65.7 years and most patients had hepatitis C (60.6%). Almost all patients (99%) died within the observation period; the median overall survival time was 3.6 months and survival times were 13.4, 9.5, 3.4, and 1.6 months for patients of Barcelona Clinic Liver Cancer stages 0/A, B, C, and D, respectively. In addition, model for end-stage liver disease and levels of α-fetoprotein were predictive of survival. Nearly 28% received prediagnosis HCC surveillance, which was associated with detection of disease at an earlier stage (Barcelona Clinic Liver Cancer 0/A/B; 26.4% vs 14.4%; P = .0006) and slightly longer survival than patients with no surveillance overall (5.2 months vs 3.4 months; P = .021); there was no difference in survival times of patients with 0/A stage who did versus did not receive surveillance (10.3 months vs 10.5 months). Patients with HCCs, including those detected through surveillance, survived for short time periods in the absence of treatment, irrespective of their initial stage at diagnosis. Model for end-stage liver disease scores and levels of α-fetoprotein were prognostic factors, independent of Barcelona Clinic Liver Cancer stage. The lead time related to detection by surveillance was modest (<2 months) and therefore unlikely to explain the survival benefit associated with surveillance in previous studies.

ABSTRACT: BACKGROUND: The aim of this study was to assess the extent of knowledge of primary health care (PHC) patients about colorectal cancer (CRC), their attitudes toward population-based screening for this disease and gender differences in these respects. METHODS: A questionnaire-based survey of PHC patients in the Balearic Islands and some districts of the metropolitan area of Barcelona was conducted. Individuals between 50 and 69 years of age with no history of CRC were interviewed at their PHC centers. RESULTS: We analyzed the results of 625 questionnaires, 58% of which were completed by women. Most patients believed that cancer diagnosis before symptom onset improved the chance of survival. More women than men knew the main symptoms of CRC. A total of 88.8% of patients reported that they would perform the fecal occult blood test (FOBT) for CRC screening if so requested by PHC doctors or nurses. If the FOBT was positive and a colonoscopy was offered, 84.9% of participants indicated that they would undergo the procedure, and no significant difference by gender was apparent. Fear of having cancer was the main reason for performance of an FOBT, and also for not performing the FOBT, especially in women. Fear of pain was the main reason for not wishing to undergo colonoscopy. Factors associated with reluctance to perform the FOBT were: (i) the idea that that many forms of cancer can be prevented by exercise and, (ii) a reluctance to undergo colonoscopy if an FOBT was positive. Factors associated with reluctance to undergo colonoscopy were: (i) residence in Barcelona, (ii) ignorance of the fact that early diagnosis of CRC is associated with better prognosis, (iii) no previous history of colonoscopy, and (iv) no intention to perform the FOBT for CRC screening. CONCLUSION: We identified gaps in knowledge about CRC and prevention thereof in PHC patients from the Balearic Islands and the Barcelona region of Spain. If fears about CRC screening, and CRC per se, are addressed, and if it is emphasized that CRC is preventable, participation in CRC screening programs may improve.

Proponents of the biophilia hypothesis believe that contact with nature, including green spaces, has a crucial role in brain development in children. Currently, however, we are not aware of evidence linking such exposure with potential effects on brain structure. We determined whether lifelong exposure to residential surrounding greenness is associated with regional differences in brain volume based on 3-dimensional magnetic resonance imaging (3D MRI) among children attending primary school. We performed a series of analyses using data from a subcohort of 253 Barcelona schoolchildren from the Brain Development and Air Pollution Ultrafine Particles in School Children (BREATHE) project. We averaged satellite-based normalized difference vegetation index (NDVI) across 100-m buffers around all residential addresses since birth to estimate each participant's lifelong exposure to residential surrounding greenness, and we used high-resolution 3D MRIs of brain anatomy to identify regional differences in voxel-wise brain volume associated with greenness exposure. In addition, we performed a supporting substudy to identify regional differences in brain volume associated with measures of working memory ( d' from computerized n -back tests) and inattentiveness (hit reaction time standard error from the Attentional Network Task instrument) that were repeated four times over one year. We also performed a second supporting substudy to determine whether peak voxel tissue volumes in brain regions associated with residential greenness predicted cognitive function test scores. Lifelong exposure to greenness was positively associated with gray matter volume in the left and right prefrontal cortex and in the left premotor cortex and with white matter volume in the right prefrontal region, in the left premotor region, and in both cerebellar hemispheres. Some of these regions partly overlapped with regions associated with cognitive test scores (prefrontal cortex and cerebellar and premotor white matter), and peak volumes in these regions predicted better working memory and reduced inattentiveness. Our findings from a study population of urban schoolchildren in Barcelona require confirmation, but they suggest that being raised in greener neighborhoods may have beneficial effects on brain development and cognitive function. https://doi.org/10.1289/EHP1876.

Background: Green spaces have been associated with improved mental health in children; however, available epidemiological evidence on their impact on child behavioral development is scarce. Objectives: We investigated the impact of contact with green spaces and blue spaces (beaches) on indicators of behavioral development and symptoms of attention deficit/hyperactivity disorder (ADHD) in schoolchildren. Methods: This study was based on a sample of 2,111 schoolchildren (7–10 years of age) from 36 schools in Barcelona in 2012. We obtained data on time spent in green spaces and beaches and Strengths and Difficulties Questionnaires (SDQ) from parents, and ADHD/DSM-IV questionnaires from teachers. Surrounding greenness was abstracted as the average Normalized Difference Vegetation Index (NDVI) in buffers of 100 m, 250 m, and 500 m around each home address. Proximity to green spaces was defined as living within 300 m of a major green space (≥ 0.05 km2). We applied quasi-Poisson mixed-effects models (with school random effect) to separately estimate associations between indicators of contact with green spaces and SDQ and ADHD total and subscale scores. Results: We generally estimated beneficial associations between behavioral indicators and longer time spent in green spaces and beaches, and with residential surrounding greenness. Specifically, we found statistically significant inverse associations between green space playing time and SDQ total difficulties, emotional symptoms, and peer relationship problems; between residential surrounding greenness and SDQ total difficulties and hyperactivity/inattention and ADHD/DSM-IV total and inattention scores; and between annual beach attendance and SDQ total difficulties, peer relationship problems, and prosocial behavior. For proximity to major green spaces, the results were not conclusive. Conclusion: Our findings support beneficial impacts of contact with green and blue spaces on behavioral development in schoolchildren.

The existing information on oral rehabilitations with dental implants in VIH-positive patients is scarce and of poor quality. Moreover, no long-term follow-up studies are available. Hence, the aims of this study were to describe the long-term survival and success rates of dental implants in a group of HIV-positive patients and to identify the most common postoperative complications, including peri-implant diseases. A retrospective case series of HIV-positive subjects treated with dental implants at the School of Dentistry of the University of Barcelona (Spain) was studied. Several clinical parameters were registered, including CD4 cell count, viral load and surgical complications. Additionally, the patients were assessed for implant survival and success rates and for the prevalence of peri-implant diseases. A descriptive statistical analysis of the data was performed. Nine participants (57 implants) were included. The patients' median age was 42 years (IQR=13.5 years). The implant survival and success rates were 98.3% and 68.4%, respectively, with a mean follow-up of 77.5 months (SD=16.1 months). The patient-based prevalence of peri-implant mucositis and peri-implantitis were 22.2% and 44.4% respectively at the last appointment. Patients that attended regular periodontal maintenance visits had significantly less mean bone loss than non-compliant patients (1.3 mm and 3.9 mm respectively). Oral rehabilitation with dental implants in HIV-positive patients seems to provide satisfactory results. In order to reduce the considerably high prevalence of peri-implant diseases, strict maintenance programmes must be implemented.

Cities worldwide are increasingly becoming agents of climate change mitigation, while simultaneously aiming for other goals, such as improved accessibility and clean air. Based on stakeholder interviews and data analysis, we assess the current state of urban mobility in the four European cities of Barcelona, Malmö, Sofia and Freiburg. We then provide scenarios of increasingly ambitious policy packages, reducing greenhouse gas emissions from urban transport by up to 80% from 2010 to 2040. We find significant concurrent co-benefits in cleaner air, reduced noise ambience, fewer traffic-related injuries and deaths, more physical activity, less congestion and monetary fuel savings. Our scenarios suggest that non-motorized transport, especially bicycles, can occupy high modal shares, particularly in cities with less than 0.5 million inhabitants. We think that this kind of multi-criteria assessment of social costs and benefits is a useful complement to cost-benefit analysis of climate change mitigation measures.

Two scientific boreholes, Almera-1 and Almera-2 were drilled in the Barcelona University campus area in 2011. The main purpose for this drilling was to create a new geophysical logging and downhole monitoring research facility and infrastructure. We present results obtained in the frame of multidisciplinary studies and experiments carried out since 2011 at the ICTJA "Borehole Geophysical Logging Lab - Scientific Boreholes Almera" downhole lab facilities. First results obtained from the scientific drilling, coring and logging allowed us to characterize the urban subsurface geology and hydrology adjacent to the Institute of Earth Sciences Jaume Almera (ICTJA-CSIC) in Barcelona. The subsurface geology and structural picture has been completed with recent geophysical studies and monitoring results. The upper section of Almera-1 214m deep hole was cased with PVC after drilling and after the logging operations. An open hole interval was left from 112m to TD (Paleozoic section). Almera-2 drilling reached 46m and was cased also with PVC to 44m. Since completion of the drilling in 2011, both Almera-1 and Almera-2 have been extensively used for research purposes, tests, training, hydrological and geophysical monitoring. A complete set of geophysical logging measurements and borehole oriented images were acquired in open hole mode of the entire Almera-1 section. Open hole measurements included acoustic and optical imaging, spectral natural gamma ray, full wave acoustic logging, magnetic susceptibility, hydrochemical-temperature logs and fluid sampling. Through casing (PVC casing) measurements included spectral gamma ray logging, full wave sonic and acoustic televiewer. A Quaternary to Paleozoic section was characterized based on the geophysical logging and borehole images interpretation and also on the complete set of (wireline) cores of the entire section. Sample availability was intended for geological macro and micro-facies detailed characterization, mineralogical and petrophysical tests and analyses. The interpretation of the geophysical logging data and borehole oriented images, and core data allowed us to define the stratigraphy, structures and petrophysical properties in the subsurface. Quaternary sediments overlie unconformably weathered, deformed and partially metamorphosed Paleozoic rocks. A gap of the Tertiary rocks at the drillsite was detected. Structures at intensely fractured and faulted sections were measured and have yielded valuable data to understand the subsurface geology, hydrology and geological evolution in that area. Logging, borehole imaging and monitoring carried out in the scientific boreholes Almera-1 and Almera-2 has allowed also to identify three preferential groundwater flow paths in the subsurface. Geophysical logging data combined with groundwater monitoring allowed us to identify three zones of high permeability in the subsurface. Logging data combined with core analysis were used to characterize the aquifers lithology and their respective petrophysical properties. We also analyzed the aquifer dynamics and potential relationships between the variations in groundwater levels and the rainfalls by comparing the groundwater monitoring results and the rainfall. A seismic survey was carried out to outline the geological structures beyond Almera-1 borehole, a vertical reverse pseudo-3D (2.5D) seismic tomography experiment. The results allowed us to define the geological structure beyond the borehole wall and also a correlation between the different geological units in the borehole and their geometry and spatial geophysical and seismic image.

Despite the recent progress in treatment options, malignant melanoma remains a deadly disease. Besides therapy, inherited factors might modulate clinical outcome, explaining in part widely varying survival rates. T-cell effector function regulators on antitumor immune responses could also influence survival. CD5, a T-cell receptor inhibitory molecule, contributes to the modulation of antimelanoma immune responses as deduced from genetically-modified mouse models. The CD5 SNPs rs2241002 (NM_014207.3:c.671C>T, p.Pro224Leu) and rs2229177 (NM_014207.3:c.1412C>T, p.Ala471Val) constitute an ancestral haplotype (Pro224-Ala471) that confers T-cell hyper-responsiveness and worsens clinical autoimmune outcome. The assessment of these SNPs on survival impact from two melanoma patient cohorts (Barcelona, N=493 and Essen, N=216) reveals that p.Ala471 correlates with a better outcome (OR= 0.57, 95% CI=0.33-0.99, Adj. P=0.043, in Barcelona OR=0.63, 95% CI=0.40-1.01, Adj. P=0.051, in Essen). While, p.Leu224 was associated with increased melanoma-associated mortality in both cohorts (OR=1.87, 95% CI=1.07-3.24, Adj. P=0.030 in Barcelona and OR=1.84, 95% CI=1.04-3.26, Adj. P=0.037, in Essen). Furthermore survival analyses showed that the Pro224-Ala471 haplotype in homozygosis improved melanoma survival in the entire set of patients (HR=0.27, 95% CI 0.11 to 0.67, Adj. P=0.005). These findings highlight the relevance of genetic variability in immune-related genes for clinical outcome in melanoma. PMID:27169428

An artificial neural network (ANN) was developed and tested to forecast PM10 daily concentration in two contrasted environments in NE Spain, a regional background site (Montseny), and an urban background site (Barcelona-CSIC), which was highly influenced by vehicular emissions. In order to predict 24-h average PM10 concentrations, the artificial neural network previously developed by Caselli et al. (2009) was improved by using hourly PM concentrations and deterministic factors such as a Saharan dust alert. In particular, the model input data for prediction were the hourly PM10 concentrations 1-day in advance, local meteorological data and information about air masses origin. The forecasted performance indexes for both sites were calculated and they showed better results for the regional background site in Montseny (R(2)=0.86, SI=0.75) than for urban site in Barcelona (R(2)=0.73, SI=0.58), influenced by local and sometimes unexpected sources. Moreover, a sensitivity analysis conducted to understand the importance of the different variables included among the input data, showed that local meteorology and air masses origin are key factors in the model forecasts. This result explains the reason for the improvement of ANN's forecasting performance at the Montseny site with respect to the Barcelona site. Moreover, the artificial neural network developed in this work could prove useful to predict PM10 concentrations, especially, at regional background sites such as those on the Mediterranean Basin which are primarily affected by long-range transports. Hence, the artificial neural network presented here could be a powerful tool for obtaining real time information on air quality status and could aid stakeholders in their development of cost-effective control strategies. © 2013 Elsevier B.V.

UPC BarcelonaTech Platform. Innovative aerobatic parabolic flights for life sciences experiments.

NASA Astrophysics Data System (ADS)

Perez-Poch, Antoni; Gonzalez, Daniel

We present an innovative method of performing parabolic flights with aerobatic single-engine planes. A parabolic platform has been established in Sabadell Airport (Barcelona, Spain) to provide an infraestructure ready to allow Life Sciences reduced gravity experiments to be conducted in parabolic flights. Test flights have demonstrated that up to 8 seconds of reduced gravity can be achieved by using a two-seat CAP10B aircraft, with a gravity range between 0.1 and 0.01g in the three axis. A parabolic flight campaign may be implemented with a significant reduction in budget compared to conventional parabolic flight campaigns, and with a very short time-to-access to the platform. Operational skills and proficiency of the pilot controling the aircraft during the maneuvre, sensitivity to wind gusts, and aircraft balance are the key issues that make a parabola successful. Efforts are focused on improving the total “zero-g” time and the quality of reduced gravity achieved, as well as providing more space for experiments. We report results of test flights that have been conducted in order to optimize the quality and total microgravity time. A computer sofware has been developed and implemented to help the pilot optimize his or her performance. Finally, we summarize the life science experiments that have been conducted in this platform. Specific focus is given to the very successful 'Barcelona ZeroG Challenge', this year in its third edition. This educational contest gives undergraduate and graduate students worldwide the opportunity to design their research within our platform and test it on flight, thus becoming real researchers. We conclude that aerobatic parabolic flights have proven to be a safe, unexpensive and reliable way to conduct life sciences reduced gravity experiments.

In this study, the simultaneous presence of eight polybrominated diphenyl ethers (PBDEs), nine new brominated flame retardants (NBFRs) and ten organophosphorus flame retardants (OPFRs) was investigated in dust samples collected from different indoor environments (homes, schools, theatres, a university and a Research Institute) in Barcelona, Spain. OPFRs were detected at the highest concentrations followed by PBDEs. ∑OPFRs ranged from 2053 to 72,090ngg(-1) and tris(2-chloroisopropyl) phosphate (TCIPP) was the most abundant compound. BDE-209 was the main PBDE congener detected (up to 14,990ngg(-1)), while other PBDEs ranged from 2.6 to 118ngg(-1). Among the studied NBFRs, decabromodiphenyl ethane (DBDPE - up to 4432ngg(-1)) followed by bis(2-ethylhexyl) tetrabromophthalate (BEH-TEBP - up to 508ngg(-1)) were detected at the highest concentration, whereas a lower detection frequency was observed for 2-ethylhexyl 2,3,4,5-tetrabromobenzoate (EH-TBB), 1,2-bis(2,4,6-tribromophenoxy)ethane (BTBPE), pentabromotoluene (PBT) and hexabromobenzene (HBB). The levels and profile of flame retardants (FRs) were characteristic of each environment, where theatres followed by homes presented the highest concentrations and schools had the lowest levels. Principal Component Analysis permitted to identify the main sources and distribution of all FRs, according to specific uses in each environment. The simultaneous presence of all FR families in indoor dust points to the need to monitor these compounds to minimize human exposure. Copyright © 2016 Elsevier Inc. All rights reserved.

Studies of the prevalence of HIV in sentinel populations are one of the key strategies to monitor the HIV epidemic. We describe HIV prevalence trends and identify differences across time in the sociodemographic characteristics of HIV-infected women giving birth in Catalonia. We used dried blood specimens, residual to newborn screening, which have been collected in Catalonia every 2 months since 1994. The total number of samples obtained until 2009 and in 2013 represented half of yearly newborns. From 2010 to 2012, the total number of samples obtained represented a quarter of yearly newborns. We studied the prevalence by year and place of current residence (Barcelona-city, cities>200,000 inhabitants and cities ≤ 200,000 inhabitants) and by the mother's birth country. A total of 624,912 infants were tested for HIV antibodies from January 1994 to December 2013. HIV prevalence trends among women giving birth in Catalonia decreased until 2007. Thereafter, there was a change to a steady trend until 2013. However, among foreign women giving birth and living in cities ≤ 200,000 inhabitants, the prevalence of HIV increased from 2007 to 2013. To ensure early identification and treatment of HIV-infected mothers, it is essential to maintain HIV surveillance programs and pre- and post-natal screening programs, both in Barcelona and in cities with 200,000 inhabitants or less, especially in immigrant women.

The purpose of this study was to evaluate the prevalence of sarcopenia in a cohort of healthy community-dwelling elderly in an urban area in Barcelona (Spain) for native benchmarks and compare them with those published in other geographical areas. We prospectively evaluated a series of 200 healthy elderly in the community with preserved functional capacity and absence of cognitive impairment. We performed a comprehensive geriatric assessment and determined anthropometric data, muscle mass (MM) and the muscle mass index (MMI). Assessment of muscle mass was performed by bioelectrical impedance analysis (BIA). The cut-off point for defining sarcopenia MMI was established as less than 2 SD of the mean of a reference group comprising 220 healthy volunteers (20-42 years) in the same area. Results were compared with studies undertaken in the USA, France and Taiwan. The cut-off points obtained were 8.31 Kg/m(2) for men and 6.68 Kg/m2 for women, being similar to those observed in France and Taiwan but different from the USA. The prevalence of sarcopenia observed was 33% for elderly women and 10% for males. On comparison of the prevalence of sarcopenia in the four populations, we observed some differences, particularly in males. We have defined reference values for sarcopenia, determined by BIA, in our setting. We also observed a remarkable prevalence of sarcopenia in the healthy elderly community, especially in females, showing some differences from those in other geographical regions.

The aim of this study was to analyze the rate of incidence, clinical presentation, serotype, and clonal distribution of invasive pneumococcal disease (IPD) in the era of heptavalent pneumococcal conjugate vaccine (PCV7) in Barcelona, Spain. This was a prospective study comprising all children <5 years with IPD who were managed in 2 tertiary-care, pediatric hospitals between January 2007 and December 2009. IPD was defined as the presence of clinical findings of infection together with isolation or detection of DNA of Streptococcus pneumoniae in a sterile fluid sample. In this study, 319 patients (53.3% male), mean age 29.6 months, were included. Comparing rates in 2007 and 2009 (76.2 and 109.9 episodes/100,000 population, respectively), an increase of 44% (95% confidence interval, 10%-89%) was observed. The main clinical presentation was pneumonia (254 episodes, 79.6%), followed by meningitis (29, 9.1%), and bacteremia (25, 7.8%).The diagnosis was made by positive culture in 123 (38.6%) patients and in 196 (61.4%) by real-time polymerase chain reaction. Serotype study was performed in 300 episodes, and 273 (91%) were non-PCV7 serotypes. The most frequent serotypes were 1 (20.7%), 19A (15.7%), and 3 (12.3%). A minimal inhibitory concentration ≥0.12 μg/mL to penicillin was detected in 34.4% of isolates. Sequence type 306 expressing serotype 1 was the most frequent clonal type detected (20.3% of studied strains). IPD continues to increase in Barcelona, and the rate is higher than previously reported as a result of low sensitivity of bacterial culture. Non-PCV7 serotypes were responsible for 91% of episodes and pneumonia was the main clinical presentation.

To describe needs and experiences of mothers with children under one year old, to identify the factors that hinder the transition to motherhood, and to design the content of a health promotion program to develop motherhood support group sessions. A qualitative study with a phenomenological approach. Eight Primary Care Centres in the province of Barcelona, between July 2011 and July 2012. A total of 21 mothers participating in group dynamics maternity support: All of them participated in interviews and 8 in focus group. Semi-structured interviews were used in a purposive sample. The transcriptions were analysed by structure (latent content analysis) and content (manifest content analysis), with different categories being obtained. The participants in the study defined the construct of motherhood around three categories: Changes in lifestyle, feelings and perceptions. They identified as the most stressful times; «the new role», «changes in the partner relationship», «feelings», «experiences of pregnancy and childbirth», «idealisation», «lack of support», «crying», «colic», «read the signs of the child», «bath», «rest», «contradictory opinions», «learning», and «acquisition of new skills». They highlighted, as key topics for group dynamics, feeding, development, affective relationship, maternal confidence, fathers participation, family role, emotional, rest, massage, bath, accident prevention, colic, first aid, childcare, resources, and vaccines. Dynamic groups should be contextualised according to the perceived needs of the mothers, and other family members should be allowed to participate. Copyright © 2012 Elsevier España, S.L.

To know the family environment, living habits and social characteristics in 11-13 years-old school children. A descriptive transversal study performed in 65 schools of Barcelona during the second three-month, involving 2354 school children aged 11-13 interviewed by 73 pharmacists. The questionnaire has thirty-nine questions referring to family structure, eating and drinking habits, preferences, life style parameters such as physical activity and television viewing. The survey revealed a family unit of two children and their parents was the most common. Only a 12% of the children surveyed lived with their grandparents. Furthermore, the findings revealed a low family presence during the three main meals on the working days, which increased on weekends, 26% on breakfast, 44% on lunch and 11% on dinner. A 24% had breakfast alone and the 46% ate what they wanted. About the afternoon snack, the 25% alone and the 55% what they wanted. A 60% never or practically never participated in decision making, when buying food. A 70% reported they did other activities while eating. Concretely, a 40, 39 and 59% of the children reported they had breakfast, lunch and dinner while watching television. The consumption frequency of trinkets, soft drinks and television viewing were lower for the children from private compared to public schools. This study show that food choice at shopping was mainly done by the parents, however, children had an important role in making decisions of what food they eat and the activities they do while eating. Therefore, pharmacists could have a potential role to intervene in the nutritional education to parents and children.

Masana, E.; Ribas, S. J.; Jordi, C.; Gómez, V.

The Department of Astronomy and Meteorology (DAM) of the University of Barcelona organized the I Workshop on Science and Astronomy for Youth in November 2007, with the title The Sun: Radiation and Gravitation, as one of its outreach activities for high school students. About 350 participants took part in four different activities during the Workshop. On one hand, some days before the beginning of the activities, some DAM members went to the different high schools to present the sessions and introduce some key concepts to follow them. On the other hand, during their visit to the facilities of the Physics Faculty and the Astronomy Department of the University of Barcelona, they took part in: an observation of the Sun looking at sunspots, and a short lecture on safety rules on Sun's observations and on the Sun's structure and activity; a lecture with the title Why do stars shine?; and a computer experience named Gravitation: Kepler's 3rd Law.

Bravo, L; Ferrer, I

2011-01-01

Life Cycle Assessment was used to evaluate environmental impacts associated to a full-scale wastewater treatment plant (WWTP) in Barcelona Metropolitan Area, with a treatment capacity of 2 million population equivalent, focussing on energy aspects and resources consumption. The wastewater line includes conventional pre-treatment, primary settler, activated sludge with nitrogen removal, and tertiary treatment; and the sludge line consists of thickening, anaerobic digestion, cogeneration, dewatering and thermal drying. Real site data were preferably included in the inventory. Environmental impacts of the resulting impact categories were determined by the CLM 2 baseline method. According to the results, the combustion of natural gas in the cogeneration engine is responsible for the main impact on Climate Change and Depletion of Abiotic Resources, while the combustion of biogas in the cogeneration unit accounts for a minor part. The results suggest that the environmental performance of the WWTP would be enhanced by increasing biogas production through improved anaerobic digestion of sewage sludge.

The present paper presents the occurrence of 72 pharmaceuticals and 23 transformation products (TPs) in groundwaters (GWs) underlying the city of Barcelona, Spain. Thirty-one samples were collected under different districts, and at different depths. Aquifers with different geologic features and source of recharge were included, i.e., natural bank filtration, infiltration from wastewater and water supply pipes, rainfall recharge, etc. Antibiotics were the most frequently found compounds detected at levels reaching 1000 ng L(-1). Natural bank filtration from the river that receives large amounts of effluents from waste water treatment plants (WWTPs), turned out being the most influencing source of contamination, thus GW showed high range of compounds and concentrations as high as or even higher than in the river itself. In general, TPs were found at lower concentrations than the corresponding parent compounds, with some exceptions, such as 4OH propranolol and enalaprilat. Copyright © 2012 Elsevier Ltd.

The creation of the European Higher Education Area has brought the relevance of the scientific quality assessment in higher education. The result of this interest is a growing interest in the development of rankings of universities, both nationally and internationally. To continue the line started two years ago, the goal of this research is to update the ranking of research productivity in Spanish public universities with the data of 2010. We follow the same methodology to data from 2008 and 2009; although this year it includes measures of total production. The same indicators to evaluate research in 2009: journals articles indexed in the JCR, research periods, research + development projects, doctoral dissertations, grants for training university teachers, Doctoral Programs with Quality Mention and patents. From the results obtained show that universities with higher production were Complutense de Madrid, Barcelona and Granada. The most productive were the Pompeu Fabra University, the Pablo de Olavide, and the Autonoma de Barcelona.

Escherichia coli early-onset sepsis (EOS) is an important cause of mortality and morbidity in neonates, especially in preterm and very low birth weight (VLBW) newborns. The aim of our study was to evaluate potential changes in the clinical and microbiological characteristics of E. coli EOS in our setting. Epidemiological, clinical, and microbiological data from all neonates with proven E. coli EOS from January 1994 to December 2014 were retrospectively collected in a single tertiary care hospital in Barcelona (Spain). Seventy-eight E. coli EOS cases were analyzed. A slight increase in the incidence of E. coli EOS was observed during the study period. VLBW newborns remained the group with higher incidence (10.4 cases per 1000 live births) and mortality (35.3%). Systematic use of PCR increased E. coli EOS diagnosis, mainly in the term newborn group. There was an increase in resistant E. coli strains causing EOS, with especially high resistance to ampicillin and gentamicin (92.8 and 28.6%, respectively). Nonetheless, resistant strains were not associated with poorer clinical outcomes. There is an urgent need to reconsider the empirical therapy used in neonatal EOS, particularly in VLBW newborns. What is Known: • E. coli early-onset sepsis (EOS) and E. coli resistant strains have been described as overall stable but increasing in VLBW neonates (< 1.500 g) in previous studies. What is New: • Our study shows an increasing incidence of E. coli EOS in all age groups, overruling group B Streptoccocus for the last 10 years. E. coli resistant strains also increased equally in all age groups, with high resistance rates to our first line antibiotics (ampicillin and gentamicin). • Empiric antibiotic therapy of EOS, mainly in VLBW newborns, should be adapted to this new scenario.

Barcelona's Continuing Immunization Plan affords the possibility Of monitoring the immunization coverage of the population by means of the voluntary family postal notification system. Prior studies have revealed that some families fail to provide notification while being correctly vaccinated, which can lead to actual coverage being underestimated. The objectives of this study are to estimate the early childhood immunization coverage of the population and to ascertain the factors associated with failure to provide notification of immunization. A phone survey was conducted on a sample of 500 children regarding whom there was no record of any notification of the first three childhood vaccine doses (diphtheria, tetanus, whooping cough and oral polio), in addition to a sample of 500 children who were on record as having been immunized. To estimate the actual immunization coverage, all children were considered to have been properly immunized when their family members did provide notification. As regards those who failed to reply, it was considered in the worst of cases that these were cases of children who had not be immunized. In the best of cases scenario, a coverage similar to those of the responses was assumed. The response to the questionnaire was higher among those who had previously provided notification of immunization by way of the postal notification system (79.1%) than among those who had failed to provide notification of immunization (67%). The leading factors associated with failure to report immunization status were the size of the families, the use of private health care services and the place of birth of the parents. Solely six (6) cases of those who had failed to report immunization admitted to not having immunized their children, totaling 1.9% of the responses. The immunization coverage of the population in question would total 99.7% in the best of cases and 93.7% in the worst of cases scenario. Immunization coverage of the population in question is quite high. The results underline the importance of promoting immunization notification among health care professionals, especially in the private sector.

Sánchez-Gárces, María Angeles; Gay-Escoda, Cosme

2004-01-01

Orodental rehabilitation through the use of implants offers very high success rates. In this paper, we describe some of the complications involved with this technique, such as periimplant disease and, within this category, periimplantitis, an inflammatory reaction in which there is a loss of the bony support of the implant accompanied by inflammation. The aetiology of the disease is conditioned by the status of the tissue surrounding the implant, implant design, degree of roughness, the poor alignment of implant components, external morphology and excessive mechanical load. The microorganisms most commonly associated with implant failure are spirochetes and mobile forms of Gram-negative anaerobes, unless the origin is the result of simple mechanical overload. Diagnosis is based on changes of colour in the gum, bleeding and probing depth of periimplant pockets, suppuration, x-ray and gradual loss of bone height around the tooth. Treatment will differ depending upon whether it is a case of mucositis or periimplantitis. Therapeutic objectives focus on correcting technical defects by means of surgery and decontamination techniques (abrasion with carbon particles, citric acid solution, topical tetracycline application and laser surgery). This study also presents a microbiological study of periimplantitis conducted by the Barcelona School of Dentistry that determined that the antibiotic therapy proven to be most efficacious in the antibiogram was the association of amoxycillin and clavulanic acid.

Soil Organic Carbon assessment on two different forest management. A.F. Minguillón1, T. Sauras1, V.R: Vallejo1. 1 Departamento de Biología Evolutiva, Ecología y Ciencias Ambientales, Universidad de Barcelona, Avenida Diagonal 643, 03080 Barcelona, Spain. Soils from arid and semiarid zones are characterized by a low organic matter content from scarce plant biomass and it has been proposed that these soils have a big capacity to carbon sequestration. According to IPCC ARS WG2 (2014) report and WG3 draft, increase carbon storage in terrestrial ecosystems has been identified such a potential tool for mitigation and adaptation to climate change. In ecological restoration context improve carbon sequestration is considered a management option with multiple benefits (win-win-win). Our work aims to analyze how the recently developed restoration techniques contributed to increases in terrestial ecosystem carbon storage. Two restoration techniques carried out in the last years have been evaluated. The study was carried out in 6 localities in Valencian Community (E Spain) and organic horizons of two different restoration techniques were evaluated; slash brush and thinning Aleppo pine stands. For each technique, carbon stock and its physical and chemical stability has been analysed. Preliminary results point out restoration zones acts as carbon sink due to (1) the relevant necromass input produced by slash brush increases C stock on the topsoil ;(2) Thinning increase carbon accumulation in vegetation.

The transport of Glyphosate ([N-phosphonomethyl] glycine), AMPA (aminomethylphosphonic acid, CH(6)NO(3)P), and Bromide (Br(-)) has been studied, in the Mediterranean Maresme area of Spain, north of Barcelona, where groundwater is located at a depth of 5.5m. The unsaturated zone of weathered - granite soils was characterized in adjacent irrigated and non-irrigated experimental plots where 11 and 10 boreholes were drilled, respectively. At the non irrigated plot, the first half of the period was affected by a persistent and intense rainfall. After 69 days of application residues of Glyphosate up to 73.6 microgg(-1) were detected till a depth of 0.5m under irrigated conditions, AMPA, analyzed only in the irrigated plot was detected till a depth of 0.5m. According to the retardation coefficient of Glyphosate as compared to that of Br(-) for the topsoil and subsoil (80 and 83, respectively) and the maximum observed migration depth of Br(-) (2.9 m) Glyphosate and AMPA should have been detected till a depth of 0.05 m only. Such migration could be related to the low content of organic matter and clays in the soils; recharge generated by irrigation and heavy rain, and possible preferential solute transport and/or colloidal mediated transport.

The identification of disaster victims is the formal, organized process of identifying multiple bodies after an incident with multiple victims. The appropriate management of these incidents, particularly of the bodies, is one of the most crucial aspects of disaster response and its importance has led to the evolution of the concept of Disaster Victim Management. The aim of this study is to report how the process of identifying the 12 mortal victims of a railway accident in June 2010 in Castelldefels (Barcelona) was managed. The methodology used complied with the National Protocol for medical forensic and scientific police response to mass casualty incidents. The family assistance center also served as an ante mortem (AM) office. Despite the fragmentation of the bodies, all the victims were identified satisfactorily. The main problems observed during the management of the disaster were due to the state of the bodies, which raised many doubts as to the number of fatalities. The experience prompted a proposal to establish some recommendations on limiting the number of fragments to be analyzed genetically. We would like to stress the importance of setting up a Data Integration Center which brought together all the participating institutions, and collected and supervised all the different identification reports in a single comprehensive text addressed to the competent legal authority.

The high frequency of criminal behaviour and related legal problems associated with substance addiction generates a field of interaction between legal and healthcare systems. This study was developed as a multicentre project to investigate the opinions of professionals from legal and healthcare systems about policies on illegal drugs and their implementation in practice. A multiple choice questionnaire designed ad hoc was administered to a sample of 230 professionals from legal and healthcare fields working in the cities of Barcelona, Granada and Bilbao. The questionnaire included sociodemographic and work-related data, and assessed interviewees' information about the response to drug-related crime and opinion on drug policy issues. This article presents the results from Spain. The main results showed that both groups of professionals value alternative measures to imprisonment (AMI) as useful tools to prevent offenses related to drug use and claim a broader application of AMI. They also evaluated positively the regulations on cannabis use in effect. Though the attitude of healthcare professionals towards the application of AMI is more permissive, both groups favour restricting these sanctions in cases of recidivism. Both groups show mild satisfaction with the current addiction healthcare system and express dissatisfaction with actual drug policies in Spain.

Rocky-shore communities as indicators of water quality: a case study in the Northwestern Mediterranean.

The collection of 152 samples from the upper sublittoral zone along the rocky coasts of Catalonia (Northwestern Mediterranean) was carried out in 1999 in order to test the suitability of littoral communities to be used as indicators of water quality in the frame of the European Water Framework Directive. Detrended correspondence analysis were performed to distinguish between different communities and to relate communities composition to water quality. Samples collected in reference sites were included in the analysis. Mediterranean rocky shore communities situated in the upper sublittoral zone can be used as indicators of the water quality: there is a gradient from high to bad status that comprises from dense Cystoseira mediterranea forests to green algae dominated communities. The geographical patterns in the distribution of these communities show that the best areas are situated in the Northern coast, where tourism is the main economic resource of the area, and the worst area is situated close to the metropolitan zone of Barcelona with high population and industrial development. Thus, Mediterranean sublittoral rocky shore communities are useful indicators of water quality and multivariate analysis are a suitable statistical tool for the assessment of the ecological status.

The importance of hypersensitivity to fungal allergens is a relatively unknown and somewhat controversial subject. An open prospective study was carried out in just one centre to determine the clinical and epidemiological characteristics as well as the diagnostic usefulness of skin prick and conjunctiva provocation tests, associated with total and specific IgE determination in two groups of patients, one of which was monosensitised to fungi and the other of which had multiple sensitisations, including fungi. Rhinitis, exclusive or associated with asthma, was the main consultation cause (88% in monosensitised patients). Severe asthma was rarely found. In the polysensitised group, 64% were simultaneously allergic to moulds and mites. Alternaria alternata was the most common sensitising fungus, although a considerable number of cases were associated with other species such as Cladosporium, Penicillium and/or Aspergillus. The skin prick test gave the highest sensitivity and specificity. In 67% of the cases, the specific IgE was found between classes 3 and 4. The conjunctival provocation test was an innocuous and highly useful method for verifying the diagnosis and determining the degree of clinical sensitisation. A large number of patients exclusively allergic to fungi received specific immunotherapy, and it was generally well tolerated. This protocolised study shows the importance of Alternaria and other fungi sensitisations in rhinitis alone or associated with asthma. Combined diagnosis of prick test, specific IgE and conjunctiva provocation test is very useful for deciding specific immunotherapy. Copyright © 2011 SEICAP. Published by Elsevier Espana.

High resolution model mesh and 3D printing of the Gaudí’s Porta del Drac

2017-10-01

This article intends to explore the limits of scanning with the technology of 3D Laser Scanner and the 3D printing, as an approximation to its application for the survey and the study of singular elements of the architectural heritage. The case study we developed is the Porta del Drac, in the Pavelló Güell, designed by Antoni Gaudí. We divided the process in two parts, one about how to scan and optimize the survey with the Laser Scanner Technology, made with a Faro Forus3D x330 scanner. The second one, about the optimization of the survey as a high-resolution mesh to have a scaled 3D model to be printed in 3D, for the musealization of the Verdaguer House of Literature in Vil.la Joana (Barcelona), a project developed by the Museum of History of Barcelona, in tribute to Jacint Verdaguer. In the first place, we propose a methodology for the survey of this atypical model, which is of special interest for several factors: the geometric complexity in relation to the occlusions, the thickness of the metallic surfaces, the hidden internal structure partially seen from the outside, the produced noise in its interior, and the instrumental errors. These factors make the survey process complex from the data collection, having to perform several scans from different positions to cover the entire sculpture, which has a geometry composed of a variety of folds that cause occlusions. Also, the union of the positions and the average of the surfaces is of great relevance, since the elements of the sculpture are constructed by a metal plate of 2mm, therefore, the error in the union of all these many positions must be smaller than this. Moreover, optimization of the cloud has a great difficulty because of the noise created by the instrumental error as it is a metal sculpture and because of noise point clouds that are generated inside the internal folds of the wings, which are made with a welded wire mesh with little spaces between them. Finally, the added difficulty that there is an internal structure between elements of the parts of the Drac that are partially hidden and therefore cannot be recorded. Secondly, we expose the procedures performed to move from a point cloud to an optimal high-resolution mesh to be printed in 3D, adapting it to all the limitations that this printing technique entails. On the one hand, for the meshing process, a previous classification of the point cloud by pieces (wings, chains, mosaics, head …) is made and an internal structure is re-assembled to avoid floating parts. On the other hand, the selection of the 3D printing technique, in this case FDM (Fused Deposition Modelling), limits the size of the model so it needs to be cut by determined maximum dimension, and also it limits the minimum thickness of the model’s surface, that is to say, the model cannot be directly scaled to the desired size because the 2mm surfaces would be too thin to be printed. This research intends to advance the knowledge of data acquisition, optimization, modelling and 3D printing, with a case study of great complexity. A process that can be systematized and applied to other models.

The 13-valent pneumococcal conjugate vaccine (PCV13) was licensed based on the results of immunogenicity studies and correlates of protection derived from randomized clinical trials of the 7-valent conjugate pneumococcal vaccine. We assessed the vaccination effectiveness (VE) of the PCV13 in preventing invasive pneumococcal disease (IPD) in children aged 7-59 months in a population with suboptimal vaccination coverage of 55%. The study was carried out in children with IPD admitted to three hospitals in Barcelona (Spain) and controls matched by hospital, age, sex, date of hospitalization and underlying disease. Information on the vaccination status was obtained from written medical records. Conditional logistic regression was made to estimate the adjusted VE and 95% confidence intervals (CI). 169 cases and 645 controls were included. The overall VE of ≥1 doses of PCV13 in preventing IPD due to vaccine serotypes was 75.8% (95% CI, 54.1-87.2) and 90% (95% CI, 63.9-97.2) when ≥2 doses before 12 months, two doses on or after 12 months or one dose on or after 24 months, were administered. The VE of ≥1 doses was 89% (95% CI, 42.7-97.9) against serotype 1 and 86.0% (95% CI, 51.2-99.7) against serotype 19A. Serotype 3 showed a non-statistically significant effectiveness (25.9%; 95% CI, -65.3 to 66.8). The effectiveness of ≥1 doses of PCV13 in preventing IPD caused by all PCV13 serotypes in children aged 7-59 months was good and, except for serotype 3, the effectiveness of ≥1 doses against the most frequent PCV13 serotypes causing IPD was high when considered individually.

2016-01-01

Background The existing information on oral rehabilitations with dental implants in VIH-positive patients is scarce and of poor quality. Moreover, no long-term follow-up studies are available. Hence, the aims of this study were to describe the long-term survival and success rates of dental implants in a group of HIV-positive patients and to identify the most common postoperative complications, including peri-implant diseases. Material and Methods A retrospective case series of HIV-positive subjects treated with dental implants at the School of Dentistry of the University of Barcelona (Spain) was studied. Several clinical parameters were registered, including CD4 cell count, viral load and surgical complications. Additionally, the patients were assessed for implant survival and success rates and for the prevalence of peri-implant diseases. A descriptive statistical analysis of the data was performed. Results Nine participants (57 implants) were included. The patients’ median age was 42 years (IQR=13.5 years). The implant survival and success rates were 98.3% and 68.4%, respectively, with a mean follow-up of 77.5 months (SD=16.1 months). The patient-based prevalence of peri-implant mucositis and peri-implantitis were 22.2% and 44.4% respectively at the last appointment. Patients that attended regular periodontal maintenance visits had significantly less mean bone loss than non-compliant patients (1.3 mm and 3.9 mm respectively). Conclusions Oral rehabilitation with dental implants in HIV-positive patients seems to provide satisfactory results. In order to reduce the considerably high prevalence of peri-implant diseases, strict maintenance programmes must be implemented. Key words:HIV infection, dental implants, oral implantology, complications, peri-implantitis, peri-implant diseases. PMID:26946205

There is in the study selection bias, as it is performed in patients attending in a Primary Care Laboratory and not in a sample of the general population. Prevalence epidemiological data are therefore approximate and provisional. Copyright © 2013 Elsevier España, S.L. y SEA. All rights reserved.

Intratumoral heterogeneity and clonal evolution in blood malignancies and solid tumors.

PubMed

Varela, Ignacio; Menendez, Pablo; Sanjuan-Pla, Alejandra

2017-09-12

This meeting held at the University of Barcelona in March 2017, brought together scientists and clinicians worldwide to discuss current and future clinico-biological implications of intratumoral heterogeneity (ITH) and subclonal evolution in cancer diagnosis, patient stratification, and treatment resistance in diagnosis, treatment and follow-up. There was consensus that both longitudinal and tumor multi-region studies in matched samples are needed to better understand the dynamics of ITH. The contribution of the epigenome and microenvironment to ITH and subclone evolution remains understudied. It was recommended to combine computational, pathology and imaging tools to study the role of the microenvironment in subclone selection/evolution.

To describe the process of development of community health in a territory where the Primary Health Care board decided to include it in its roadmap as a strategic line. Evaluative research using qualitative techniques, including SWOT analysis on community health. Two-steps study. Primary care teams (PCT) of the Catalan Health Institute in Barcelona city. The 24 PCT belonging to the Muntanya-Dreta Primary Care Service in Barcelona city, with 904 professionals serving 557,430 inhabitants. Application of qualitative methodology using SWOT analysis in two steps (two-step study). Step 1: Setting up a core group consisting of local PCT professionals; collecting the community projects across the territory; SWOT analysis. Step 2: From the needs identified in the previous phase, a plan was developed, including a set of training activities in community health: basic, advanced, and a workshop to exchange experiences from the PCTs. A total of 80 team professionals received specific training in the 4 workshops held, one of them an advanced level. Two workshops were held to exchange experiences with 165 representatives from the local teams, and 22 PCTs presenting their practices. In 2013, 6 out of 24 PCTs have had a community diagnosis performed. Community health has achieved a good level of development in some areas, but this is not the general situation in the health care system. Its progression depends on the management support they have, the local community dynamics, and the scope of the Primary Health Care. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

To study the use of the Pregnancy occupational risk benefit (PORB) and non-work related sickness absence (NWSA) in a cohort of pregnant workers of Parc de Salut Mar, Barcelona (Spain). Retrospective cohort study of 428 pregnant workers between 2010 and 2014, who were followed-up until delivery. Absences from work, both PORB and NWSA were recorded until the beginning of their maternity leave. The sequence analysis identifies four trajectories, which are described according to workers demographic and job characteristics. Of the total cohort, 56 (13.1%) accessed only the PORB, representing 6.126 days of absence; 68 (15.9%) also accessed PORB, with 7.127 days of absence, but had previously accumulated 102 episodes of NWSA with 1.820 days of absence. The majority of pregnant workers in the sample (69.9%) took only one or several episodes of NWSA without using PORB, with 545 episodes and 26,337 days of absence. Most were active during the first quarter and it is from the second quarter that episodes of long-term NWSA appeared. During the last month of pregnancy more than 80% of the workers were absent from work. Pregnant workers remained at work for two thirds of their pregnancy. Absences were mainly due to episodes of NWSA. PORB represented one third of them. As in other similar countries, our results suggest a change in the management of social protection benefits for pregnant workers. Copyright © 2018 SESPAS. Publicado por Elsevier España, S.L.U.

The objective of this study was to evaluate the association between the presence of mandibular third molars and the occurrence of carious lesions in the distal aspect of the mandibular second molar. A retrospective cohort study comprising 327 lower third molars extracted in the Oral Surgery and Implantology Master's Degree program of the School of Dentistry of the University of Barcelona (Barcelona, Spain) was carried out. A descriptive and bivariate analysis was made. The diagnosis of caries in the second molar and the position of the mandibular third molar were evaluated through panoramic radiographies. The sample included 203 patients, 94 males (46.3%) and 109 females (53.7%), with a mean age of 26,8 years and 327 lower third molars. The prevalence of second molar distal caries was 25.4% (95% CI= 20.6% to 30.2%). This pathology was significantly more frequent when the third molar was in a horizontal position (27.7%), when the contact point was at (45,8%) or below (47.0%) the cementoenamel junction (CEJ), and when the distal CEJ of the mandibular second molar and the mesial CEJ of the third molar was 7 to 12 mm apart. Horizontal lower third molars with contact points at or below the CEJ are more likely to produce distal caries in the mandibular second molars. Due to the high prevalence of this pathology (20.6% to 30.2%), a prophylactic removal of lower third molars with the above-mentioned features might be advisable. Key words: Second molar, caries, third molar, prophylactic removal.

Background: The aim of present study is to determine the long-term results of patients who undergo pars plana vitrectomy after retained nucleus into the vitreous. Setting: Service of Ophthalmology, Hospital Universitari St Joan, Reus (Barcelona), Spain. Methods: Retrospective, noncomparative, consecutive case series. Medical records were reviewed of all patients who underwent pars plana vitrectomy for retained nucleus into the vitreous after complicated cataract surgery, over a 9-year period between August 1, 1997 and July 31, 2005. Result: The incidence of retained lens fragments was 0.57% (63 patients), the postoperative visual acuity was higher than 20/40 in 59.60% and fell to 48.93% by the end of the study, and was related to the presence of CME and retinal detachment. The CME appeared in 31.91% of the patients and was related to preoperative uveitis an corneal edema. In the group of patients on whom the vitrectomy was performed at the time of cataract complication, visual acuity was higher than 20/40 in 77.77%, and no one developed secondary glaucoma or uveitis. Conclusion: Being retrospective, our study was not result conclusive. Despite the initial good results of these patients after PPV surgery, follow-up should be accurate and over a long period of time in order to minimize postoperative complications such as retinal detachment, retinal breaks, secondary glaucoma and CME.

Accuracy in the estimation of quantitative minimal area from the diversity/area curve.

PubMed

Vives, Sergi; Salicrú, Miquel

2005-05-01

The problem of representativity is fundamental in ecological studies. A qualitative minimal area that gives a good representation of species pool [C.M. Bouderesque, Methodes d'etude qualitative et quantitative du benthos (en particulier du phytobenthos), Tethys 3(1) (1971) 79] can be discerned from a quantitative minimal area which reflects the structural complexity of community [F.X. Niell, Sobre la biologia de Ascophyllum nosodum (L.) Le Jolis en Galicia, Invest. Pesq. 43 (1979) 501]. This suggests that the populational diversity can be considered as the value of the horizontal asymptote corresponding to the curve sample diversity/biomass [F.X. Niell, Les applications de l'index de Shannon a l'etude de la vegetation interdidale, Soc. Phycol. Fr. Bull. 19 (1974) 238]. In this study we develop a expression to determine minimal areas and use it to obtain certain information about the community structure based on diversity/area curve graphs. This expression is based on the functional relationship between the expected value of the diversity and the sample size used to estimate it. In order to establish the quality of the estimation process, we obtained the confidence intervals as a particularization of the functional (h-phi)-entropies proposed in [M. Salicru, M.L. Menendez, D. Morales, L. Pardo, Asymptotic distribution of (h,phi)-entropies, Commun. Stat. (Theory Methods) 22 (7) (1993) 2015]. As an example used to demonstrate the possibilities of this method, and only for illustrative purposes, data about a study on the rocky intertidal seawed populations in the Ria of Vigo (N.W. Spain) are analyzed [F.X. Niell, Estudios sobre la estructura, dinamica y produccion del Fitobentos intermareal (Facies rocosa) de la Ria de Vigo. Ph.D. Mem.

2012-01-01

Background We have studied the possible effects of an intensive lifestyle change program on plasma fibrinogen levels, in patients with no cardiovascular disease, with elevated levels of fibrinogen, normal cholesterol levels, and a moderate estimated risk of coronary heart disease (CHD) and we have also analysed whether the effect on fibrinogen is independent of the effect on lipids. Results This clinical trial was controlled, unblinded and randomized, with parallel groups, done in 13 Basic Health Areas (BHA) in l'Hospitalet de Llobregat (Barcelona) and Barcelona city. The study included 436 patients, aged between 35 and 75 years, with no cardiovascular disease, elevated levels of fibrinogen (> 300 mg/dl), cholesterol < 250 mg/dl, 218 of whom received a more intensive intervention consisting of advice on lifestyle and treatment. The follow-up frequency of the intervention group was every 2 months. The other 218 patients followed their standard care in the BHAs. Fibrinogen, plasma cholesterol and other clinical biochemistry parameters were assessed. The evaluation of the baseline characteristics of the patients showed that both groups were homogenous. Obesity and hypertension were the most prevalent risk factors. After 24 months of the study, statistically significant changes were seen between the adjusted means of the two groups, for the following parameters: fibrinogen, plasma cholesterol, systolic and diastolic blood pressure and body mass index. Conclusion Intensive intervention to achieve lifestyle changes has shown to be effective in reducing some of the estimated CHD factors. However, the effect of intensive intervention on plasma fibrinogen levels did not correlate with the variations in cholesterol. Trial Registration ClinicalTrials.gov: NCT01089530 PMID:22381072

Breast cancer is a challenge for women's health-related quality of life (QoL), compromising their physical health and emotional well-being. QoL is equally distributed among different social groups. The aim of this study to analyze the impact of clinical characteristics and social determinants of health on the QoL of a cohort of women diagnosed and/or treated for breast cancer between 2003 and 2013 in one of the main hospitals in Barcelona's public health network. We performed a descriptive cross-sectional study in a cohort of 2235 women with various stages of breast cancer at different stages of their disease. Data were obtained using questionnaires QLQ-C30 and QLQ-BR23 from the European Organization for Research and Treatment of Cancer (EORTC), which include a set of functional and symptomatic scales. We conducted descriptive and bivariate analysis using the Chi-Square test and adjusted for relevant variables using logistic regression. The dependent variables were the functional scales of QoL and the independent variables were sociodemographic and clinical variables. We observed significant differences for most QoL functions. Women from the most disadvantaged class, those in social isolation, or those who had suffered relapses showed the poorest results for most of the function scales. In contrast, age had differential effects depending on the function studied. The QoL of women diagnosed with breast cancer is closely linked to both their social and economic status, and to their stage of disease progression. It is necessary to explore interventions that focus on the social determinants of health in order to mitigate their effects on breast cancer survivors' QoL. Copyright © 2018 The Authors.

2018-02-01

Moisture adsorption isotherms and storability of dried hazelnut inshells and kernels produced in Oregon were evaluated and compared among cultivars, including Barcelona, Yamhill, and Jefferson. Experimental moisture adsorption data fitted to Guggenheim-Anderson-de Boer (GAB) model, showing less hygroscopic properties in Yamhill than other cultivars of inshells and kernels due to lower content of carbohydrate and protein, but higher content of fat. The safe levels of moisture content (MC, dry basis) of dried inshells and kernels for reaching kernel water activity (a w ) ≤0.65 were estimated using the GAB model as 11.3% and 5.0% for Barcelona, 9.4% and 4.2% for Yamhill, and 10.7% and 4.9% for Jefferson, respectively. Storage conditions (2 °C at 85% to 95% relative humidity [RH], 10 °C at 65% to 75% RH, and 27 °C at 35% to 45% RH), times (0, 4, 8, or 12 mo), and packaging methods (atmosphere vs. vacuum) affected MC, a w , bioactive compounds, lipid oxidation, and enzyme activity of dried hazelnut inshells or kernels. For inshells packaged at woven polypropylene bag, MC and a w of inshells and kernels (inside shells) increased at 2 and 10 °C, but decreased at 27 °C during storage. For kernels, lipid oxidation and polyphenol oxidase activity also increased with extended storage time (P < 0.05), and MC and a w of vacuum packaged samples were more stable during storage than those atmospherically packaged ones. Principal component analysis showed correlation of kernel qualities with storage condition, time, and packaging method. This study demonstrated that the ideal storage condition or packaging method varied among cultivars due to their different moisture adsorption and physicochemical and enzymatic stability during storage. Moisture adsorption isotherm of hazelnut inshells and kernels is useful for predicting the storability of nuts. This study found that water adsorption and storability varied among the different cultivars of nuts, in which Yamhill was less hygroscopic than Barcelona and Jefferson, thus more stable during storage. For ensuring food safety and quality of nuts during storage, each cultivar of kernels should be dried to a certain level of MC. Lipid oxidation and enzyme activity of kernel could be increased with extended storage time. Vacuum packaging was recommended to kernels for reducing moisture adsorption during storage. © 2018 Institute of Food Technologists®.

The objective of this study was to compare cases of imported malaria originating from the Spanish ex-colony of Equatorial Guinea (EG) with those originating from the rest of Africa (RA). All the African cases detected in Barcelona between 1989 and 2007 were investigated in a retrospective analysis. Clinical-epidemiological variables such as sex, age, visiting friends and relatives (VFR), species, hospital admission and chemo-prophylaxis were compared. Data were analysed by logistic regression, calculating the Odds Ratio (OR) and 95% Confidence Intervals (95% CI). Of the 489 African patients, 279 (57,1%) had been born in EG and 210 (42,9%) in the rest of Africa. The cumulative incidence of imported malaria among those from EG was 179.6 per thousand inhabitants, while in those from the RA it was 33.7 per thousand (p < 0.001). Compliance with chemoprophylaxis (CP) was very low, but there were no differences between the two groups. Comparing those from EG to those from RA, the former were characterized by having more patients in the visiting friends and relatives (VFR) category, and more individuals younger than 15 years or older than 37 years, and more women. They also visited a traveller's health centre more often, had fewer hospital admissions and were less likely to reside in the inner city. Cases of imported malaria originating in Africa, are more likely to come from the Spanish ex-colony of EG, and VFR are more likely to be affected. It is recommended that developed countries promote prevention programmes, such as CP advice directed at African immigrants, and develop programmes of cooperation against malaria in their ex-colonies.

2015-01-01

The objective of the study was to analyze the descriptive epidemiology and costs of herpes zoster (HZ) and postherpetic neuralgia (PHN) in people aged ≥50 years in Catalonia (Spain). The incidence of HZ in Catalonia was estimated by extrapolating the incidence data from Navarre (Spain) to the population of Catalonia. The incidence of PHN was estimated according to the proportion of cases of HZ in the case series of the Hospital del Sagrado Corazón de Barcelona that evolved to PHN. Drug costs were obtained directly from the prescriptions included in the medical record (according to official prices published by the General Council of the College of Pharmacists). The cost of care was obtained by applying the tariffs of the Catalan Health Institute to the number of outpatient visits and the number and duration of hospital admissions. The estimated annual incidence of HZ was 31 763, of which 21 532 (67.79%) were in patients aged ≥50 years. The respective figures for PHN were 3194 and 3085 (96.59) per annum, respectively. The mean cost per patient was markedly higher in cases of PHN (916.66 euros per patient) than in cases of HZ alone (301.52 euros per patient). The cost increased with age in both groups of patients. The estimated total annual cost of HZ and its complications in Catalonia was € 9.31 million, of which 6.54 corresponded to HZ and 2.77 to PHN. This is the first Spanish study of the disease burden of HZ in which epidemiological data and costs were collected directly from medical records. The estimated incidence of HZ is probably similar to the real incidence. In contrast, the incidence of PHN may be an underestimate, as around 25% of patients in Catalonia attend private clinics financed by insurance companies. It is also probable that the costs may be an underestimate as the costs derived from the prodromal phase were not included. In Catalonia, HZ and PHN cause an important disease burden (21 532 cases of HZ and 3085 de PHN with an annual cost of € 9.31 million) in people aged ≥50 years, in whom vaccination is indicated.

Here we report the discovery of a new late Lower Pleistocene site named Vallparadís (Barcelona, Spain) that produced a rich archeological and paleontological sequence dated from the upper boundary of the Jaramillo subchron to the early Middle Pleistocene. This deposit contained a main archeological layer with numerous artifacts and a rich macromammalian assemblage, some of which bore cut marks, that could indicate that hominins had access to carcasses. Paleomagnetic analysis, electron spin resonance-uranium series (ESR-US), and the biostratigraphic chronological position of the macro- and micromammal and lithic assemblages of this layer reinforce the proposal that hominins inhabited Europe during the Lower Pleistocene. The archeological sequence provides key information on the successful adaptation of European hominins that preceded the well-known fossil population from Atapuerca and succeeded the finds from Orce basin. Hence, this discovery enables us to close a major chronological gap in the early prehistory of Iberia. According to the information in this paper and the available data from these other sites, we propose that Mediterranean Western Europe was repeatedly and perhaps continuously occupied during the late Matuyama chron.

The beginning of Francoist psychiatry: the National Neurology and Psychiatry Conference (Barcelona, 1942).

PubMed

Huertas, Rafael

While there has been some research into Francoist psychiatry, much work still needs to be done on the reorganization of the mental health profession within the new state. Held in Barcelona on 12, 13 and 14th January 1942, the National Neurology and Psychiatry Conference undoubtedly played a major role in the attempt to overthrow the dominant ideas in the field of Spanish psychiatry and displace its most influential figures. This article seeks to analyse the Conference's main organizational features and examine its most significant content, with the aim of evaluating its strategic importance in the context of both the psychiatrists' professional and scientific interests and their ideological and political concerns. Conference papers tackled issues such as neurology and psychiatry in wartime, vitamin deficiency and the nervous system, and new psychiatric treatments, including shock therapy. The Conference's marked ideological nature represented the beginning of a new professional dynamic, featuring the emergence or establishment of new leaders intent on laying the foundations of psychiatry during the early years of the Franco regime.

European project RETAIN: new approach for IBC in teleradiology and PACS based on full ATM network

1995-05-01

This paper describes the RETAIN project (radiological examination transfer on ATM Integrated Network), which is supported by the European Community, in the frame of the TEN-IBC program (trans-European networks integrated broad band communication). It links together three European sites in France (Rennes), Spain (Barcelona), and Germany (Oldenburg) and involves a partnership between the public national operators France Telecom, Telefonica, and Telekom. One important reason to explicitly consider asynchronous transfer mode (ATM) for medical imaging is that multimedia applications on such networks allow integration of digital data and person-to-person communication. The RETAIN project includes trials of teleworking sessions between radiologists of Rennes and Barcelona within a clinical and/or scientific context based on ATM equipments performing DICOM transfer on examination, digital remote manipulation within a comprehensive dialogue, and high quality visiophony on ATM adaptation layer (AAL) type 1. The project includes also visiophony trials with Oldenburg and preparation of harmonized regional experimentation within an emergency context. The network used is a full 10 Mbits/s ATM network directly connected to local PACSs.

The neighborhood of Vallcarca, Barcelona - Spain, is located near the valley formed by the three hills called El Putxet, Creueta del Coll and Muntanya Pelada adjacent to the back area of Park Guell. Vallcarca first urbanized at the XIX century as a place to spend summer for the nearby inhabitants of the city of Barcelona. Since the end of XX century, the area has been under the pressure of different urban plannings and economic speculations that have just erase a big portion of its original physiognomy, without being able to organize a new area of town. The empty land that located at the former center and across Vallcarca becoming part of research to produce an outcome for compatible housing within the area. The data gives a focus on the social and urban rehabilitation of the neighborhood that introducing a program of social housing with communal facilities using an approach of connection and topography that existed on the site as a catalyst to change this fragmented part of the city into inclusive neighborhood.

This paper deals with the global control of the Riera Blanca catchment in the Barcelona sewer network using a predictive optimal control approach. This catchment has been modelled using a conceptual modelling approach based on decomposing the catchments in subcatchments and representing them as virtual tanks. This conceptual modelling approach allows real-time model calibration and control of the sewer network. The global control problem of the Riera Blanca catchment is solved using a optimal/predictive control algorithm. To implement the predictive optimal control of the Riera Blanca catchment, a software tool named CORAL is used. The on-line control is simulated by interfacing CORAL with a high fidelity simulator of sewer networks (MOUSE). CORAL interchanges readings from the limnimeters and gate commands with MOUSE as if it was connected with the real SCADA system. Finally, the global control results obtained using the predictive optimal control are presented and compared against the results obtained using current local control system. The results obtained using the global control are very satisfactory compared to those obtained using the local control.

The present work assesses indoor air quality in stations of the Barcelona subway system. PM2.5 concentrations on the platforms of 4 subway stations were measured during two different seasons and the chemical composition was determined. A Positive Matrix Factorization analysis was performed to identify and quantify the contributions of major PM2.5 sources in the subway stations. Mean PM2.5 concentrations varied according to the stations design and seasonal periods. PM2.5 was composed of haematite, carbonaceous aerosol, crustal matter, secondary inorganic compounds, trace elements, insoluble sulphate and halite. Organic compounds such as PAHs, nicotine, levoglucosan and aromatic musk compounds were also identified. Subway PM2.5 source comprised emissions from rails, wheels, catenaries, brake pads and pantographs. The subway source showed different chemical profiles for each station, but was always dominated by Fe. Control actions on the source are important for the achievement of better air quality in the subway environment. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

Rheumatoid arthritis (RA), an important cause of disability, affects 1% of the population. Early diagnosis and referral to a rheumatologist are positive prognostic factor but diagnosis in many cases is in the hands of primary care physicians (PCP). To determine the criteria used by PCP for diagnosis of RA and referral of these patients to a rheumatologist; to evaluate how many cases can be classified as RA according to the ACR. Retrospective study of 530 patients referred by PCP and seen as outpatients at a rheumatology clinic in 2002. Patients with referral diagnosis of RA were identified and symptoms, signs, functional capacity and ACR criteria for RA were evaluated by 2 rheumatologists. 302 patients had a referral diagnosis of RA, 33 male (10.9%) and 269 female (89.1%), median age 50.5 years, with a median time since diagnosis of 45.2 months. 57.9% had FC stage II. 100% of cases had "generalized" joint pain, 67.5% arthritis of 3 or more joints and 51.7% arthritis of hand joints. Arthritis was symmetrical in 58.9% and 77.2% of the patients had morning stiffness (> 30 min). 49.7% of the cases had positive rheumatoid factor, 19.2% had a negative RF and 31.1% had none reported. In 2% ESR was measured. X-ray erosions were reported in 6.6% of cases. When using the ACR criteria, 17.8% of patients had 1, 28.7% had 2 and 53.5% had 3 or more criteria. In only 59 cases (20%) did the rheumatologist agree with the referral diagnosis of RA. 80% of PCP referrals of RA to the rheumatologist were another disease. A poor clinical evaluation and little support from laboratory and x-rays was noticed. The delay in diagnosis and referral was 3 years, worsening prognosis. A vigorous effort in educating PCP is needed to achieve early diagnosis and referral of RA cases. Copyright © 2006 Elsevier España S.L. Barcelona. Published by Elsevier Espana. All rights reserved.

To estimate the effect of opening two services for people who use drugs and three police interventions on the number of discarded syringes collected from public spaces in Barcelona between 2004 and 2014. We conducted an interrupted time-series analysis of the monthly number of syringes collected from public spaces during this period. The dependent variable was the number of syringes collected per month. The main independent variables were month and five dummy variables (the opening of two facilities with safe consumption rooms, and three police interventions). To examine which interventions affected the number of syringes collected, we performed an interrupted time-series analysis using a quasi-Poisson regression model, obtaining relative risks (RR) and 95% confidence intervals (CIs). The number of syringes collected per month in Barcelona decreased from 13,800 in 2004 to 1655 in 2014 after several interventions. For example, following the closure of an open drug scene in District A of the city, we observed a decreasing trend in the number of syringes collected [RR=0.88 (95% CI: 0.82-0.95)], but an increasing trend in the remaining districts [RR=1.11 (95% CI: 1.05-1.17) and 1.08 (95% CI: 0.99-1.18) for districts B and C, respectively]. Following the opening of a harm reduction facility in District C, we observed an initial increase in the number collected in this district [RR=2.72 (95% CI: 1.57-4.71)] and stabilization of the trend thereafter [RR=0.97 (95% CI: 0.91-1.03)]. The overall number of discarded syringes collected from public spaces has decreased consistently in parallel with a combination of police interventions and the opening of harm reduction facilities.

During the SAPUSS campaign (Solving Aerosol Problems by Using Synergistic Strategies) PM10 samples at 12-hour resolution were simultaneously collected at four monitoring sites located in the urban agglomerate of Barcelona (Spain). A total of 221 samples were collected from 20 September to 20 October 2010. The Road Site (RS) site and the Urban Background (UB) site were located at street level, whereas the Torre Mapfre (TM) and the Torre Collserola (TC) sites were located at 150 m a.s.l. by the sea side within the urban area and at 415 m a.s.l. 8 km inland, respectively. For the first time, we are able to report simultaneous PM10 aerosol measurements, allowing us to study aerosol gradients at both horizontal and vertical levels. The complete chemical composition of PM10 was determined on the 221 samples, and factor analysis (positive matrix factorisation, PMF) was applied. This resulted in eight factors which were attributed to eight main aerosol sources affecting PM10 concentrations in the studied urban environment: (1) vehicle exhaust and wear (2-9 µg m-3, 10-27 % of PM10 mass on average), (2) road dust (2-4 µg m-3, 8-12 %), (3) mineral dust (5 µg m-3, 13-26 %), (4) aged marine (3-5 µg m-3, 13-20 %), (5) heavy oil (0.4-0.6 µg m-3, 2 %), (6) industrial (1 µg m-3, 3-5 %), (7) sulfate (3-4 µg m-3, 11-17 %) and (8) nitrate (4-6 µg m-3, 17-21 %). Three aerosol sources were found to be enhanced at the ground levels (confined within the urban ground levels of the city) relative to the upper levels: (1) vehicle exhaust and wear (2.8 higher), (2) road dust (1.8 higher) and (3) local urban industries/crafts workshops (1.6 higher). Surprisingly, the other aerosol sources were relatively homogeneous at both horizontal and vertical levels. However, air mass origin and meteorological parameters also played a key role in influencing the variability of the factor concentrations. The mineral dust and aged marine factors were found to be a mixture of natural and anthropogenic components and were thus further investigated. Overall, three types of dust were identified to affect the urban study area: road dust (35 % of the mineral dust load, 2-4 µg m-3 on average), Saharan dust (28 %, 2.1 µg m-3) and background mineral dust (37 %, 2.8 µg m-3). Our results evidence that although the city of Barcelona broadly shows a homogeneous distribution of PM10 pollution sources, non-exhaust traffic, exhaust traffic and local urban industrial activities are major coarse PM10 aerosol sources.

Long-term strategies of climate change adaptation to manage flooding events in urban areas

NASA Astrophysics Data System (ADS)

Pouget, Laurent; Russo, Beniamino; Redaño, Angel; Ribalaygua, Jaime

2010-05-01

Heavy and sudden rainfalls regularly affect the Mediterranean area, so a great number of people and buildings are exposed to the risk of rain-generated floods. Climate change is expected to modify this risk and, in the case that extreme rainfalls increase in frequencies and intensity, this could result in important damages, particularly in urban areas. This paper presents a project that aims to determine adaptation strategies to future flood risks in urban areas. It has been developed by a panel of water companies (R+i Alliance funding), and includes the evaluation of the climate change impact on the extreme rainfall, the use of innovative modelling tools to accurately forecast the flood risk and, finally, the definition of a pro-active and long-term planning against floods. This methodology has been applied in the city of Barcelona. Current climate models give some projections that are not directly applicable for flood risk studies, either because they do not have an adequate spatial and temporal resolution, or because they do not consider some important local factors, such as orography. These points have been considered within the project, when developing the design storms corresponding to future climatic conditions (e.g. years 2030 or 2050). The methodology uses statistical downscaling techniques based on global climate models predictions, including corrections for extreme events and convective storms, as well as temporal downscaling based on historical observations. The design storms created are used in combination with the predictions of sea level rise and land use evolutions to determine the future risk of flooding in the area of study. Once the boundary conditions are known, an accurate flood hazard assessment is done. It requires a local knowledge of the flow parameters in the whole analyzed domain. In urban catchments, in order to fulfill this requirement, powerful hydrological and hydraulic tools and detailed topographic data represent the unique way for a local estimation of the flow parameters (flow depth, flow velocity, flood duration, etc.). If urban floods are caused by heavy rainfall events and a quick hydrological response of the catchment, the approach to elaborate a flood hazard assessment study should take into account the drainage system capacity, too (in terms of effectiveness of surface drainage structures, as well as storm sewerages). In these cases, the hydrological modelling of the involved subcatchments should be linked to the runoff propagation 2D modelling on the urban surface and the hydraulics of the storm sewers (dual drainage modelling) through a coupled 2D/1D approach. The design storm created and the 2D/1D modelling approach have been used to simulate the future flood risk in the city of Barcelona. From the simulation results, it is possible to understand the flooding processes and the risk associated. It is therefore possible to develop some long-term adaptation strategies to reduce the flood risk for current and future climatic conditions, such as structural measures (e.g. improvement of the stormwater network) and non-structural measures (e.g. enhancement of the flood warning system).

The mortality of patients with bacteremic osteoarticular infections (B-OAIs) is poorly understood. Whether certain types of OAIs carry higher mortality or interventions like surgical debridement can improve prognosis, are unclarified questions. Retrospective analysis of a prospective cohort of patients with B-OAIs treated at a teaching hospital in Barcelona (1985-2014), analyzing mortality (30-day case-fatality rate). B-OAIs were categorized as peripheral septic arthritis or other OAIs. Factors influencing mortality were analyzed using logistic regression models. The association of surgical debridement with mortality in patients with peripheral septic arthritis was evaluated with a multivariate logistic regression model and a propensity score matching analysis. Among 650 cases of B-OAIs, mortality was 12.2% (41.8% of deaths within 7 days). Compared with other B-OAI, cases of peripheral septic arthritis were associated with higher mortality (18.6% vs 8.3%, p < 0.001). In a multiple logistic regression model, peripheral septic arthritis was an independent predictor of mortality (adjusted odds ratio [OR] 2.12; 95% CI: 1.22-3.69; p = 0.008). Cases with peripheral septic arthritis managed with surgical debridement had lower mortality than those managed without surgery (14.7% vs 33.3%; p = 0.003). Surgical debridement was associated with reduced mortality after adjusting for covariates (adjusted OR 0.23; 95% CI: 0.09-0.57; p = 0.002) and in the propensity score matching analysis (OR 0.81; 95% CI: 0.68-0.96; p = 0.014). Among patients with B-OAIs, mortality was greater in those with peripheral septic arthritis. Surgical debridement was associated with decreased mortality in cases of peripheral septic arthritis.

The area of mobile technologies applied to health (mHealth) is a growing worldwide trend that has generated enormous expectations for the mitigation of problems related to medical services delivery and public health stemming from a lack of resources and the limited number of specialists. The numerous opportunities offered by mobile technologies, together with their ease of use, have attracted the interest both of governments and universities. This is the case of the Ibero-American Mobile Technologies and Health Network (CYTED-RITMOS, Spanish acronym). As a result of the network's first year of activity, in October 2015 the RITMOS International Workshop was held in Barcelona to present the priority areas in Latin America where research, development, and innovation (R&D+i) projects on mobile health could be carried out and possible solutions found. The objective of this article is to present the potentialities and applicability of mHealth in the Region of the Americas.

Attitudes of students of a health sciences university towards the extension of smoke-free policies at the university campuses of Barcelona (Spain).

Martínez, Cristina; Méndez, Carlos; Sánchez, María; Martínez-Sánchez, José María

To assess attitudes towards the extension of outdoor smoke-free areas on university campuses. Cross-sectional study (n=384) conducted using a questionnaire administered to medical and nursing students in Barcelona in 2014. Information was obtained pertaining to support for indoor and outdoor smoking bans on university campuses, and the importance of acting as role models. Logistic regression analyses were performed to examine agreement. Most of the students agreed on the importance of health professionals and students as role models (74.9% and 64.1%, respectively) although there were statistically significant differences by smoking status and age. 90% of students reported exposure to smoke on campus. Students expressed strong support for indoor smoke-free policies (97.9%). However, only 39.3% of participants supported regulation of outdoor smoking for university campuses. Non-smokers (OR=12.315; 95% CI: 5.377-28.204) and students ≥22 years old (OR=3.001; 95% CI: 1.439-6.257) were the strongest supporters. The students supported indoor smoke-free policies for universities. However, support for extending smoke-free regulations to outdoor areas of university campuses was limited. It is necessary to educate students about tobacco control and emphasise their importance as role models before extending outdoor smoke-free legislation at university campuses.

To demonstrate the impact of the incorporation of quality indicators in assessing the technical efficiency of primary healthcare teams. The processes through which primary healthcare resources have been allocated since the onset of the financial crisis in 2008 have focussed on quantitative rather than qualitative indicators. This study applies data envelopment analysis (DEA) techniques to 58 primary healthcare teams from three different primary healthcare services from the province of Barcelona (Spain). We combine publicly available information from the regional government of Catalonia with data requested from the Catalan Health System Observatory. The analysis compares the results of three models, thereby allowing shifts in the efficiency of primary healthcare teams to be identified in terms of the (lack of) consideration for healthcare quality indicators. Only 16% of the primary healthcare teams were found to be efficient according to the baseline models, which only incorporated input and output quantity indicators. However, once proxies for healthcare quality are included in the analysis, this percentage increases to 58.6%. No meaningful differences in primary healthcare team efficiency were found between public and privately owned centres, between regional primary care services and organisational models, or between rural and urban teams. The results suggest the need to incorporate healthcare quality indicators as outputs when considering criteria for the streamlining of primary healthcare services. Failure to incorporate quality indicators is associated with various primary healthcare concepts. Copyright © 2016 SESPAS. Publicado por Elsevier España, S.L.U. All rights reserved.

The relationship between weather conditions and psychiatric disorders has been a continuous subject of speculation due to contradictory findings. This study attempts to further clarify this relationship by focussing on specific conditions such as panic attacks and non-panic anxiety in relation to specific meteorological variables. All psychiatric emergencies attended at a general hospital in Barcelona (Spain) during 2002 with anxiety as main complaint were classified as panic or non-panic anxiety according to strict independent and retrospective criteria. Both groups were assessed and compared with meteorological data (wind speed and direction, daily rainfall, temperature, humidity and solar radiation). Seasons and weekend days were also included as independent variables. Non-parametric statistics were used throughout since most variables do not follow a normal distribution. Logistic regression models were applied to predict days with and without the clinical condition. Episodes of panic were three times more common with the poniente wind (hot wind), twice less often with rainfall, and one and a half times more common in autumn than in other seasons. These three trends (hot wind, rainfall and autumn) were accumulative for panic episodes in a logistic regression formula. Significant reduction of episodes on weekends was found only for non-panic episodes. Panic attacks, unlike other anxiety episodes, in a psychiatric emergency department in Barcelona seem to show significant meteorotropism. Assessing specific disorders instead of overall emergencies or other variables of a more general quality could shed new light on the relationship between weather conditions and behaviour.

Children spend a third of their day in the classroom, where air pollution levels may differ substantially from those outdoors due to specific indoor sources. Air pollution exposure assessments based on atmospheric particle mass measured outdoors may therefore have little to do with the daily PM dose received by school children. This study aims to investigate outdoor and indoor sources of PM2.5 measured at 39 primary schools in Barcelona during 2012. On average 47% of indoor PM2.5 measured concentrations was found to be generated indoors due to continuous resuspension of soil particles (13%) and a mixed source (34%) comprising organic (skin flakes, clothes fibers, possible condensation of VOCs) and Ca-rich particles (from chalk and building deterioration). Emissions from seven outdoor sources penetrated easily indoors being responsible for the remaining 53% of measured PM2.5 indoors. Unpaved playgrounds were found to increase mineral contributions in classrooms by 5-6 μg/m(3) on average with respect to schools with paved playgrounds. Weekday traffic contributions varied considerably across Barcelona within ranges of 1-14 μg/m(3) outdoor and 1-10 μg/m(3) indoor. Indoors, traffic contributions were significantly higher (more than twofold) for classrooms with windows oriented directly to the street, rather than to the interior of the block or to playgrounds. This highlights the importance of urban planning in order to reduce children's exposure to traffic emissions. Copyright © 2014 Elsevier B.V. All rights reserved.

Rooftop greenhouses in educational centers: A sustainability assessment of urban agriculture in compact cities.

2018-06-01

Today, urban agriculture is one of the most widely used sustainability strategies to improve the metabolism of a city. Schools can play an important role in the implementation of sustainability master plans, due their socio-educational activities and their cohesive links with families; all key elements in the development of urban agriculture. Thus, the main objective of this research is to develop a procedure, in compact cities, to assess the potential installation of rooftop greenhouses (RTGs) in schools. The generation of a dynamic assessment tool capable of identifying and prioritizing schools with a high potential for RTGs and their eventual implementation would also represent a significant factor in the environmental, social, and nutritional education of younger generations. The methodology has four-stages (Pre-selection criteria; Selection of necessities; Sustainability analysis; and Sensitivity analysis and selection of the best alternative) in which economic, environmental, social and governance aspects all are considered. It makes use of Multi-Attribute Utility Theory and Multi-Criteria Decision Making, through the Integrated Value Model for Sustainability Assessments and the participation of two panels of multidisciplinary specialists, for the preparation of a unified sustainability index that guarantees the objectivity of the selection process. This methodology has been applied and validated in a case study of 11 schools in Barcelona (Spain). The social perspective of the proposed methodology favored the school in the case-study with the most staff and the largest parent-teacher association (social and governance indicators) that obtained the highest sustainability index (S11); at a considerable distance (45%) from the worst case (S3) with fewer school staff and parental support. Finally, objective decisions may be taken with the assistance of this appropriate, adaptable, and reliable Multi-Criteria Decision-Making tool on the vertical integration and implementation of urban agriculture in schools, in support of the goals of sustainable development and the circular economy.

Roche, Enric; Gómez-Durán, Esperanza L; Benet-Travé, Josep; Martin-Fumadó, Carles; Arimany-Manso, Josep

2014-02-01

Patient safety is a major concern worldwide, but particularly high rates of adverse events are reported in the surgery setting. Angiology and vascular surgery is of special interest due to the complexity of the pathologies involved and the esthetic component of some of its procedures. In this study we identified the most frequent factors that apply to vascular surgery claims to determine areas of special risk in vascular surgery, with an aim to improve patient safety. We performed a retrospective and descriptive study of the claims pertaining to vascular surgery from the database of the Service of Professional Liability (SRP) of the Official College of Physicians of Barcelona. The time frame of data collection was from 1986 to 2009. We analyzed both the clinical and legal characteristics of the cases. Of the total of 6952 registered claims during the 23-year period, 91 (1.3%) were related to the practice of vascular surgery. Of these, 53.8% were related to venous pathology and 46.1% to arterial pathology. Neurologic damage was the main motive for claims (15.3%), followed by thromboembolic disease (14.2%), burns as a result of cosmetic treatment (12%), and amputation (10.9%). The neurologic damage in relation to vein pathology registered the greatest proportion of cases with professional liability (30.8%), followed by burns (19.2%), forgotten gauze (11.5%), and amputations (11.5%). Angiology and vascular surgery does not seem to be a specialty with a high risk for claims, but complications, such as thromboembolic disease and neurologic damage after varicose vein intervention, do occur and deserve special attention so improvements can be made to patient safety.

Economic evaluation of three populational screening strategies for cervical cancer in the county of Valles Occidental: CRICERVA clinical trial

PubMed Central

2011-01-01

Background A high percentage of cervical cancer cases have not undergone cytological tests within 10 years prior to diagnosis. Different population interventions could improve coverage in the public system, although costs will also increase. The aim of this study was to compare the effectiveness and the costs of three types of population interventions to increase the number of female participants in the screening programmes for cancer of the cervix carried out by Primary Care in four basic health care areas. Methods/Design A cost-effectiveness analysis will be performed from the perspective of public health system including women from 30 to 70 years of age (n = 20,994) with incorrect screening criteria from four basic health care areas in the Valles Occidental, Barcelona, Spain. The patients will be randomly distributed into the control group and the three intervention groups (IG1: invitation letter to participate in the screening; IG2: invitation letter and informative leaflet; IG3: invitation letter, informative leaflet and a phone call reminder) and followed for three years. Clinical effectiveness will be measured by the number of HPV, epithelial lesions and cancer of cervix cases detected. The number of deaths avoided will be secondary measures of effectiveness. The temporal horizon of the analysis will be the life expectancy of the female population in the study. Costs and effectiveness will be discounted at 3%. In addition, univariate and multivariate sensitivity analysis will be carried out. Discussion IG3 is expected to be more cost-effective intervention than IG1 and IG2, with greater detection of HPV infections, epithelial lesions and cancer than other strategies, albeit at a greater cost.

Incidence of Hepatitis C Infection among Prisoners by Routine Laboratory Values during a 20-Year Period

PubMed Central

Marco, Andrés; Gallego, Carlos; Caylà, Joan A.

2014-01-01

Background To estimate the incidence of Hepatitis C virus (HCV) and the predictive factors through repeated routine laboratory analyses. Methods An observational cohort study was carried out in Quatre Camins Prison, Barcelona. The study included subjects with an initial negative HCV result and routine laboratory analyses containing HCV serology from 1992 to 2011. The incidence of infection was calculated for the study population and for sub-groups by 100 person-years of follow-up (100 py). The predictive factors were determined through Kaplan-Meier curves and a Cox regression. Hazard ratios (HR) and 95% confidence intervals (CI) were calculated. Results A total of 2,377 prisoners were included with a median follow-up time of 1,540.9 days per patient. Among the total population, 117 HCV seroconversions were detected (incidence of 1.17/100 py). The incidence was higher between 1992 and 1995 (2.57/100 py), among cases with HIV co-infection (8.34/100 py) and among intravenous drug users (IDU) without methadone treatment (MT) during follow-up (6.66/100 py). The incidence rate of HCV seroconversion among cases with a history of IDU and current MT was 1.35/100 py, which is close to that of the total study population. The following variables had a positive predictive value for HCV infection: IDU (p<0.001; HR = 7,30; CI: 4.83–11.04), Spanish ethnicity (p = 0.009; HR = 2,03; CI: 1.93–3.44) and HIV infection (p = 0.015; HR = 1.97; CI: 1.14–3.39). Conclusion The incidence of HCV infection among prisoners was higher during the first part of the study and among IDU during the entire study period. Preventative programs should be directed toward this sub-group of the prison population. PMID:24587394

2016-09-20

This study reports spatial and temporal variability of Zn and Cu isotopes in atmospheric particulate matter (PM) collected in two major European cities with contrasting atmospheric pollution, Barcelona and London. We demonstrate that nontraditional stable isotopes identify source contributions of Zn and Cu and can play a major role in future air quality studies. In Barcelona, samples of fine PM were collected at street level at sites with variable traffic density. The isotopic signatures ranged between -0.13 ± 0.09 and -0.51 ± 0.05‰ for δ(66)ZnIRMM and between +0.04 ± 0.20 and +0.33 ± 0.15‰ for δ(65)CuAE633. Copper isotope signatures similar to those of Cu sulfides and Cu/Sb ratios within the range typically found in brake wear suggest that nonexhaust emissions from vehicles are dominant. Negative Zn isotopic signatures characteristic for gaseous emissions from smelting and combustion and large enrichments of Zn and Cd suggest contribution from metallurgical industries. In London, samples of coarse PM collected on the top of a building over 18 months display isotope signatures ranging between +0.03 ± 0.04 and +0.49 ± 0.02‰ for δ(66)ZnIRMM and between +0.37 ± 0.17 and +0.97 ± 0.21‰ for δ(65)CuAE633. Heavy Cu isotope signatures (up to +0.97 ± 0.21‰) and higher enrichments and Cu/Sb ratios during winter time indicate important contribution from fossil fuel combustion. The positive δ(66)ZnIRMM signatures are in good agreement with signatures characteristic for ore concentrates used for the production of tires and galvanized materials, suggesting nonexhaust emissions from vehicles as the main source of Zn pollution.

Background The objective of this study was to evaluate the association between the presence of mandibular third molars and the occurrence of carious lesions in the distal aspect of the mandibular second molar. Material and Methods A retrospective cohort study comprising 327 lower third molars extracted in the Oral Surgery and Implantology Master’s Degree program of the School of Dentistry of the University of Barcelona (Barcelona, Spain) was carried out. A descriptive and bivariate analysis was made. The diagnosis of caries in the second molar and the position of the mandibular third molar were evaluated through panoramic radiographies. Results The sample included 203 patients, 94 males (46.3%) and 109 females (53.7%), with a mean age of 26,8 years and 327 lower third molars. The prevalence of second molar distal caries was 25.4% (95% CI= 20.6% to 30.2%). This pathology was significantly more frequent when the third molar was in a horizontal position (27.7%), when the contact point was at (45,8%) or below (47.0%) the cementoenamel junction (CEJ), and when the distal CEJ of the mandibular second molar and the mesial CEJ of the third molar was 7 to 12 mm apart. Conclusions Horizontal lower third molars with contact points at or below the CEJ are more likely to produce distal caries in the mandibular second molars. Due to the high prevalence of this pathology (20.6% to 30.2%), a prophylactic removal of lower third molars with the above-mentioned features might be advisable. Key words:Second molar, caries, third molar, prophylactic removal. PMID:28638558

Abstract Background: Heart failure (HF) diagnosis as reported in primary care medical records is not always properly confirmed and could result in over-registration. Objectives: To determine the proportion of registered HF that can be confirmed with information from primary care medical records and to analyse related factors. Methods: A cross-sectional study. The medical records of 595 HF patients attended in two primary healthcare centres in Barcelona (Spain) were revised and validated by a team of experts who classified diagnosis into confirmed, unconfirmed, and misdiagnosis. Variables potentially related to the confirmation of the diagnosis were analysed. The revision of medical records and data collection took place from 15 January to 31 March 2014. Results: Mean (standard deviation) age was 78 (10) years and 58% were women. The diagnosis could be confirmed in 53.6% of patients. Factors associated with a greater probability of having a confirmed diagnosis were age (yearly OR: 0.97, 95%CI: 0.95–0.99), cardiologist follow-up (OR: 3.66, 95%CI: 2.46–5.48), history of ischaemic heart disease (OR: 2.18, 95%CI: 1.36–2.48), atrial fibrillation (OR: 2.01, 95%CI: 1.34–3.03), and prescription of loop diuretics (OR: 3.24, 95%CI: 2.14–4.89). Conclusion: Only in half of the patients labelled as HF in primary care medical records could this diagnosis be further confirmed. Variables regularly registered in clinical practice could help general practitioners identify those patients requiring a revision of their HF diagnosis. PMID:28376668

In Spain, two smoke-free laws have been passed (Law 28/2005 and Law 42/2010).This study evaluates the association between Spanish smoking legislations and the second-hand smoke (SHS) exposure in an adult non-smoking population cohort in Barcelona (Spain). This is a longitudinal study, before and after the implementation of two national smoking bans, in a representative sample of adults (≥16years old) from Barcelona (Spain) surveyed in 2004-2005 and followed up in 2013-2014 (n=736). We only analyzed non-smokers (n=397). We obtained 9ml of saliva sample for analysis of cotinine, a biomarker of recent tobacco exposure. We calculated geometric means of salivary cotinine concentration and their geometric standard deviation. We used linear mixed effect models, with individuals as random effects, to model the percentage change in salivary cotinine concentration and their 95% confidence intervals. The percentage of participants with saliva samples with measurable concentrations of cotinine fell from 92.4% to 64.2% after both Spanish smoking legislations. The geometric mean of salivary cotinine concentration significantly decreased 88% (from 0.98ng/mL to 0.12ng/mL, p<0.001) after the implementation of the two Spanish smoke-free legislations. The decrease of the GM salivary cotinine concentration was statistically significant independently of the sociodemographic variables. There was a large reduction in the salivary cotinine concentration among adult non-smokers and higher cotinine concentrations among those declaring exposure to SHS at home after both legislations. Moreover, after both Spanish smoke-free laws salivary cotinine concentration was homogenized according to sociodemographic variables. Copyright © 2017 Elsevier Ltd. All rights reserved.

The information available on antibiotic resistance patterns are generally based on specimens from hospitalised individuals. This study was aimed at evaluating the antibiotic resistance rate of nasal carriage strains of Staphylococcus aureus and Streptococcus pneumoniae in healthy individuals, in accordance with age and gender, attended in Primary Care Centres (PCC). Cross-sectional study. Seven PCC in the Barcelona area. Healthy nasal carriers aged 4years or more who did not present with any sign of infectious disease, and had not taken any antibiotic or had been hospitalised in the previous 3months. A total of 3,969 nasal swabs valid for identification were collected between 2010 and 2011 and were sent to one central microbiological laboratory for isolation of both pathogens. Resistance to common antibiotics was determined on the basis of the current European Committee on Antimicrobial Susceptibility Testing guidelines on cut-off points. The prevalence of methicillin-resistant S.aureus was 1.3% (95%CI: 0.5-2.1%), with resistance rates of 87.1% to phenoxymethylpenicillin and 11.6% to azithromycin, with no significant differences with age and gender. A total of 2.4% (95CI%: 0.1-4.7%) of the pneumococcal strains were highly resistant to both phenoxymethylpenicillin and macrolides, whereas the highest resistance rates were to cefaclor (53.3%), followed by tetracycline (20%) and cefuroxime (12.1%). These pathogens have lower resistance rates in the community than in the hospital setting. Primary Care physicians must be more aware of the current antimicrobial resistance, in order to ensure prudent use of antibiotics. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

Primary biliary cholangitis (PBC) is often associated with other autoimmune diseases, but little is known about the influence of thyroid disease (TD) on the natural history of PBC. Our aim is to analyze the association between PBC and TD, and the latter's impact on the natural history of PBC at two European centers. The study involved 921 PBC patients enrolled between 1975 and 2015 in Padova (376 patients) and Barcelona (545 patients), with a mean follow-up of 126.9±91.7 months. Data were recorded on patients' histological stage at diagnosis, biochemical data, associated extrahepatic autoimmune conditions, and clinical events, including hepatic decompensation. A total of 150 patients (16.3%) had TD, including 94 patients (10.2%) with Hashimoto's thyroiditis; 15 (1.6%) with Graves' disease; 22 (2.4%) with multinodular goiter; 7 (0.8%) with thyroid cancer; and 12 (1.3%) with other thyroid conditions. The prevalence of different types of TD was similar in Padova and Barcelona, except for Graves' disease and thyroid cancer, which were more frequent in the Padova cohort (15.7 vs. 5.0%, and 8.6 vs. 1.3%, respectively, P<0.05). Overall, there were no differences between PBC patients with and without TD in terms of their histological stage at diagnosis, hepatic decompensation events, occurrence of HCC, or liver transplantation rate. The presence of associated TD was not associated with lower survival for PBC patients in either cohort. TDs, and autoimmune TD like Hashimoto's thyroiditis in particular, are often associated with PBC, but the presence of TD does not influence the rate of hepatic complications or the natural history of PBC.

7Be behaviour and meteorological conditions associated with 7Be peak events in Spain.

Hernández-Ceballos, M A; Brattich, E; Lozano, R L; Cinelli, G

2017-01-01

This work regards a comprehensive analysis of the overall distribution of 7 Be activity concentrations in Spain and the synoptic meteorological conditions associated with the highest 7 Be peaks (>8 mBq/m 3 ). The use of four sampling stations (Barcelona, Bilbao, Madrid, and Sevilla) included in REMdb, with different latitudinal location, as well as the relatively long time period used in this study (2001-2010), allowed to improve the understanding of 7 Be spatio-temporal distribution in Spain. The comparison of the 7 Be activity concentrations mean values indicated a north-south gradient (from 3.1 ± 1.1 mBq/m 3 in Bilbao to 4.0 ± 1.8 mBq/m 3 in Sevilla), even though not statistically significant (as indicated by the t-test). However, the analysis of frequency distributions and temporal evolutions of 7 Be activity concentrations have suggested the presence of two main areas, namely northern (Bilbao and Barcelona) and southern (Sevilla) Spain. The identification and analysis of periods associated with the highest values of 7 Be have allowed studying the different synoptic patterns associated with stratospheric-tropospheric transport (STT). In particular, three episodes (one in the north and two in the south) potentially associated with vigorous STT have been identified and analysed in detail. The results displayed that the omega block configuration, extending either over western Russia and Scandinavia or into the Atlantic Ocean, forced the prevailing jet stream to the northeast and south of Spain respectively with subsequent subsidence. In summer, this blocking configuration at high latitudes was combined with the presence of the Azores high pressure system to the west of Spain, affecting the 7 Be activity concentration recorded in the south.

Laporte, J R; Tognoni, G

1985-01-01

In this case study from Nicaragua, an account is given of how the Essential Drugs Program developed in a context which relectss exceptional political, economic and military pressures. The overall picture could provide a useful guide to the issues behind such an apparently simple concept as the essential drugs list. The criteria for including drugs in the National Formulary were those of the WHO report on essential drugs: proven efficacy, acceptable risks associated with their use, favorable cost, and need. A proposal of the basic list of drugs, classified in therapeutic groups and according to their priority and level of use, was prepared by a central Committee for the National Drug Formulary. An annotated Formulary was prepared to ensure consistency with rigorous scientific standards and to meet the needs of daily practice. The annotated therapeutic formulary has been distributed to all physicians, other health workers responsible for peripheral health centers, pharmacists, and medical students. It has been adopted as the main reference textbook for teaching clinical pharmacology and therapeutics to medical students. A training program in clinical pharmacology has been started at the University Autonoma de Barcelona. It pays particular attention to drug evaluation, drug epidemiology methods, and retrieval and preparation of drug information for health workers.

Robotic liver surgery is the optimal approach as bridge to transplantation.

2017-02-08

The role of minimally invasive liver surgery as a bridge to transplantation is very promising but still underestimated. However, it should be noted that surgical approach for hepatocellular carcinomas (HCC) is not merely a technical or technological issue. Nowadays, the epidemiology of HCC is evolving due to the increasing role of non-alcoholic fatty-liver-disease, and the emerging concerns on direct-acting antivirals against hepatitis C virus in terms of HCC incidence. Therefore, a fully multidisciplinary study of the cirrhotic patient is currently more important than ever before, and the management of those patients should be reserved to tertiary referral hepatobiliary centers. In particular, minimally invasive approach to the liver showed several advantages compared to the classical open procedure, in terms of: (1) the small impact on abdominal wall; (2) the gentle manipulation on the liver; (3) the limited surgical trauma; and (4) the respect of venous shunts. Therefore, more direct indications should be outlined also in the Barcelona Clinic Liver Cancer model. We believe that treatment of HCC in cirrhotic patients should be reserved to tertiary referral hepatobiliary centers, that should offer patient-tailored approaches to the liver disease, in order to provide the best care for each case, according to the individual comorbidities, risk factors, and personal quality of life expectations.

Changing ecosystem service values following technological change.

Honey-Rosés, Jordi; Schneider, Daniel W; Brozović, Nicholas

2014-06-01

Research on ecosystem services has focused mostly on natural areas or remote places, with less attention given to urban ecosystem services and their relationship with technological change. However, recent work by urban ecologists and urban designers has more closely examined and appreciated the opportunities associated with integrating natural and built infrastructures. Nevertheless, a perception remains in the literature on ecosystem services that technology may easily and irreversibly substitute for services previously obtained from ecosystems, especially when the superiority of the engineered system motivated replacement in the first place. We emphasize that the expected tradeoff between natural and manufactured capital is false. Rather, as argued in other contexts, the adoption of new technologies is complementary to ecosystem management. The complementarity of ecosystem services and technology is illustrated with a case study in Barcelona, Spain where the installation of sophisticated water treatment technology increased the value of the ecosystem services found there. Interestingly, the complementarity between natural and built infrastructures may remain even for the very ecosystems that are affected by the technological change. This finding suggests that we can expect the value of ecosystem services to co-evolve with new technologies. Technological innovation can generate new opportunities to harness value from ecosystems, and the engineered structures found in cities may generate more reliance on ecosystem processes, not less.

Cultural Heritage in Smart City Environments

This paper investigates how the historical and cultural heritage of cities is and can be underpinned by means of smart city tools, solutions and applications. Smart cities stand for a conceptual technology-and-innovation driven urban development model. By becoming `smart', cities seek to achieve prosperity, effectiveness and competitiveness on multiple socio-economic levels. Although cultural heritage is one of the many issues addressed by existing smart city strategies, and despite the documented bilateral benefits, our research about the positioning of urban cultural heritage within three smart city strategies (Barcelona, Amsterdam, and London) reveals fragmented approaches. Our findings suggest that the objective of cultural heritage promotion is not substantially addressed in the investigated smart city strategies. Nevertheless, we observe that cultural heritage management can be incorporated in several different strategic areas of the smart city, reflecting different lines of thinking and serving an array of goals, depending on the case. We conclude that although potential applications and approaches abound, cultural heritage currently stands for a mostly unexploited asset, presenting multiple integration opportunities within smart city contexts. We prompt for further research into bridging the two disciplines and exploiting a variety of use cases with the purpose of enriching the current knowledge base at the intersection of cultural heritage and smart cities.

The use of granulocyte colony-stimulating factor (G-CSF) in the treatment of non-chemotherapy drug- induced agranulocytosis is controversial. We aimed at assessing the effect of G-CSF on the duration of agranulocytosis. To assess the effect of G-CSF on the duration of agranulocytosis, a Cox proportional hazard model with an estimated propensity score covariate adjusting for several prognostic factors was used. One hundred and forty-five episodes of agranulocytosis were prospectively collected from January 1994 to December 2000 in Barcelona (Spain). No differences were found in the case-fatality rate between treated (9 of 101, 8.9%) and not treated (5 of 44, 11.4%) patients. The median time to reach a neutrophil count > or =1.0 x 10(9)/L was 5 days (95%CI 5-6) in patients treated with G-CSF compared to 7 days (95%CI 6-8) in those not treated, with a hazard ratio of 1.58 (95% CI 1.1-2.3). G-CSF shortens time to recovery in patients with agranulocytosis. However, as an effect on case-fatality has not been recorded, and data on cost-effectiveness are lacking, it would be wise to restrict its use to high-risk patients.

Retrospective observational study. Four Primary Health Centres, Castellar del Vallès (Barcelona). 128 patients, 70 ACD and 58 PCC. Number of drugs at the time of death from the 6 selected group, deprescription (6 months prior to death due to advanced chronic disease), primary or secondary prevention and inappropriate prescription of PPI. Average age of 85'3 years (10,3). 40% took an antiplatelet drug, avoidable in 60% of the ACD, since they did not present any previous cardiovascular episode. 20% of the patients took statins, in which 48% of the cases were primary prevention. The PPI prescription was 67% with inadequate indication for use in 49% of these cases. 20% took calcium / Vitamin D and 1,6% of the ACD a bisphosphonate. There was a 16% deprescription. A high percentage of our patients with advanced chronic disease and short life expectancy still continue to take preventive and avoidable treatments, potentially dangerous due to their side effects. There is a need to reflect on what we do with these vulnerable patients. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

Climatic record of the Iberian peninsula from lake Moncortes' sediments Min Cao1, Carme Huguet1, Valenti Rull2, Blas L. Valero-Garces3, Antoni Rosell-Melé1,4 1Institut de Ciència i Tecnologia Ambientals (ICTA), Universitat Autònoma de Barcelona, 08193 Cerdanyola del Vallès, Catalonia, Spain; 2Institut de Botanic de Barcelona (CSIC), Passeig del Migdia s/n, 08038, Barcelona, Spain, 3 Instituto Pirenaico de Ecologıa (CSIC), Avda. Montañana 1005, 50059 Zaragoza, Spain, 4Institució Catalana de Recerca i Estudis Avançats (ICREA), 08010 Barcelona, Catalonia, Spain. The continuing buildup of industrial greenhouse gases in the atmosphere and concomitant increase in global temperatures has made much of the world's society aware that decades to centuries of environmental change lie ahead, and that these will have profound economic, political and societal impacts. The Iberian Peninsula lies in the boundary between tropical and subtropical climates and seems to amplify the climatic signals form the northern hemisphere through both atmospheric and water circulation feedbacks, making it an ideal site to monitor Northern hemisphere climate changes. This extreme sensitivity to climatic changes also makes the Iberian Peninsula extremely vulnerable to future climate changes. This is why understanding sensitivity to climate change and the consequences it will have on both climate and the hydrological cycle is key to implement preventive measures. The aim of our study is to come up with a high resolution quantitative reconstruction of climate variability (temperature, production and precipitation) in the Iberian Peninsula from lake sediments. We also want to establish the relation between those changes and the ones observed in both ice cores from Greenland and paleotemperature records from marine sediments of the continental Iberian margin. For these reasons we sampled a core in Moncortes (42.3N, 0.99E), a lake of karstic origin with an average depth of 25m and an area of 0.19km2. Lake Moncortes is situated at 1065 m above sea level, has an average temperature of 10ºC (minimum 3 and maximum 16ºC) and a mean annual precipitation of 770mm. We used the MBT/CBT (Weijers et al. 2007) proxy of pH and terrestrial temperature and the TEX86 temperature proxy (Schouten et al. 2002) to estimate changes in and around the lake. Both proxies are based on the glycerol dialkyl glycerol tetraethers (GDGTs) of archaea (isoprenoid GDGTs) and bacteria (branched GDGTs) origin. We also measured soils surrounding the lake (Menges et al. 2013) in order to establish end-members for the proxies as well as organic matter transport. Data on n-alkane isotopes will help establish hydrographic regime changes. We observe changes in temperature and humidity consistent with those on teh northern hemisphere. J. Menges, C. Huguet, J.M.

We investigated the etiology of reported sporadic suspected mumps cases with a negative RT-PCR result for the mumps virus in the Barcelona-South region in 2007–2011. Samples from mumps virus-negative patients presenting unilateral or bilateral parotitis or other salivary gland swelling were tested for Epstein-Barr virus (EBV) by real-time PCR and for respiratory viruses by two multiplex-PCR-based assays to detect parainfluenza virus (PIV) 1–4, influenza virus (InV) A, B and C, respiratory syncytial virus (RSV), enterovirus, coronavirus 229E, coronavirus OC43, and rhinovirus. 101 samples were analyzed in persons aged 8 months to 50 years. Oral samples were collected on the first day of glandular swelling in 53 patients (52.5%), and on the first two days in 74 patients (73.3%). Viruses were detected in 52 (51.5%) of samples: one virus (25 EBV, 8 PIV3, 4 adenovirus, 4 PIV2, 1 PIV1, 1 InVA, and 1 enterovirus) was detected in 44 patients (84.6%), two viruses in 7 patients, and three viruses in one patient. In 58 patients (57.5%) whose sample was collected in the first 2 days after onset of parotitis and had received two doses of MMR vaccine and in 15 patients (14.8%) whose sample was collected on the first day, it is very likely that the cause was not the mumps virus. This would mean that 72.3% (73/101) of the reported sporadic suspected mumps cases were not mumps cases. The timing of oral-sample collection is crucial to correctly interpret the negative results for mumps virus RNA, especially when suspected cases occur in vaccinated persons. PMID:25483547

Most of the studies on urinary iodine levels in Spain in the last decade have reported a significant improvement. A survey was undertaken together with an information campaign on the thyroid gland, the importance of iodine intake and hypothyroidism in four Spanish cities. The goals of the survey were to obtain information on consumption of iodine-containing foods, to measure urinary iodine levels and to evaluate the prevalence of thyroid dysfunction. A non-preselected population attending the information campaign centers located in Barcelona, La Coruña, Malaga and Madrid was studied. A questionnaire on fish, milk and iodized salt consumption was administered. Urinary iodine levels (Pino's method) and thyrotropin (TSH) concentrations (Whatman 903® dry paper method) were measured. A total of 872 questionnaires were completed (Madrid 40%; La Coruña 27%; Malaga 19%; and Barcelona 14%). The mean age was 51 years (SD 16); 81% were women. A total of 60.6% of interviewees reported they consumed iodized salt, 90.8% reported daily milk intake and 29.3% reported fish consumption ≥3 times per week. The mean urinary iodine concentration was 143.2 μg/L. The prevalence of high TSH levels (>4 mUI/L) was 1.3% and that of low TSH levels (<0.4 mUI/mL) was 1.2%. According to the World Health Organization criteria, the median urinary iodine concentration, both overall or by city, is indicative of optimal iodine intake. In addition to iodized salt intake, consumption of products such as milk and fish has probably contributed to these positive results. The prevalences of undiagnosed hyperthyroidism and hypothyroidism detected in this study were similar to those found in other studies. Copyright © 2010 SEEN. Published by Elsevier Espana.

2002-12-01

In light of the continuing spread of HIV infection and the devastating impact of the disease on lives, communities, and economies, particularly in the developing world, the investment in new treatments, vaccines, and microbicides has clearly been inadequate. Efforts must be intensified to develop effective HIV vaccines and to ensure that they are accessible to people in all parts of the world. This article is a summary of a paper by Sam Avrett presented at "Putting Third First: Vaccines, Access to Treatments and the Law," a satellite meeting held at Barcelona on 5 July 2002 and organized by the Canadian HIV/AIDS Legal Network, the AIDS Law Project, South Africa, and the Lawyers Collective HIV/AIDS Unit, India. In the article, Avrett calls for immediate action to increase commitment and funding for HIV vaccines, enhance public support and involvement, accelerate vaccine development, and plan for the eventual delivery of the vaccines. The article briefly outlines steps that governments need to take to implement each of these objectives. The article also provides a menu of potential actions for vaccine advocates to consider as they lobby governments.

The sagrada familia: A daily whisper of the spirit

Sounds from the top of the Temple; songs of loyals going beyond the city, sounds of the rustic forms of the spaces for the soul; reality and miracle in just one voice, voice of religion for participation; mystery, mysticism, meditation, happiness, music and songs, bells and church towers, choirs and pulpits, religion and city. The religious architecture of Gaudi is involved by mystic sounds, real or imaginary sounds, whispers almost imperceptibles and sonorous surprises in the journeys destined to peace and spiritual calm. The Sagrada Familia in Barcelona is a Temple where the sonorous itineraries will exist and where the acoustic design of choirs, bells and bell towers was an essential idea of Antoni Gaudi. A living building with its voice singing with the people a song which will take in the whole city; ringing bells and bell towers crossing the sky and sending music, view and hearing of all the people to the new cathedral, a symbol to guide pilgrimages, ceremonies, songs and festivals. The Sagrada Familia and Barcelona, a union that Gaudi wanted to turn in total and where the acoustic design will be transformed in a daily murmur, highly spiritual. (To be presented in Spanish.)

The occurrence of 166 emerging compounds and four heavy metals (Cd, Ni, Hg and Pb) in treated wastewater and groundwater has been monitored at the Llobregat delta (Barcelona, Spain) over a period of 3 years. Selected compounds were pharmaceuticals, personal care products (PCPs), dioxins, polycyclic aromatic hydrocarbons (PAHs) and priority substances included in the 2008/105/CE Directive. Analysis was performed in tertiary treated wastewater (TWW), after an additional treatment of ultrafiltration reverse osmosis and UV disinfection, and groundwater from a deep confined aquifer. This aquifer is artificially recharged with TWW through injection wells. After the advanced treatment, 38 pharmaceuticals, 9 PCPs, 9 pesticides and 7 PAHs still showed a frequency of detection higher than 25% in the TWW, although at low concentration levels (ng/l). Not all active compounds found in the TWW were present in groundwater, indicating possible degradation within the aquifer media after the injection. A number of chemicals, mainly 10 pesticides and 10 pharmaceuticals were only present in groundwater samples, confirming a different origin than the injected TWW, probably agricultural activities and/or infiltration of poorly treated wastewater.

The 26th conference of EGAS, the European Group for Atomic Spectroscopy, was held in Bellaterra (Barcelona), Spain, 12-15 July 1994. The conference was hosted by the Departament de Física, Universitat Autònoma de Barcelona, and brought together 216 participants from 29 countries. The program comprised 14 survey lectures by invited speakers and 230 contributed papers (45 oral and 185 posters). Applications of atomic spectroscopy are taking an increasingly important place in the EGAS conferences. This year a Symposium on Spectroscopy for Environmental Analysis was held during the meeting. Six of the survey lectures were presented at this Symposium. Thirteen of the invited lectures have been prepared for publication by the authors and are gathered in the present issue of Physica Scripta. The conference organizers thank all sponsors, especially the Spanish Direccción General de Investigación Científica y Técnica (DGICYT) and the Comisión Interministerial de Ciencia y Tecnología (CICYT), the Direcció General de Recerca (DGR) of the Generalitat de Catalunya, the Fundació Catalana per la Recerca, the Universitat Politècnica de Catalunya and the International Science Foundation (ISF), for supporting the 26th EGAS meeting.

In June 2006 the LISA International Science Team (LIST) accepted the bid presented by the Institut d'Estudis Espacials de Catalunya (IEEC) to host the 7th International LISA Symposium. This was during its 11th meeting at the University of Maryland, just before the 6th edition of the symposium started at NASA's Goddard Space Flight Center. The 7th International LISA Symposium took place in the city of Barcelona, Spain, 16-20 June, 2008, in the premises of CosmoCaixa, a modern science museum located in the hills near Tibidabo. Almost 240 delegates registered for the event, a record breaking figure compared to previous editions of the symposium. Many of the most renowned world experts in LISA, gravitational wave science, and astronomy, as well as engineers, attended LISA #7 and produced state of the art presentations, while everybody benefited from the opportunity to have live discussions during the week in a friendly environment. The programme included 31 invited plenary lectures in the mornings, and eight parallel sessions in the afternoons. These were classified into seven major areas of research: LISA Technology, LISA PathFinder, LISA PathFinder Data Analysis, LISA Data Analysis, Gravitational Wave Sources, Cosmology and Fundamental Physics with LISA and Other Gravitational Wave Detectors. Abstracts for 138 communications were received, from which a selection was made by the session convenors which would fit time constraints. Up to 63 posters completed the scientific programme. More details on the programme, including some of the talks, can be found at the symposium website:http://www.ice.cat/research/LISA_Symposium. There was, however, a remarkable add-on: Professor Clifford Will delivered a startling presentation to the general public, who completely filled the Auditori—the main conference room, 320 seats—and were invited to ask questions to the speaker who boldly guided them through the daunting world of Black Holes, Waves of Gravity, and other Warped Ideas of Dr Einstein. The Proceedings of the 7th International LISA Symposium are jointly published by the journal Classical and Quantum Gravity (CQG) and the Journal of Physics: Conference Series (JPCS). This formula has a precedent in the last Amaldi Conference (Sydney 2007), and was motivated by the impossibility to include all communications into a single CQG volume. Plenary speakers were invited to submit their contributions to CQG, as were a number of parallel session authors chosen by the session convenors and the Science Organising Committee (SOC). Authors of the other parallel session presentations and posters were invited to submit to JPCS. All papers have been peer-reviewed prior to being accepted for publication in either journal, and the whole set is a good representation of the talks we heard during the symposium. Thanks are accordingly due to all of the authors for their collaborative attitude and, more generally, to all of the delegates who came to Barcelona and made the symposium a first-class scientific event. The LISA community has been steadily growing since the symposium launched in Chilton, near Oxford (UK), back in 1996. The support of such community strongly endorses a complex mission project, whose short term future requires such support for a much longer term new era of gravitational wave astronomy and fundamental physics. In this sense, the number of attendees and their active interest in the LISA mission sparks optimism. The 7th International LISA Symposium sponsors are also sincerely acknowledged. They are: the Albert Einstein Institute (Hannover), the Spanish Ministry of Science and Innovation, the Generalitat de Catalunya (AGAUR), the Barcelona Institute of High Energy Physics (IFAE), the University of Barcelona (UB), the Polytechnique University of Catalunya (UPC), the Spanish Society of General Relativity and Gravitation (SEGRE), CosmoCaixa, NASA and the European Space Agency (ESA). The latter provided the LISA PathFinder model, a 1:4 scale model whose primer display we enjoyed during the symposium. Finally, the local organising committee (LOC) and the IEEC staff have given their enthusiastic support to the organization in every detail, and have worked efficiently for months to make the symposium happen. Many thanks to all of them, and congratulations. This is a co-publication with Journal of Physics Conference Series. A selection of papers are published in this issue of Classical and Quantum Gravity with the bulk of the papers, after peer review, published in Journal of Physics: Conference Series.

The Barcelona Clinic Liver Cancer (BCLC) algorithm is the standard system for clinical management of hepatocellular carcinoma (HCC). Data on adherence to this therapeutic paradigm are scarce. This field practice study aimed to provide a description of HCC cirrhotic patients in Southern Italy, to evaluate the adherence to BCLC guidelines and its impact on patients' survival. We analyzed the region-wide Italian database of Progetto Epatocarcinoma Campania, which includes data of HCC cirrhotic patients, prospectively collected from January 2013 to December 2015 in 16 regional centers. Overall, 1008 HCC patients were enrolled: 70.6% patients received therapies recommended by BCLC algorithm, while 29.4% underwent different treatments. Among patients who were treated in adherence to guidelines, a higher rate of diagnosis on surveillance programs, better liver function, lower rate of alpha-fetoprotein > 200 ng/mL, more early-stage and monofocal HCC, lower frequency of nodules > 5 cm, portal vein thrombosis and metastases were observed. The overall survival was evaluated according to HCC stage and no differences between groups and patients managed differently were found. The multivariate analysis showed that non-adherence to treatment guidelines was independently associated to the BCLC stage B, Child-Pugh classes B and C, and the presence of neoplastic thrombosis and metastases. Adherence to BCLC algorithm in field practice was high in early and end-stage HCC patients, but it was poor in intermediate and advanced patients. © 2017 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

The integration of information and communication technology into community pharmacists practice in Barcelona.

2014-03-01

The study aims to identify community pharmacists' (CPs) utilization of information and communication technology (ICT); to develop and characterize a typology of CPs' utilization of ICT and to identify factors that can enhance or inhibit the use of these technologies. An online survey of the 7649 members of the Pharmacist Association of Barcelona who had a registered email account in 2006 was carried out. Factor analysis, cluster analysis and binomial logit modelling were undertaken. Multivariate analysis of the CPs' responses to the survey (648) revealed two profiles of adoption of ICT. The first profile (40.75%) represents those CPs who place high emphasis on ICT within their practice. This group is therefore referred to as 'integrated CPs'. The second profile (59.25%) represents those CPs who make less use of ICT and so are consequently labelled 'non-integrated CPs'. Statistical modelling was used to identify variables that were important in predisposing CPs to integrate ICT with their work. From the analysis it is evident that responses to questions relating to 'recommend patients going on line for health information'; 'patients discuss or share their Internet health information findings'; 'emphasis on the Internet for communication and dissemination' and 'Pharmacists Professional Association information' play a positive and significant role in the probability of being an 'integrated CP'. The integration of ICT within CPs' practices cannot be adequately understood and appreciated without examining how CPs are making use of ICT within their own practice, their organizational context and the nature of the pharmacists-client relationship.

Food consumption frequency and excess body weight in adolescents in the context of financial crisis in Barcelona (Spain).

To describe food consumption frequency in adolescents in the context of the financial crisis in 2012, and to analyse potential fluctuations in excess body weight between 2008 and 2012. A cross-sectional study of eating habits and excess body weight was conducted in adolescents aged 13 to 19 years old from public, subsidised and private secondary schools in Barcelona, Spain. The FRESC lifestyle risk factors survey was used, and food frequency consumption, food recommendations and body mass index were analysed according to gender, year of education and socioeconomic status. Girls ate vegetables and fruits more frequently than boys, while the prevalence of junk food consumption was higher in boys. The prevalence of compliance with food recommendations was lower than 50% for all foods, and gender and socioeconomic differences were found for eggs, red meat and soft drinks. Regarding excess body weight, boys had a higher prevalence than girls in the 2 years analysed. Furthermore, a reduction in excess body weight was observed among girls in secondary education in the highest socioeconomic groups (28.7% [95% CI: 24.8-32.6%] in 2008 to 20.5% [95% CI: 17.1-23.8%] in 2012). The prevalence of adolescents following food recommendations is low, and gender differences were found in terms of food consumption frequency, even in the context of financial crisis. There is a need to promote programmes and policies to reduce inequalities related to eating habits and excess body weight in adolescents. Copyright © 2016 SESPAS.

They are oriented N-S to NNE-SSW and NNW-SSE at its northern and southern end, respectively, forming a subtle arc, oblique with respect to the general NW-SE trend of the Iberian Chain. The aim of this work is to characterize with paleomagnetic data the kinematic evolution of the the Altomira Range, located at the southwestern deformation front of the Iberian Chain, and of the structures within its associated piggy-back basin, the Loranca basin. This approach will also give clues regarding the primary and/or secondary origin of these structures to better characterize them in further studies (3D reconstruction and restoration, fault pattern). A total of 180 samples were obtained from 19 sites in Eocene, Oligocene and Miocene rocks (including clays, fine sandstones and limestones). They were analyzed by means of stepwise thermal demagnetization and subsequent measurement of the natural remanent magnetization (NRM). Although fold tests are not statistically significant, a primary origin of the magnetization is deduced by samples showing either normal or reverse polarity after bedding correction of the calculated characteristic components. Declinations of the site mean directions appear scattered after bedding correction suggesting differential vertical-axis rotations. Sites located at the northern and southern sectors display a clockwise rotation of 21 degrees and a counterclockwise rotation of 17 degrees, respectively. These results suggest that the present-day general orientation of the Altomira and Loranca structures respond to a progressive curvature, i. e. they were formed with N-S orientation, already oblique with respect to the NW-SE Iberian Chain trend, with a superimposed secondary deformation that slightly curved their originally linear trend.
