    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.

    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

    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.

    Research on biogenic volatile organic compound (BVOC) emissions has mainly focused on native species in natural ecosystems. However, much of the ozone and aerosol formation occurs in city atmospheres due to BVOC emissions by local urban vegetation. Plant composition of urban habitats is often dominated by non-native ornamental plant species, for which only limited data on BVOC emissions are available. To gain insight into the influence of ornamental vegetation on the urban atmospheric reactivity in Barcelona, Spain, we studied volatile isoprenoid emissions in 11 widespread ornamental tree species (three conifers and nine angiosperms). We found significant monoterpene emissions in all studied species, with normalized emission potentials (T=30 degrees C, photosynthetic photon flux density (PPFD)=1000 micromol x m(-2) x s(-1)) ranging between 0.2 to 110 microg x g(-1) (dry weight) h(-1). Depending on species, the emissions were dominated by alpha- and beta-pinene, myrcene, alpha- and beta-phellandrene, carene, limonene and eucalyptol. These data demonstrate that ornamental plants may significantly contribute to the BVOC load in urban atmospheres and also underscore the importance of broadleaf angiosperms as significant monoterpene emitters.

    Background Asbestos related diseases include a number of conditions due to inhalation of asbestos fibres at work, at home or in the environment, such as pleural mesothelioma, asbestosis and calcified pleural plaques. Few epidemiological studies have established the incidence of asbestos related diseases in our area. The present proposal is based on a retrospective study externally funded in 2005 that is currently taking place in the same area and largely carried out by the same research team. The aim of the study is to achieve a comprehensive and coordinated detection of all new cases of Asbestos Related Diseases presenting to primary care practitioners. Methods/design This is a multicentre, multidisciplinary and pluri-institutional prospective study. Setting 12 municipalities in the Barcelona province within the catchment area of the health facilities that participate in the study. Sample This is a population based study, of all patients presenting with diseases caused by asbestos in the study area. Measurements A clinical and epidemiological questionnaire will be filled in by the trained researchers after interviewing the patients and examining their clinical reports. Discussion Data on the incidence of the different Asbestos Related Diseases in this area will be obtained and the most plausible exposure source and space-time-patient profile will be described. The study will also improve the standardization of patient management, the coordination between health care institutions and the development of preventive activities related with asbestos exposure and disease.

    In recent years, Synthetic Aperture Radar (SAR) data have been widely used for scientific applications and several SAR missions were realized. The active sensor principle and the signal wavelength in the order of centimeters provide all-day and all-weather capabilities, respectively. The modern German TerraSAR-X (TSX) satellite provides high spatial resolution down to one meter. Based on such data SAR Interferometry may yield high quality digital surface models (DSMs), which includes points located on 3d objects such as vegetation, forest, and elevated man-made structures. By removing these points, digital elevation model (DEM) representing the bare ground of Earth is obtained. The primary objective of this paper is the validation of DEMs obtained from TSX SAR data covering Barcelona area, Spain, in the framework of a scientific project conducted by ISPRS Working Group VII/2 "SAR Interferometry" that aims the evaluation of DEM derived from data of modern SAR satellite sensors. Towards this purpose, a DSM was generated with 10 m grid spacing using TSX StripMap mode SAR data and converted to a DEM by filtering. The accuracy results have been presented referring the comparison with a more accurate (10 cm-1 m) digital terrain model (DTM) derived from large scale photogrammetry. The results showed that the TSX DEM is quite coherent with the topography and the accuracy is in between ±8-10 m. As another application, the persistent scatterer interferometry (PSI) was conducted using TSX data and the outcomes were compared with a 3d city model available in Google Earth, which is known to be very precise because it is based on LIDAR data. The results showed that PSI outcomes are quite coherent with reference data and the RMSZ of differences is around 2.5 m.

    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.

    Background The aim of the present study is to evaluate the impact of glucose-lowering agents in the risk of cancer in a large type 2 diabetic population. Methods A nested case-control study was conducted within a defined cohort (275,164 type 2 diabetic patients attending 16 Primary Health Care Centers of Barcelona). Cases (n = 1,040) comprised those subjects with any cancer diagnosed between 2008 and 2010, registered at the Cancer Registry of Hospital Vall d'Hebron (Barcelona). Three control subjects for each case (n = 3,120) were matched by age, sex, diabetes duration, and geographical area. The treatments analyzed (within 3 years prior to cancer diagnosis) were: insulin glargine, insulin detemir, human insulin, fast-acting insulin and analogues, metformin, sulfonylureas, repaglinide, thiazolidinediones, dipeptidyl peptidase-4 inhibitors, and alpha glucosidase inhibitors. Conditional logistic regressions were used to calculate the risk of cancer associated with the use of each drug adjusted by age, BMI, dose and duration of treatment, alcohol use, smoking habit, and diabetes duration. Results No differences were observed between case and control subjects for the proportion, dose or duration of exposure to each treatment. None of the types of insulin and oral agents analyzed showed a significant increase in the risk of cancer. Moreover, no cancer risk was observed when glargine was used alone or in combination with metformin. Conclusions Our results suggest that diabetes treatment does not influence the risk of cancer associated with type 2 diabetes. Therefore, an eventual increase of cancer should not be a reason for biasing the selection of any glucose-lowering treatment in type 2 diabetic population. PMID:24278227

    Arbovirus infections are a group of diseases whose incidence is increasing and that entail an important problem for public health. The aim of this study was to describe detected cases of arbovirosis in Barcelona, and surveillance and control actions performed in order to reduce the risk of transmission. Descriptive cross-sectional study of confirmed dengue, chikungunya and Zika cases in Barcelona during 2014-2016 (1st trimester). Suspected cases detected in the city were notified to the Epidemiology Department of the Barcelona Public Health Agency, where an epidemiological survey is undertaken and, if appropriate, Urban Pests Surveillance and Control Department is contacted. They perform an entomological inspection and implement control and monitoring actions. We collected sociodemographical, epidemiological, clinical and entomological variables. In 2014, 50 chikungunya and 20 dengue cases were detected; 25 entomological inspections were carried out in residences and 38 in the street. In 2015, 47 chikungunya, 51 dengue and 2 Zika cases were detected; 27 inspections were carried out in residences and 80 in the street. In 2016, 17 chikungunya, 52 dengue and 48 Zika cases were detected; 50 inspections were carried out in residences and 103 in the street. No autochtonous case was detected. We observed an increasing incidence of arbovirosis cases during the 3-year study period. There was a progressive intensification of vector surveillance and control actions (inspections, sample collection…).

    To describe the cases of AIDS detected in a Barcelona prison. A prospective study. A penitentiary for men in Barcelona. All those inmates who had AIDS or were diagnosed with the illness during their stay in prison during the 36 months between 1/1/1991 and 31/12/93. 220 cases of AIDS (91.7% PVDA), 60% of which were diagnosed in prison. The PVDA were younger (p < 0.0001). There were a greater number of Spaniards among the UDVP (p < 0.01) and among those with tattoos (p < 0.001). The first manifestation of the disease in 53% of the cases was extrapulmonary Tuberculosis. Prisons are key places in the prevention and monitoring of HIV infection. The use of care programmes, including maintenance programmes using Methadone, for drug-dependent patients are recommended. The continuation of programmes tracking Tuberculosis, the main illness related to HIV infection in prison, is also recommended.

    To determine the frequency and characteristics of suspected drug-facilitated sexual assault (DFSA) among the victims of sexual assault in Barcelona. Prospective study of every adult consulting an emergency service because of alleged sexual assault and receiving forensic assessment in the city of Barcelona in 2011. A total of 35 of 114 cases (30.7%) met suspected DFSA criteria. Compared with the other victims, suspected DFSA cases were more likely to experience amnesia, to have been assaulted by night, after a social situation and by a recently acquainted man, to have used alcohol before the assault and to be foreigners. In this group ethanol was detected in blood or urine in 48.4% of analyzed cases; their mean back calculated blood alcohol concentration was 2.29g/l (SD 0.685). Also, at least one central nervous system drug other than ethanol was detected in 60,6%, mainly stimulant drugs of abuse. Suspected DFSA is frequent among victims of alleged sexual assault in Barcelona nowadays. The depressor substance most commonly encountered is alcohol, which contributes to victims' vulnerability.

    Pertussis remains an important cause of morbimortality despite current vaccination strategies. This study was designed to describe the results and characteristics of close contacts of pertussis cases diagnosed in children less than 16 years in a tertiary hospital in Barcelona. Cross-sectional study. Data were collected from chart review of contacts of paediatric cases of pertussis in Vall d'Hebron University Hospital from 2005 to 2009. Only patients with microbiological study done were included. The odds ratio (OR) and 95% confidence interval (95% CI) were calculated as association measure. Ninety-one index cases and 404 contacts were studied. The prevalence of positive cases among contacts was 33.2%. Contacts of index cases younger than 6 months had a higher risk of being positive for pertussis than contacts of older children (OR: 3.38; 95% CI: 1.88-6.10). Primary cases were identified as 16.7% of the contacts studied, who were the source of infection for 67.7% of index cases younger than 6 months and for 26.9% of older index cases. Contact tracing of paediatric pertussis cases is a necessary clinical activity. It is more likely to find primary cases in the contact investigation of children less than 6 months. Preventive strategies should be targeted primarily to frequent contacts of this age group. Copyright © 2012 Elsevier España, S.L. All rights reserved.

    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

  20. Urban and peri-urban flood impact change: the case of the Metropolitan Area of Barcelona

    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

    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.

    The aim of this study was to determine the evolution of HIV infection, gonorrhea, syphilis and lymphogranuloma venereum (LGV), and their epidemiological characteristics in Barcelona city. Population-based incidence study of all newly occurring diagnoses of HIV infection, syphilis, gonorrhea and LGV detected in Barcelona between January 2007 and December 2011. A descriptive analysis was performed. The annual incidence rates per 100,000 inhabitants were calculated by sex, sexual conduct and educational level. To estimate global sex-specific rates we used the Barcelona city census; for the calculation of rates by sexual conduct and educational level we used estimates of the Barcelona Health Interview Survey. Trends were analysed using the chi-squared test for linear trend. HIV. 66.8 % of the HIV cases were men who had sex with men (MSM). The incidence rates in MSM over the study period were from 692.67/100,000 to 909.88/100,000 inh. Syphilis. 74.2 % of the syphilis cases were MSM. The incidence rates in MSM were from 224.9/100,000 to 891.97/100,000 inh. and the MSM with a university education ranged from 196.3/100,000 to 1020.8/100,000. Gonorrhea. 45.5 % of the gonorrhea cases were MSM. The incidence rates in MSM were from 164.24/100,000 to 404.79/100,000 inh. and the MSM with university education ranged from 176.7/100,000 to 530.1/100,000 inh.. Lymphogranuloma venereum (LGV). 95.3 % of the LGV cases are MSM. The incidence rates in MSM were from 24.99/100,000 to 282.99/100,000 inh. and the MSM with university education ranged from 9.3/100,000 to 265/100,000 inh. An increase in cases of STI was observed. These STI mainly affected MSM with a university education. Continuing to monitor changes in the epidemiology of STI, and identifying the most affected groups should permit redesigning preventive programs, with the goal of finding the most efficient way to reach these population groups.

    A follow-up study of 73 heroin-addicted persons three years after their first visit for treatment in 1981 to the Department of the Prevention of Drug Dependence and Guidance and Treatment of Drug Dependent Persons at Barcelona, Spain, was compared to a study of the same persons carried out after one year. The comparison showed that after one year 37 per cent of the cases had a favourable and 36 per cent an unfavourable outcome; for 27 per cent of the cases, information was lacking. After three years, 56 per cent showed a favourable and 30.3 per cent an unfavourable outcome; for 13.7 per cent information was lacking. Certain factors, such as a longer duration of treatment, a change in residence from an urban to a rural environment and treatment in a therapeutic community, were found to have enhanced the likelihood of achieving favourable results. Detoxification when not supplemented with supportive measures aimed at rehabilitation had a poor outcome.

    Recent epidemiological research suggests that short-term effects of particle matter (PM) in urban areas may preferentially be driven by fine fractions. Questions remain concerning the adversehealth effects of coarse particles generated by noncombustion, traffic-related processes and the mechanism of action of PM. Using a time-stratified case-crossover design, we investigated the association between three independent size fractions, coarse (PM10-2.5), intermodal (PM2.5-1), and very fine PMs (PM1), and three health outcomes, respiratory, cardiovascular, and cerebrovascular mortality in Barcelona, Spain, during the period of March 2003-December 2005. Using existing data, we examined the chemical composition of each fraction to explore the effects of PM from different sources and the mechanisms of action. We found that increased levels of PM, and PM10-2.5 were associated with increased levels of cardiovascular and cerebrovascular mortality at lag 1 and lag 2. At lag 1, the odds ratio (OR) for a 1 microg/m3 increase in PM1 was 1.028 [95% confidence interval (CI), 1.000-1.058] for cardiovascular mortality and 1.063 (95% CI, 1.004-1.124) for cerebrovascular mortality. At lag 1, the odds ratio per a 10 microg/ m3 increase of PM10-2.5 was 1.059 (95% CI, 1.026-1.094) for cardiovascular mortality and 1.098 (95% CI, 1.030-1.171) for cerebrovascular mortality. Association with respiratory mortality was only detected for PM2.5-1 at lag 2 (OR, 1.206 per a 10 microg/ m3 increase; 95% CI, 1.028-1.416). Chemical composition data showed that PM in Barcelona was generated in a large proportion by vehicle traffic. Vehicle traffic PM, generated by combustion and noncombustion processes, should be considered in air pollution mitigation strategies in urban areas.

    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.

    The use of Enteral Nutrition at Home (ENH) in the Hospital Clínico de Barcelona has grown greatly over the last decade, with a certain trend towards stabilization being observed in the last two years, but still growing at a rate of 9.2% per annum. A transverse analysis of the active patients on our ENH register at a given moment has revealed a total of 315 patients receiving treatment. The retrospective analysis of our series during 1998 gave a figure of 643 new cases. The most frequent indication for ENH was neoplasia (44%), followed by neurological pathology (28%). The administration route most frequently used was oral (66% of cases). In the oral route, oncological diagnoses were dominant (52%), whereas administration by means of a naso-gastric tube was mainly due to neurological disorders (72%). The use of PEG (12.5% of administrations via tube) was distributed between oncological and neurological patients, with a slight predominance of the first. Of those patients completing ENH in the same year, duration was in most cases (67%) less than one month. The decrease of the patient due to the underlying disorder was the main cause of termination, followed by the need for short-term nutritional support following discharge from hospital.

    The aim of this study is to describe inequalities in socioeconomic indicators and in mortality by sex in the census tracts of Barcelona city during the period 1996-2003. The results show that there is excess mortality in coastal and northern areas. This distribution is similar to that of socioeconomic deprivation and therefore there is an association between mortality and socioeconomic indicators, not only for total mortality but also for the specific causes of death studied. This type of analysis can be useful for planning of public health policy since it allows small areas with high mortality risk to be detected.

    The Ground-penetrating radar (GPR) analysis of some modernist buildings of the Technical Industrial School of Barcelona allow us to obtain valuable information of the underground constructions, corresponding to ancient structures of the preceding factory. The actual school is building on the modernist industrial complex. Many changes in the structure were carried out to adapt the structure to its actual use. The obtained GPR data was compared with the information, documents and photographies from the historical archives of the Diputación of Barcelona (Spain). To obtain accurate results and right interpretations, velocity analysis is performed in the different studied areas. The velocity values are used to convert accurately the two-way travel time into depth. The aim of those velocity estimations is obtain the minimum error in the final interpretations of the profiles. The velocity analysis is carried out using two different methods: calculating velocity using the reflection in anomalous bodies into the medium at a known depth, and calculating velocity from the hyperbolic events of the radargrams, caused by finite anomalies of the medium. The present tubes and conductions which are in use nowadays, have known depths. Then, velocity is obtained from the two-way travel time obtained for the reflected wave in that anomalous body. This method allow us to known velocities in areas where those elements are presented, which are mainly in the ground under the streets of the school. The reflection produced in unknown bodies which have finite dimensions, is obtained as an hyperbolic event. The averaged velocity of the medium over these bodies is calculated from the equation of the hyperbola. This method was used mainly where known elements were not presents in the ground. These areas are mainly the buildings of the school. Experimental velocities are understand as the averaged velocity of ray-path. The obtained values are applied to each area, to calculate depths of the

    2007-01-01

    The purpose of this article is to determine the differences and similarities between adolescents from Barcelona and Bogotá in their psychoactive substance use habits, their perception of the activities that involve this use and how their risk perception can influence these habits. The sample consists of 865 school students from both cities, with ages between 15 and 18 years. Risk perception was assessed using the risk variables studied by Benthin, Slovic and Severson (1993). Substance use habits were assessed on the basis of the answers given by the youngsters to questions on the age when they first used any substance, frequency of use in the last week and use intentions in the next year. The findings suggest that the age they begin to use alcohol and marijuana and the first time they get drunk differ significantly between the adolescents in the two cities. The Barcelona youngsters have a higher tendency and actual use in respect of all the substances studied than the Bogotá youngsters. Perceived pleasure or benefits predict an increase in both the intention and frequency of use for almost every substance in this study for all, with the exception of the older adolescents (17 to 18 year-olds) from Bogotá. Fear of the consequences or the perception of a risk of illness or injury and conditions favouring use do not seem to have an obvious influence on the various use habits.

  15. 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

    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.

    This paper presents an observational study of the tornado outbreak that took place on the 7 September 2005 in the Llobregat delta river, affecting a densely populated and urbanised area and the Barcelona International airport (NE Spain). The site survey confirmed at least five short-lived tornadoes. Four of them were weak (F0, F1) and the other one was significant (F2 on the Fujita scale). They started mostly as waterspouts and moved later inland causing extensive damage estimated in 9 million Euros, three injured people but fortunately no fatalities. Large scale forcing was provided by upper level diffluence and low level warm air advection. Satellite and weather radar images revealed the development of the cells that spawned the waterspouts along a mesoscale convergence line in a highly sheared and relatively low buoyant environment. Further analysis indicated characteristics that could be attributed indistinctively to non-supercell or to mini-supercell thunderstorms.

    The cleanup of contaminated places with heavy metals is necessary, but environmental remediation strategies are often expensive and energy consuming. Thus, it is important to develop low-cost and environmentally friendly strategies. Phytoremediation-based technologies could provide a long-lasting solution. The study area is located in Sants, a neighbourhood in Barcelona city (Catalonia, Spain). This place was an industrial area in the last century, which was occupied by a metal smelting industry. Nowadays, the neighbours want to cultivate vegetables in this location, but the history of this area suggests that the soil is polluted by elevated concentrations of heavy metals. The aim of this work was to determine heavy metal concentration in: a) soil, to know the degree of the soil pollution; b) roots and leaves of two plant species, Brassica juncea as an accumulator plant and Solanum lycopersicum as a crop plant, to know the capacity of each species to accumulate metals, and c) drainage water, to evaluate the heavy metal mobility. The main pollutants are Cu, Pb and Zn with topsoil total concentrations about 1355, 2230 and 6239 mg•kg-1, respectively. The established background upper limits in this area in mg•kg-1 were: Cu 145, Pb 91 and Zn 326. The same soil elements for available fractions, extracted with DTPA, were slightly elevated (9.6, 5.8 and 6.7 % of total concentration). The environmental pollution implies great extractability, suggesting the plants in these soils have facility with potentially toxic elements absorption. Instead, the concentrations in subsoil are lower than in topsoil. The concentrations of Cu, Pb and Zn in the plants' leaves are greater in B. juncea 170 ± 52.7, 137 ± 46.3 and 2365 ± 860.4 mg•kg-1, than in S. lycopersicum 102.5 ± 7.1, 22.5 ± 1.3 and 1002 ± 85.2 mg•kg-1 respectively. Furthermore, they are also greater in roots than in leaves. All of them are lower than the threshold to be considered like a hyperaccumulator species

    The aims of this multicenter study was to establish the level of primary and acquired drug resistance of M. Tuberculosis strains isolated in Barcelona and to identify possible risk groups using clinical data. All tuberculosis patients with isolation and identification of M. tuberculosis strains from October 1995 to September 1997 were included. Susceptibility tests isoniazid, rifampin, ethambutol, streptomycin and pyrazinamide were performed using the Bactec 460 system and the proportions method on solid medium. Logistic progression was used for statistical analysis. The total number of patients included was 1,749 (1,535 non-treated and 214 previously treated). Primary drug resistance was 5.7% (isoniazid 3.8%; rifampin 1.0%, streptomycin 2.1%, ethambutol 0.3% and pyrazinamide 1.0%). Acquired drug resistance was 20.5% (isoniazid 17.3%, rifampin 9.8%, ethambutol 1.9%, streptomycin 4.7% and pyrazinamide 6.5%). Primary drug resistance was associated with people over 60 years old and women. The low level of drug resistance enables antituberculosis treatment of non-treated patients to start with the standardised three-drug regimes except in the case of foreign people from countries with a high level of drug resistance. Susceptibility tests are recommended on all M. tuberculosis strains isolated, together with controlled studies of drug resistance surveillance.

    The abbreviated Barcelona Test (a-BT) is an instrument widely used in Spain and Latin American countries for general neuropsychological assessment. The purpose of the present study was to provide new norms for the a-BT as part of the Neuronorma project. The sample consisted of 346 healthy controls. Overlapping cell procedure and midpoint techniques were applied to develop the normative data. Age, education, and sex influences were studied. Results indicated that although age and education affected the score on this test, sex did not. Raw scores were transformed to age-adjusted scaled scores (SS(A)) based on percentile ranks. These SS(A) were also converted into age-education scaled scores using a linear regression model. Norms were presented on age-education scaled scores. Also, the a-BT cognitive profile was presented and should prove to be clinically useful for interpretation. These co-normed data will allow clinicians to compare scores from a-BT with all the tests included in the Neuronorma project.

    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

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.

    Austerity policies implemented in Spain in response to the ongoing economic crisis may have detrimental consequences for the health of immigrant populations and for public health in general. A mixed-methods study by the Public Health Agency of Barcelona and the University of Michigan indicates that the Real Decreto-ley 16/2012 (RDL) threatens the health of individuals and the population, especially in the case of infectious diseases. The study sought to determine the percentage of foreign-born persons with an infectious disease who had an Individual Health Card (IHC) prior to the RDL and to determine whether foreign-born persons with an infectious disease in Barcelona encountered problems accessing health care after the RDL. Results indicate that immigrants used the IHC to seek medical attention for infectious diseases and chronic conditions. Results also show that 66% of respondents, including 54% of unemployed respondents, 3% of respondents working without contracts, and those in informal employment (9%), may be at risk of losing at least part of their health coverage. Universal health care access in Spain has been crucial for the control of communicable diseases among immigrant populations. Reducing access to a significant percentage of the total population may have deleterious effects on public health. © The Author(s) 2016.

    The short version of the Barcelona Test is a clinical tool that covers a wide spectrum of neuropsychological skills. Since its creation in 1977, it has often been subject of study either for its internal aspects or in validation studies with other cognitive tests. The results indicate that the Barcelona Test is a useful instrument in detecting cognitive impairment. The aim of this study is to measure the testretest reliability and the interrater reliability of the Abbreviated Barcelona Test in normal population. the sample consists of 31 normal subjects (14 men and 17 women) from 20 to 65 years old. Abbreviated Barcelona Test (TBA), Mini-Mental Status Examination (MMSE), Syndrome-Kurztest (SKT) and Interview for Deterioration of Daily living in Dementia (IDDD). descriptive statistics and intraclass correlation coefficient. Test-retest reliability shows good intraclass correlation coefficients with both direct ICC=0.92 (IC 95%: 0.85-0.96) or typified scores ICC=0.79 (IC 95%: 0.61-0.89). Nevertheless, when each of the subtests is considered, correlations clearly show two characteristics: subtest with no or minimal range of scores and subtest with distribution of scores (as is the case of memory and executive function). The intraclass coefficient found for the interrater reliability is ICC =0.99 (IC 95 %: 0.99-0.99) and an alpha of 0.99 which indicate excellent reliability. As a whole, the abbreviated version of the Barcelona Test has excellent test-retest and interrater reliability psychometric characteristics.

    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

    Quantitative and qualitative studies were made of the fungi of the air in Barcelona City. The genera Cladosporium and Alternaria formed two of the most important components of the fungus population studied during a two-year period running from January 1976 through January 1978. Penicillium species formed the 16.3% of the total colonies while Aspergillus species represented only the 2.8%. The occurrence of the genera was greatly affected by climatic conditions. An attempt was made to summariza the data of various kinds of fungi on a volumetric basis. Most of the fungi reported here have been identified as far as genera.

    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.

    designing a new curriculum in Physics. His main argument perhaps was that a physics course should be designed as a set of narratives, with beginning, middle, end and a point, rather than as a set of concepts whose meaning was of more significance to the teacher or curriculum designer than to the students. He was followed by Ed Redish of the University of Maryland, another entertaining speaker who addressed the global problem of the decline in the number of students willing to study physics when given a free choice not to do so. His talk was wide ranging, but centred on the apparent fact that physics teaching was essentially unsuccessful - for a variety of reasons. He proposed that this was a problem that could and should be tackled scientifically, with a loop of research-instruction-design. Science is good at solving problems, but so far physics hasn't seen physics teaching and learning as problematic. Maybe physics lecturers are so good at physics that difficulty in learning it is taken to be a student problem (inattention, sheer stupidity) rather than a systemic one. I look forward to hearing more about this. What I did get from one or two lectures about research into the way teachers failed tended to raise my blood pressure to dangerous levels. In both cases considerable skill and effort had been put into finding out that curriculum innovations or new teaching techniques had been badly handled by teachers, who had still kept to their old ways - like using ray boxes in optics work, or failing to make best use of Real Time laboratory systems (i.e. data logging). These new approaches were described as expert-designed innovations. I am afraid that it occurred to me that if experts had been employed to produce a new production system in a factory failure of the workforce to implement it would have resulted in some high-level expert redundancies. Certainly not `more research' as was advocated here. But it wasn't all grief: many talks and lectures were inspiring and showed how

    Descriptive analysis of some features in patients with cranio-encephalic traumatisms (CET) admitted to our hospital and collected in a data base, in order to establish the prognosis of the lesions and apply the most appropriate diagnostic and therapeutic procedures. Since July 1987 to June 1989 we collected data on 584 patients with CET who presented the following selection criteria: consciousness level lower than 13 points in the Glasgow scale and/or pathologic computerized tomography. According to the consciousness level (Glasgow scale) on admission, patients were classified into three groups: slight CET (Glasgow 15-13), moderate CET (Glasgow 12-9), and severe CET (Glasgow < 9). The traumatic mechanisms were divided into 8 categories (occupant, pedestrian, motorbike, aggression, labor, drop, sporting, cyclist). According to the main lesion we considered the following diagnoses: subdural hematoma, epidural hematoma, cerebral contusion (s), diffuse lesion with normal computerized tomography and/or subarachnoid hemorrhage, cerebral congestion, and diffuse axonal lesion. Results were evaluated six months after using the Glasgow scale. The mean age of patients with slight CET was 37.7 +/- 22.1 years, those with moderate CET 31.7 +/- 22.6 years, and those with severe CET 30.8 +/- 21.6 years. Four hundred and forty-two were men (75.6%). The time period between the accident and hospital admission could be determined in 512 cases (87.6%). Severe CET arrived to the hospital (4.8 +/- 7.3 hours) earlier than the other groups (6.6 +/- 11.9 hours in moderate CET and 14.2 +/- 23 hours in slight CET). Most of patients, 488 (83.5%), were referred from another hospital, whereas the remaining cases came directly from the accident place. Traumatic mechanisms according to the previous categories were: occupant 145 (25%), pedestrian 112 (20%), motorbike 104 (18%), cyclist 2 (0.003%), labor 39 (7%), drop 154 (27%), sporting 7 (1%), aggression 10 (2%).

    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.

    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

    Background Cryptosporidium infection is a worldwide cause of diarrheal disease. To gain insight into the epidemiology of the infection in a certain geographic area, molecular methods are needed to determine the species/genotypes and subtypes. Methodology/Principal Findings From 2004 to 2009, 161 cryptosporidiosis cases were detected in two hospitals in Barcelona. Diagnosis was performed by microscopic observation of oocysts in stool specimens following modified Ziehl-Neelsen staining. Most cases (82%) occurred in children. The number of cases increased in summer and autumn. Molecular characterization of Cryptosporidium was performed in 69 specimens, and C. hominis and C. parvum were identified in 88.4% and 10.1% of the cases, respectively. C. meleagridis was detected in one specimen. Subtyping based on the gp60 polymorphism showed six subtypes, four C. hominis and two C. parvum. Subtype IbA10G2 was the most prevalent subtype corresponding to 90% of all C. hominis isolates. This is the first report on the distribution of specific Cryptosporidium subtypes from humans in Spain. Conclusions/Significance In our geographic area, the anthroponotic behavior of C. hominis, the lower infective dose, and the higher virulence of certain subtypes may contribute to the high incidence of human cryptosporidiosis caused by the IbA10G2 subtype. Further studies should include populations with asymptomatic shedding of the parasite. PMID:25816024

    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.

    Mounting research highlights the contribution of ecosystem services provided by urban forests to quality of life in cities, yet these services are rarely explicitly considered in environmental policy targets. We quantify regulating services provided by urban forests and evaluate their contribution to comply with policy targets of air quality and climate change mitigation in the municipality of Barcelona, Spain. We apply the i-Tree Eco model to quantify in biophysical and monetary terms the ecosystem services "air purification," "global climate regulation," and the ecosystem disservice "air pollution" associated with biogenic emissions. 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.

    Strongyloides stercoralis infection in patients with HTLV-I infection may lead to severe clinical manifestations. The aim of the present study is to determine the seroprevalence of S. stercoralis infection among blood donors who tested positive for HTLV-I infection. A cross-sectional study was performed at the Vall d'Hebron University Hospital (Barcelona, Spain) in 2016. Serum samples from HTLV-I positive patients diagnosed from 2008 to 2015 were retrieved from the Blood Bank, and S. stercoralis serology was performed. Thirty six serum samples from HTLV-I positive patients were retrieved from the Blood Bank. The blood samples came from 36 blood donors, and most of them were born in Latin America (75%), being Peru the most frequent country (11 participants). S. stercoralis serology was positive in one patient, corresponding to a prevalence of 2.8% (3.4% if we exclude donors coming from European countries, where the risk of S. stercoralis infection is highly unlikely).

    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.

    Objective To describe the voluntary adoption of smoke-free homes in Spain among general population and to identify variables associated with its voluntary adoption. Methods Cross-sectional study of a representative sample (n=731) of the adult population (>26 years) of Barcelona, Spain, in 2013–2014. We defined smoking rules inside the households as complete indoor rules (when smoking was not allowed inside the house), and partial or absent indoor rules (when smoking was allowed in some designated places inside the house or when smoking was allowed everywhere) and described them according to the perceived risk of the secondhand smoke (SHS) exposure. We calculated the prevalence and prevalence ratios (PR) according to sociodemographic variables. Results 57.4% of households had complete indoor smoke-free rules. The prevalence of households with complete indoor rules was higher among women (PRa: 1.15; 95% CI 1.00 to 1.33), married (PRa: 1.18; 95% CI 1.01 to 1.38), never-smokers (PRa: 2.68; 95% CI 2.06 to 3.50) and in households where a minor lived (PRa: 1.40; 95% CI: 1.20–1.65). Believe that breathing tobacco smoke from smokers is dangerous for non-smokers (PRa: 1.77; 95% CI: 1.06–2.97) is associated with the voluntary adoption of complete indoor smoke-free home. Conclusions Risk perceptions of SHS exposure were associated with the voluntary adoption of indoor smoke-free homes. PMID:28104712

    Due to the high rates of antimicrobial resistance to certain antibiotics, together with the emergence of Neisseria gonorrhoeae (NG) with reduced susceptibility and resistance to third-generation cephalosporins, gonococcal infection is becoming a public health problem. The objectives of the study were: To keep track of the antimicrobial susceptibility of NG strains obtained from January to August 2011. To study the population dynamics. The antimicrobial susceptibility was studied by disk-diffusion and E-test. The genotyping was performed by NG-MAST method. Of a total of 100strains studied, 59% showed intermediate sensitivity to penicillin and 9% were resistant. According to EUCAST, we detected 3gonococci with reduced susceptibility to ceftriaxone, 10 to cefixime and one with high-level resistance to both antibiotics (MIC 1.5μg/ml). MIC50 and MIC90 to cefixime were 0.016 and 0.125μg/ml, respectively, whereas to ceftriaxone they were <0.016 and 0.064μg/ml, respectively. Almost all (99%) of the strains were resistant to doxycycline, 53% to ciprofloxacin, 3% to azithromycin, and 1% to spectinomycin. The most prevalent ST was ST1407, predominantly associated to resistance or reduced sensitivity to cephalosporins or macrolides. NG has developed significant rates of resistance to various antibiotics. One strain has been detected with high level resistance to third generation cephalosporins, and several strains with reduced susceptibility. An increase in MIC50 and MIC90 to these antibiotics has also been observed. NG population structure remains stable and common to the rest of Europe, although two new ST (ST7226 and ST7227) have been identified that could be selected and acquire high levels of resistance to cephalosporins.

    Alzheimer's disease (AD) is among the most significant health care burdens. Disappointing results from clinical trials in late-stage AD persons combined with hopeful results from trials in persons with early-stage suggest that research in the preclinical stage of AD is necessary to define an optimal therapeutic success window. We review the justification for conducting trials in the preclinical stage and highlight novel ethical challenges that arise and are related to determining appropriate risk-benefit ratios and disclosing individuals' biomarker status. We propose that to conduct clinical trials with these participants, we need to improve public understanding of AD using unified vocabulary, resolve the acceptable risk-benefit ratio in asymptomatic participants, and disclose or not biomarker status with attention to study type (observational studies vs clinical trials). Overcoming these challenges will justify clinical trials in preclinical AD at the societal level and aid to the development of societal and legal support for trial participants.

    Using Barcelona and Shanghai as case studies, we examined the nature-based solutions (NBS) in urban settings-specifically within cities experiencing post-industrialization and globalization. Our specific research questions are: (1) What are the spatiotemporal changes in urban built-up land and green space in Barcelona and Shanghai? (2) What are the relationships between economic development, exemplified by post-industrialization, globalization, and urban green space? Urban land use and green space change were evaluated using data derived from a variety of sources, including satellite images, landscape matrix indicators, and a land conversion matrix. The relationships between economic development, globalization, and environmental quality were analyzed through partial least squares structural equation modeling based on secondary statistical data. Both Barcelona and Shanghai have undergone rapid urbanization, with urban expansion in Barcelona beginning in the 1960s-1970s and in Shanghai in the last decade. While Barcelona's urban green space and green space per capita began declining between the 1950s and 1990s, they increased slightly over the past two decades. Shanghai, however, has consistently and significantly improved urban green space and green space per capita over the past six decades, especially since the economic reform in 1978. Economic development has a direct and significant influence on urban green space for both cities and post-industrialization had served as the main driving force for urban landscape change in Barcelona and Shanghai. Based on secondary statistical and qualitative data from on-site observations and interviews with local experts, we highlighted the institution's role in NBS planning. Furthermore, aspiration to become a global or globalizing city motivated both cities to use NBS planning as a place-making tool to attract global investment, which is reflected in various governing policies and regulations. The cities' effort to achieve a

    Background: 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. Objectives: We estimated associations between congenital anomalies and exposure to traffic-related air pollution in Barcelona, Spain. Method: 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. Results: 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. Conclusions: 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

    Heart failure (HF) diagnosis as reported in primary care medical records is not always properly confirmed and could result in over-registration. To determine the proportion of registered HF that can be confirmed with information from primary care medical records and to analyse related factors. 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. 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). 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.

    Occupational musculoskeletal disorders in the upper limbs and its consequences on the impact and prevalence in the work force are subject of many investigations in almost all the production fields. However, the exposure to this kind of risk factor on urban gardeners has not been well studied so far. The kind of plant varieties used in the parks, the tools that they use, as much as the necessary actions for the maintenance of the park, have an impact on the biomechanical overload of the upper limbs. Additionally, the analysis of the exposure to the biomechanical overload on upper limbs in gardening work is a complex task, mainly because it is an activity highly variable and of annual cycle. For this reason an analytical model for risk exposure evaluation is necessary. During this research the work activity of 29 gardeners in 3 urban parks of Barcelona has been analyzed. Each park has a specific acting plan, in relation with the quantity and the typology of vegetal species, its classification and the season of the year. Work and observation and video recording sessions on-site were conducted. The video-graphic registration was done on workers without any prior musculoskeletal disorder and with a minimum labour experience of 5 years. Moreover, the analysis of saturation time, considered as the relation of the repetitive working hours in reference with the hours of effective work was done. Using the registered tasks on video, the biomechanical overload on upper limbs applying the OCRA Checklist method was analyzed. A methodological procedure to analyze the risk exposure in annual working cycle has been proposed. The results that we got allow us to get information that can help in the assignment of the tasks and in the training of staff, as well as in the recommendations of the urban landscape's design. All these aspects have the goal to decrease the risk to develop work-related musculoskeletal disorders.

    2011-01-01

    Background Increasing international travel and migration is producing changes in trends in infectious diseases, especially in children from many European cities. The objective of this study was to describe the epidemiology and determine the trends of imported malaria in patients under 20 years old in the city of Barcelona, Spain, during an 18-year period. Methods The study included malaria cases that were laboratory confirmed and reported to the malaria register at the Public Health Agency of Barcelona from 1990 to 2008, residing in Barcelona and less than 20 years old. Patients were classified as natives (born in Spain) or immigrants. Differences in the distribution of demographic, clinical characteristics, and incidence per 100,000 person-year evolution were analysed. Natives and immigrants were compared by logistic regression by calculating the odds ratio (OR) with a 95% confidence interval (CI) and Chi-square for a linear trend (p < 0.05). Results Of the total 174 cases, 143 (82.1%) were immigrants, 100 (57.5%) were female, 121 (69.5%) Plasmodium falciparum, and 108 (62.1%) were visiting friends and relatives (VFR) as the reason for travel. Among the immigrants, 99 (67.8%) were from Equatorial Guinea. Immigrant cases more frequently travelled to Africa than natives (p = 0.02). The factors associated with imported malaria among immigrant residents was travelling for VFR (OR: 6.2 CI 1.9-20.2) and age 15-19 (OR: 3.7 CI 1-13.3). The incidence increased from 1990 to 1999 (p < 0.001) and decreased from 2000 to 2008 (p = 0.01), although the global linear trend was not statistically significant (p = 0.41). The fatality rate was 0.5%. Conclusions The majority of cases of malaria in population less than 20 years in Barcelona were immigrants, travelling to Africa for VFR and Plasmodium falciparum was most frequently detected. The trend analysis of the entire study period did not show a statistically significant decline. It is recommended to be aware of malaria, especially

    To monitor the amount of unused drugs and the cost to the public health system. Setting A random sample of community pharmacies in Barcelona, Spain. Method The drugs were collected from 38 community pharmacies over a period of 7 consecutive working days (excluding Sundays). A questionnaire was designed to evaluate each returned medicine. The resulting data were analyzed and evaluated. The number of drugs collected at the pharmacy, the characteristics of the clients and the reasons why they returned the drugs, and finally the economic value of the drugs returned and the cost to the public health system. A total of 227 clients (54.6% women, 64 +/- 20 years-old) returned 1,176 packages to the pharmacy. The number of packages collected in one return ranged from 1 to 121. The number of packages collected per pharmacy ranged from 0 to 188. In more than half of the cases (52.4%) the patients returned their drug in person and in 32.2% of the cases a relative returned it on their behalf. The main reason (28.2%) why drugs were returned was the expiry date. In 24.9% of the cases the patient's condition had improved and there was no further need for the drug. In 20.8% the patient had died. The estimated total cost of the collected drugs was euro8,539.9. Over 75% of this amount (euro6,463.9) had been paid by the public health system. This study confirms the importance of analyzing the return of unwanted medicines to reduce unnecessary health expenditure. It also highlights the inadequacies of the Spanish health system in the areas of prescription, dispensing and use of medicines. Establishing strategies to reduce the wastage of unused medicines is necessary.

    OBJECTIVE—This study describes social class inequalities in health related behaviours (tobacco and alcohol consumption, physical activity) among a sample of general population over 14 years old in Barcelona.
DESIGN—Cross sectional study (Barcelona Health Interview Survey).
SETTING—Barcelona city (Spain).
PARTICIPANTS—A representative stratified sample of the non-institutionalised population resident in Barcelona was obtained. This study refers to the 4171 respondents aged over 14.
DATA—Social class was obtained from a Spanish adaptation of the British Registrar General classification. In addition, sociodemographic variables such as family structure and employment status were used. As health related behaviours tobacco consumption, alcohol consumption, usual physical activity and leisure time physical activity were analysed. Age adjusted percentages were compared by social class. Multivariate analysis was performed using logistic regression models.
MAIN RESULTS—Women in the upper social classes were more likely to smoke, the adjusted odds ratio (OR) for social class V in reference to social class I was 0.36 (95% confidence intervals (95%CI): 0.19, 0.67), while the opposite occurred among men although it was not statistically significant in multivariate analysis. Smoking cessation was more likely among men in the higher classes (OR for class V 0.41, 95%CI: 0.18, 0.90). Excessive alcohol consumption among men showed no differences between classes, while among women it was greater in the upper classes. Engaging in usual physical activity classified as "light or none" in men decreased with lowering social class (OR class IVa: 0.55 and OR class IVb: 0.47). Women of social classes IV and V were less likely to have two or more health risk behaviours (OR for class V 0.33, 95% CI: 0.18, 0.62).
CONCLUSION—Health damaging behaviours are differentially distributed among social classes in Barcelona. Health policies should take into account these

    Myopia is one of the major causes of low visual acuity during childhood, and hence of the need for spectacles. It is generally more prevalent in urban areas where children are often less exposed to green spaces than in rural areas. This study evaluated the association between exposure to green space and use of spectacles (as a surrogate measure for myopia) in a cohort of 2727 schoolchildren (7-10 years old) recruited from 39 primary schools in Barcelona (2012-2015). We assessed exposure to green spaces by characterizing outdoor surrounding greenness at home and school and during commuting using satellite data on greenness (Normalized Difference Vegetation Index). We also obtained data on the annual average time children spent playing in green spaces through questionnaires. Cross-sectional analyses were conducted based on prevalent cases of spectacles use at baseline data collection campaign and longitudinal analyses based on incident cases of spectacles use during the three-year period between the baseline and last data collection campaigns. An interquartile range (IQR) increase in exposure to green space at home (500m buffer) and school and during commuting was associated with respectively 14% (95% CI: 2%, 26%), 27% (95% CI: 6%, 44%), and 20% (95% CI: 5%, 33%) decrease in spectacles use in cross-sectional analyses. In longitudinal analyses, we observed a reduction of 23% (95% CI: 4%, 39%) and 34% (95% CI: 2%, 55%) associated with an IQR increase in greenness at home and school, respectively. Moreover, an IQR increase in time playing in green spaces was associated with a 28% (95% CI: 7%, 45%) reduction in the risk of spectacles use in the longitudinal analysis. Our observed reduced risk of spectacles use associated with higher contact with green space calls for more refined studies of the association between green spaces and refractive errors of visions.

    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.

    The Barcelona continental shelf, off the city of Barcelona (NE Spain), is a relatively narrow canyon-bounded shelf in the northwestern Mediterranean Sea. Three medium-size rivers (Tordera, Besós and Llobregat) and several ephemeral rivulets flow into this margin. Two main domains have been recognized in the Barcelona shelf: (i) a modern, river-influenced area, and (ii) a relict, sediment depleted area, both affected by a variety of human impacts. A detailed geomorphologic study based on multibeam bathymetry and backscatter data, high resolution seismic profiles, and surface sediment samples allowed mapping and interpreting the main distinctive seafloor features on the Barcelona shelf. Modern sedimentary features reveal that the Llobregat River is the main sediment source of the Barcelona prodeltaic shelf. High-discharge fluvial events result in the formation of suspended sediment plumes and sediment waves on the shelf floor. Relict (late Pleistocene-Holocene) sedimentary features reflect that an important shift occurred in the seashore direction between MIS 4 and MIS 2, and that recent neotectonic reactivation has created a set of seafloor faults. The Barcelona inner and middle shelf is severely impacted by anthropogenic activities such as the enlargement works of the Port of Barcelona, sewage pipes, dredging, anchoring and trawling.

    The aim of this study was to analyze the factors associated with conventional contact tracing (CCT) and molecular epidemiology (ME) methods in assessing tuberculosis (TB) transmission, comparing the populations studied and the epidemiological links established by both methods. Data were obtained from TB case and CCT registries, and ME was performed using IS6110-based restriction fragment length polymorphism (RFLP) analysis and mycobacterial interspersed repetitive unit 12 (MIRU12) typing as a secondary typing method. During two years (2003 and 2004), 892 cases of TB were reported, of which 687 (77%) were confirmed by culture. RFLP analysis was performed with 463 (67.4%) of the 687 isolated strains, and MIRU12 types in 75 strains were evaluated; 280 strains (60.5%) had a unique RFLP pattern, and 183 (39.5%) shared patterns, grouping into 65 clusters. CCT of 613 (68.7%) of 892 cases detected 44 clusters involving 101 patients. The results of both CCT and ME methods yielded 96 clusters involving 255 patients. The household link was the one most frequently identified by CCT (corresponding to 80.7% of the cases clustered by this method), whereas nonhousehold and unknown links were associated with 94.1% of the strains clustered by ME. When both methods were used in 351 cases (39.3%), they showed the same results in 214 cases (61%). Of the remainder, 106 (30.2%) were clustered only by ME, 19 (5.5%) were clustered only by CCT, and 12 (3.4%) were clustered by both methods but into different clusters. Patients with factors potentially associated with social problems were less frequently studied by CCT (P = 0.002), whereas patients of <15 years of age, most with negative cultures, were less frequently studied by ME (P = 0.005). Significant differences in the populations studied by ME versus CCT were observed, possibly explaining the scarce correlation found between the results of these methods. Moreover, ME allowed the detection of nonhousehold contact relationships, whereas

    Workplace violence is a real phenomenon at nursing homes. This article studied this phenomenon in Barcelona. The objective of this study was to determine whether type II workplace violence takes place in senior citizen residences in Barcelona. To conduct this exploratory, descriptive and transversal study, the ad hoc QViLab II Questionnaire (version 1) was administered to professionals at senior citizen residences in Barcelona. The sample system used was the randomly stratified conglomerate system, using the size of the residence as the stratum to ensure the representativeness of the sample. Sixty-seven professionals from residences in Barcelona participated in the study. The results show that 61.2% (IC 95%: 58-65%) of the professionals believed that they have been assaulted by the residents they cared for in the previous year. With regard to the participant variables, we noticed a significant relationship between stress and the belief of having been assaulted. The professionals stated that male residents assaulted them more than females and that verbal aggression was the most common form of aggression from both males and females, followed by physical aggression. With regard to frequency, verbal demands were the kind most often expressed on a daily basis. Professionals from nursing homes in Barcelona perceived workplace violence.

    A retrospective, space-time study of whooping cough cases reported to the Public Health Agency of Barcelona, Spain between the years 2000 and 2011 is presented. It is based on 633 individual whooping cough cases and the 2006 population census from the Spanish National Statistics Institute, stratified by age and sex at the census tract level. Cluster identification was attempted using space-time scan statistic assuming a Poisson distribution and restricting temporal extent to 7 days and spatial distance to 500 m. Statistical calculations were performed with Stata 11 and SatScan and mapping was performed with ArcGis 10.0. Only clusters showing statistical significance (P <0.05) were mapped. The most likely cluster identified included five census tracts located in three neighbourhoods in central Barcelona during the week from 17 to 23 August 2011. This cluster included five cases compared with the expected level of 0.0021 (relative risk = 2436, P <0.001). In addition, 11 secondary significant space-time clusters were detected with secondary clusters occurring at different times and localizations. Spatial statistics is felt to be useful by complementing epidemiological surveillance systems through visualizing excess in the number of cases in space and time and thus increase the possibility of identifying outbreaks not reported by the surveillance system.

    This article describes case study research for nursing and healthcare practice. Case study research offers the researcher an approach by which a phenomenon can be investigated from multiple perspectives within a bounded context, allowing the researcher to provide a 'thick' description of the phenomenon. Although case study research is a flexible approach for the investigation of complex nursing and healthcare issues, it has methodological challenges, often associated with the multiple methods used in individual studies. These are explored through examples of case study research carried out in practice and education settings. An overview of what constitutes 'good' case study research is proposed.

    The aim of this research project was to carry out an epidemiological study on the voice health of the teaching population in Granollers (Barcelona) using the EVES questionnaire and to relate the collected data to the VHI results. The study sample consisted of 233 teachers from Granollers (Barcelona). The EVES questionnaire, which includes the VHI-10, was conducted online. A high percentage of the teachers consulted suffered voice disorders, which ranged from minor to more serious cases. In regard to the data obtained using the VHI, in 28.77% of the cases there was a moderate or a serious perception of voice problems. Out of these cases only one person, who had a moderate perception of their problem, was undergoing voice therapy with a speech therapist. There are three questions in the EVES questionnaire that can efficiently indicate the existence of a voice disorder in a straightforward manner, and the results for these were similar to those recorded for the VHI group of questions. Therefore, it may be argued that questions that refer to the perception of the degree of pleasantness of one's own voice should be included, because they would provide a useful way to indicate whether there is a voice problem at a preliminary screening stage.

    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

    The objective of this study was to examine the relationship between educational level and mortality from cancer in the city of Barcelona. The data were derived from a record linkage between the Barcelona Mortality Registry and the Municipal Census. The relative risks (RR) of death and 95% confidence intervals (CIs) according to level of education were derived from Poisson regression models. For all malignancies, men in the lowest educational level had a RR of death of 1.21 (95% CI 1.13–1.29) compared with men with a university degree, whereas for women a significant decreasing in risk was observed (RR 0.81; 95% CI 0.74–0.90). Among men, significant negative trends of increasing risk according to level of education were present for cancer of the mouth and pharynx (RR 1.70 for lowest vs. highest level of education), oesophagus (RR 2.14), stomach (RR 1.99), larynx (RR 2.56) and lung (RR 1.35). Among women, cervical cancer was negatively related to education (RR 2.62), whereas a positive trend was present for cancers of the colon (RR 0.76), pancreas (RR 0.59), lung (RR 0.55) and breast (RR 0.65). The present study confirms for the first time, at an individual level, the existence of socioeconomic differences in mortality for several cancer sites in Barcelona, Spain. There is a need to implement health programmes and public health policies to reduce these inequities. © 1999 Cancer Research Campaign PMID:10027350

    This study is composed of 517 adult voluntary participants, from Barcelona and its surroundings, all of whom are from Spain, Barcelona, and Catalonia. The study builds on a previously published report for a smaller sample (N = 250; see Alvarez, Baeza, Campo, Garcia, Guardia, et al., 1993) and is the result of collaboration between students and professors at the Barcelona Rorschach School (Catalan Rorschach Society). Our aim is to offer local data that should help to understand possible differences with existing reference data for the Rorschach Comprehensive System (CS; Exner, 2005), which is the system that has been taught at this school since 1978. Inclusion and exclusion criteria are described and interrater reliability statistics at the response level are presented, along with scores for the CS, followed by a discussion and very brief comparison with other international reference samples.

    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.

    Case studies and case reports form an important and ever growing part of scientific and scholarly literature. The paper deals with the share and citation rate of these publication types on different fields of research. In general, evidence seems to support the opinion that an excessive number of such publications may negatively influence the impact factor of the journal. In the literature of scientometrics, case studies (at least the presence of the term "case study" in the titles of the papers) have a moderate share, but their citation rate is practically equal to that of other publication types.

    Background Community-acquired pneumonia (CAP) has large impact on direct healthcare costs, especially those derived from hospitalization. This study determines impact, clinical characteristics, outcome and economic consequences of CAP in the adult (≥18 years) population attended in 6 primary-care centers and 2 hospitals in Badalona (Spain) over a two-year period. Methods Medical records were identified by codes from the International Classification of Diseases in databases (January 1st 2008-December 31st 2009). Results A total of 581 patients with CAP (55.6% males, mean age 57.5 years) were identified. Prevalence: 0.64% (95% CI: 0.5%-0.7%); annual incidence: 3.0 cases/1,000 inhabitants (95% CI: 0.2-0.5). Up to 241 (41.5%) required hospitalization. Hospital admission was associated (p<0.002) with liver disease (OR=5.9), stroke (OR=3.6), dementia (OR=3.5), COPD (OR=2.9), diabetes mellitus (OR=1.9) and age (OR=1.1 per year). Length of stay (4.4±0.3 days) was associated with PSI score (β=0.195), in turn associated with age (r=0.827) and Charlson index (r=0.497). Microbiological tests were performed in all inpatients but only in 35% outpatients. Among patients with microbiological tests, results were positive in 51.7%, and among them, S pneumoniae was identified in 57.5% cases. Time to recovery was 29.9±17.2 days. Up to 7.5% inpatients presented complications, 0.8% required ICU admission and 19.1% readmission. Inhospital mortality rate was 2.5%. Adjusted mean total cost was €2,332.4/inpatient and €698.6/outpatient (p<0.001). Patients with pneumococcal CAP (n=107) showed higher comorbidity and hospitalization (76.6%), higher PSI score, larger time to recovery and higher overall costs among inpatients. Conclusions Strategies preventing CAP, thus reducing hospital admissions could likely produce substantial costs savings in addition to the reduction of CAP burden. PMID:23114195

    2003-03-01

    Numerical simulations with photochemical transport models were independently performed for two domains situated in the Iberian Peninsula covering the Lisbon and Barcelona airsheds. Although the days chosen for simulation of the two cities are not the same, the synoptic situations in both cases, known as typical summertime situations, were similar, which allowed the development of typical mesoscale circulations, such as sea breezes and mountain and valley winds dominated by the Azores anticyclone. Emission inventories for the two areas were developed. The O3 concentrations recorded in both cities have a similar level. Nevertheless, O(x) values in Barcelona are higher than in Lisbon, which may, at a first glance, indicate an apparently more oxidant atmosphere in Barcelona. Photochemical modeling for the two cities has shown that the behavior of the circulatory patterns in both urban areas is rather different, which mainly has to do with the different strengths of the sea breeze and the topography, inducing an important offshore vertical layered dimension of pollutant transport in Barcelona versus an important inland horizontal transport in Lisbon.

    The immigrant population (IP) is visiting neurology departments on an increasingly more frequent basis. Research has still not made it clear whether there are geographical differences in the prevalence of primary headaches and the possible influence of emigration. We conducted a retrospective (12 months) and prospective study (18 months) of the first visits to the Headache Unit at the Hospital de la Santa Creu i Sant Pau. Data collected included the country of birth, time parameters of the headache and of the immigration, diagnoses according to the criteria of the IHS and treatments that had been used. Related headaches were considered to be those that began within one year of having immigrated. The IP represents 13.6% (n = 142) of the total number of first visits because of headaches (n = 1044). Immigrants came mostly from Latin America (83.9%). Headaches began after immigration in 40.1% of cases without the existence of any temporal relation with immigration. The distribution of the diagnoses of headache is similar to those of the local population, the most frequent being migraine (57.7%) and tension-type headache (15.5%). On comparing treatments prior to and following immigration, we find differences in the use of triptans (2.1% versus 46.2%), ergotamine (9.8% versus 2.1%) and in the use of preventive treatments (2% versus 45%). The IP accounts for 13% of all first visits due to headaches and their diagnoses are similar to those of the local population. Emigration is neither a precipitating nor an aggravating factor for headaches in our series. There is a significant difference in symptomatic and preventive treatment between the period prior to immigration and afterwards.

    A study was conducted to determine the baseline of total contents (XRF) of Ba, Cu, Ga, Ni, Pb, Rb, Sn, Sr, V, and Zn in soils from the Tarragona and Barcelona coastal area and Central Uplands of Barcelona, Catalonia, NE Spain, and to establish relationships between heavy metals and some soil properties. A total of 94 samples (47 soil plots) were collected from topsoils and subsurface soils in the main soil types. The median concentrations (mg kg-1) obtained were Ba 412 (range 113-954 mg kg-1), Cu 19.4 (5-91 mg kg-1), Ga 12.5 (5-21.7 mg kg-1 ), Ni 24 (7-56.5 mg kg-1 ), Pb 25 (9-100 mg kg-1), Rb 79 (34-140 mg kg-1 ), Sn 2 (1-8 mg kg-1 ), Sr 102 (43-401 mg kg-1 ), V 68.5 (22-170 mg kg-1 ), and Zn 66 (20-137 mg kg-1 ). The concentrations of trace elements in Catalonia were similar to those given by other authors from different countries of the Mediterranean regions. In terms of soil properties, the results of this study suggest that in these soils trace elements adsorption and retention are influenced by several properties such as clay minerals and pH. Almost all element concentrations were positively correlated with clay content and negatively correlated with carbonates. The very strong positive correlations between V, Ni, V, and Ga point to their natural origin.

    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.

    Hourly measurements of pollen near-surface concentration and lidar-derived profiles of volume and particle depolarization ratios during a 5-day pollination event observed in Barcelona, Spain, between 27 - 31 March, 2015, are presented. Maximum hourly pollen concentrations of 4700 and 1200 m-3 h-1 were found for Platanus and Pinus, respectively, which represented together more than 80 % of the total pollen. . The pollen concentration was found positively correlated with temperature (correlation coefficient, r, of 0.95) and wind speed (r = 0.82) and negatively correlated with relative humidity (r = -0.18). The ground concentration shows a clear diurnal cycle although pollen activity is also detected during nighttime in three occasions and is clearly associated with periods of strong wind speeds. Everyday a clear diurnal cycle caused by the vertical transport of the airborne pollen was visible on the lidar-derived profiles of the volume depolarization ratio with maxima usually reached between 12 and 15 UT. On average the volume depolarization ratios in the pollen plume ranged between 0.08 and 0.22. Except in the cases of nocturnal pollen activity, the correlation coefficients between volume depolarization ratio and near-surface concentration are high (>0.68). The dispersion of the Platanus and Pinus in the atmosphere was simulated with the Nonhydrostatic Multiscale Meteorological Model on the B grid at the Barcelona Supercomputing Center with a newly developed Chemical Transport Model (NMMB/BSC-CTM). Model near-surface daily pollen concentrations were compared to our observations at two sites: in Barcelona and Bellaterra (12 km NE of Barcelona). Model hourly pollen concentrations were compared to our observations in Barcelona. Better results are obtained for Pinus than for Platanus. Guidelines are proposed to improve the dispersion of airborne pollen by atmospheric models.

    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.

    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

    Cohort studies of large series of patients with sarcoidosis over a long period of time are scarce. The aim of this study is to report a 40-year clinical experience of a large series of patients at Bellvitge University Hospital, a tertiary university hospital in Barcelona, Spain. Diagnosis of sarcoidosis required histological confirmation except in certain specific situations. All patients underwent a prospective study protocol. Clinical assessment and follow-up of patients were performed by a multidisciplinary team.From 1976 to 2015, 640 patients were diagnosed with sarcoidosis, 438 of them (68.4%) were female (sex ratio F/M 2:1). The mean age at diagnosis was 43.3 ± 13.8 years (range, 14-86 years), and 613 patients (95.8%) were Caucasian. At diagnosis, 584 patients (91.2%) showed intrathoracic involvement at chest radiograph, and most of the patients had normal pulmonary function. Erythema nodosum (39.8%) and specific cutaneous lesions (20.8%) were the most frequent extrapulmonary manifestations, but there was a wide range of organ involvement. A total of 492 patients (76.8%) had positive histology. Follow-up was carried out in 587 patients (91.7%), over a mean of 112.4 ± 98.3 months (range, 6.4-475 months). Corticosteroid treatment was administered in 255 patients (43.4%), and steroid-sparing agents in 49 patients (7.7%). Outcomes were as follows: 111 patients (18.9%) showed active disease at the time of closing this study, 250 (42.6%) presented spontaneous remission, 61 (10.4%) had remission under treatment, and 165 (28.1%) evolved to chronic sarcoidosis; among them, 115 (19.6%) with mild disease and 50 (8.5%) with moderate to severe organ damage. A multivariate analysis showed that at diagnosis, age more than 40 years, the presence of pulmonary involvement on chest radiograph, splenic involvement, and the need of treatment, was associated with chronic sarcoidosis, whereas Löfgren syndrome and mediastinal lymphadenopathy on chest radiograph were

    In the Agrarian Engineering school of Barcelona, within the subject of Mathematics some references to history are included, particularly about several great scientists, like Kepler who is famous for his astronomical laws, but he was occupied by other subjects for example he wrote about wine barrels. It is interesting to introduce students to dynamic aspects of science and not only to program an ordered mathematical knowledge of physical systems or, worse, only to offer a collection of numerical recipes or only presenting the foundation of theory; it is important to promote relationships between technical topics and other lateral matters. To instigate an integral education, students did a brief study entitled "Kepler, mathematics and agriculture"; students were guided to link Kepler with agriculture through astronomy.

    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.

    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.

    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.

    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

The purpose of this study is to establish connections between BMS and the following variables: age, sex, overt depression, masked depression, cancerophobia, dry mouth, foreign body sensation in the mouth, and burning. 140 clinical cases of patients diagnosed with the disease and 140 cases of control patients are studied here. The data were statistically analyzed to study connections as well as the disease and variables frequency. The obtained results will help understanding possible connections of the studied etiologic and clinical factors with the disease, as well as the course of BMS, and its consequences in the Catalan population.

    To investigate the efficacy and safety of adjuvant sorafenib after curative resection for patients with Barcelona Clinic Liver Cancer (BCLC)-stage C hepatocellular carcinoma (HCC). Thirty-four HCC patients, classified as BCLC-stage C, received adjuvant sorafenib for high-risk of tumor recurrence after curative hepatectomy at a tertiary care university hospital. The study group was compared with a case-matched control group of 68 patients who received curative hepatectomy for HCC during the study period in a 1:2 ratio. The tumor recurrence rate was markedly lower in the sorafenib group (15/34, 44.1%) than in the control group (51/68, 75%, P = 0.002). The median disease-free survival was 12 mo in the study group and 10 mo in the control group. Tumor number more than 3, macrovascular invasion, hilar lymph nodes metastasis, and treatment with sorafenib were significant factors of disease-free survival by univariate analysis. Tumor number more than 3 and treatment with sorafenib were significant risk factors of disease-free survival by multivariate analysis in the Cox proportional hazards model. The disease-free survival and cumulative overall survival in the study group were significantly better than in the control group (P = 0.034 and 0.016, respectively). Our study verifies the potential benefit and safety of adjuvant sorafenib for both decreasing HCC recurrence and extending disease-free and overall survival rates for patients with BCLC-stage C HCC after curative resection.

    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.

    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

    Background Early diagnosis of HIV infection can prevent morbidity and mortality as well as reduce HIV transmission. The aim of the present study was to assess prevalence, describe trends and identify factors associated with late presentation of HIV infection in Barcelona (Spain) during the period 2001-09. Methods Demographic and epidemiological characteristics of cases reported to the Barcelona HIV surveillance system were analysed. Late presentation was defined for individuals with a CD4 count below 350 cells/ml upon HIV diagnosis or diagnosis of AIDS within 3 months of HIV diagnosis. Multivariate logistic regression were used to identify predictors of late presentation. Results Of the 2,938 newly diagnosed HIV-infected individuals, 2,507 (85,3%) had either a CD4 cell count or an AIDS diagnosis available. A total of 1,139 (55.6%) of the 2,507 studied cases over these nine years were late presenters varying from 48% among men who have sex with men to 70% among heterosexual men. The proportion of late presentation was 62.7% in 2001-2003, 51.9% in 2004-2005, 52.6% in 2006-2007 and 52.1% in 2008-2009. A decrease over time only was observed between 2001-2003 and 2004-2005 (p = 0.001) but remained constant thereafter (p = 0.9). Independent risk factors for late presentation were older age at diagnosis (p < 0.0001), use of injected drugs by men (p < 0.0001), being a heterosexual men (p < 0.0001), and being born in South America (p < 0.0001) or sub-Saharan Africa (p = 0.002). Conclusion Late presentation of HIV is still too frequent in all transmission groups in spite of a strong commitment with HIV prevention in our city. It is necessary to develop interventions that increase HIV testing and facilitate earlier entry into HIV care. PMID:21729332

    Introduction and Objectives: The central odontogenic fibroma (COF) is a benign odontogenic tumour derived from the dental mesenchymal tissues. It is a rare tumour and only 70 cases of it have been published. Bearing in mind the rareness of the tumour, 8 new cases of central odontogenic fibroma have been found by analyzing the clinical, radiological and histopathological characteristics of COF. Patients and Method: A retrospective study was carried out on 3011 biopsies in the Service of Oral and Maxillofacial Surgery of the Dental Clinic of Barcelona University between January 1995 and March 2008. 85 odontogenic tumours were diagnosed of which 8 were central odontogenic fibroma. The radiological study was based on orthopantomographs, periapical and occlusal radiographies and computerised tomographics. The variables collected were: sex, age, clinical characteristics of the lesion, treatment received and possible reappearances of the tumour. Results: The central odontogenic fibroma represents 9.4% of all odontogenic tumours. Of the 8 cases, 5 were diagnosed in men and 3 in women. The average age was 19.9 years with an age range of 11 to 38 years. The most common location of the tumour was in the mandible. All cases were associated with unerupted teeth. Of the 8 tumours, 3 provoked rhizolysis of the adjacent teeth and 4 cases caused cortical bone expansion. 50% of the patients complained of pain associated to the lesion. No case of recurrence was recorded up to 2 years after the treatment. Conclusions: Central odontogenic fibromas usually evolve asymptomatically although they can manifest very aggressively provoking dental displacement and rhizolysis. Radiologically, COF manifest as a uni or multilocular radiotransparent image although they can be indistinguishable from other radiotransparent lesions making diagnosis more difficult. COF treatment involves conservative surgery as well as follow-up patient checks. Key words: Odontogenic tumour, central odontogenic

  7. Emissions variation in urban areas resulting from the introduction of natural gas vehicles: application to Barcelona and Madrid greater areas (Spain).

    On-road traffic is the major contributor to pollutant emissions in urban areas. Nowadays different emission abatement strategies are being tested in order to improve urban air quality (e.g. the European Commission currently promotes the use of natural gas as an alternative fuel). Several feasible scenarios regarding the introduction of natural gas vehicles (NGV) are studied in the two main cities of Spain (Barcelona and Madrid) by using the HERMES emission model. The most suitable emission factors to NGV are selected among those available in the literature. The account of emissions in the base case scenario estimated for a typical summertime polluted day of the year 2004 reflects that in Barcelona 86% of primary pollutants come from on-road traffic compared to 93% in Madrid, because of the heavier industrial activity in the former. The introduction of NGV in urban zones would have a positive effect on emissions, whose extent largely depends on the substituted fleets and the conurbation characteristics. Maximum reductions in NO(x) emissions in Madrid are attributed to the substitution of 10% of the oldest diesel and petrol cars, while in Barcelona the change of 50% of the oldest commercial light vehicles becomes more effective. PM(2.5) and SO(2) emissions can be significatively reduced with the introduction of NGV instead of the oldest commercial light vehicles. The substitution of conventional fuels by natural gas must reach around 4% to achieve significative reductions in traffic emissions (larger than 5%). This work focuses on air quality issues, therefore GHG emissions are not included, nevertheless this kind of associated impact has to be considered by the decision makers. Assessing the efficacy of environmental improvement strategies entails a realistic design of emission scenarios and their evaluation. The detailed emission account provides a fundamental basis for the air quality modelling and its comparison among scenarios.

  8. Emission inventory for greenhouse gases in the City of Barcelona, 1987-1996

    NASA Astrophysics Data System (ADS)

    Baldasano, José M.; Soriano, Cecilia; Boada, Lluís.

    Emissions of greenhouse gases for the City of Barcelona are estimated for the period 1987-1994. The sources considered are: public and private transportation; industrial, commercial and domestic activities; and municipal solid waste disposal. The results show that the main source of CO 2 emissions in Barcelona is private vehicle transportation, which accounts, as an average for the period studied, for 35% of total emissions. The second most important source is the municipal solid waste landfill facility of the city (24% of total emissions). The percentages for the remaining sources under consideration were: 14% electricity, 12% natural gas, 5% incineration, and 3% liquefied petroleum gases. However, the values for CO 2 emissions per inhabitant over the period studied are lower than those for any other industrialized city available for comparison. This is closely related to the high percentage of electricity generation from nuclear power stations and hydro power facilities, and also to the extensive use of natural gas for domestic uses.

    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.

    Delphi Automotive Systems and the Los Alamos National Laboratory worked together to develop PREDICT, a new methodology to characterize the reliability of a new product during its development program. Rather than conducting testing after hardware has been built, and developing statistical confidence bands around the results, this updating approach starts with an early reliability estimate characterized by large uncertainty, and then proceeds to reduce the uncertainty by folding in fresh information in a Bayesian framework. A considerable amount of knowledge is available at the beginning of a program in the form of expert judgment which helps to provide the initial estimate. This estimate is then continually updated as substantial and varied information becomes available during the course of the development program. This paper presents a case study of the application of PREDICT, with the objective of further describing the methodology. PREDICT has been honored with an R&D 100 Award presented by R&D Magazine.

    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.

    To describe and compare breast and cervical cancer screening among women in Barcelona in 1992, 2001, and 2006 by social class, age, and screening approach. This was a study of trends based on analysis of Barcelona health interview surveys for the years 1992 (n=5,003), 2001 (n=10,030), and 2006 (n=6,050). Dependent variables were having regular mammographies (at least every 2 years) and having regular cytologic testing (at least every 3 years). Independent variables were age, social class, and survey year. A descriptive analysis was carried out. To compare prevalence in terms of social class and the years studied, we calculated prevalence differences (PD) and prevalence ratios (PR) by fitting robust Poisson regression models. In 1992, women aged 40?49 had more regular mammographies than those aged 50?69, with social class inequalities in both age groups. Having cervical cancer screening was more common than having breast cancer screening, with prevalence varying from 46.4% in the low social classes to 59.2% in the high classes. In 2001, breast cancer screening had risen, particularly in women aged 50?69, a tendency that had stabilized by 2006. Inequalities diminished over the period, more markedly in women aged 50?69; PRs of 1.22 and 1.58, respectively, for high and middle social classes with respect to the lowest class in 1992 fell to PRs of 1.07 and 1.08, respectively, in 2006. In the case of cervical cancer screening, inequalities also diminished but not to the same extent. Preventive screening for breast and cervical cancer has increased, and the population screening program for breast cancer among women aged 50?69 years appears to contribute more than opportunistic screening for cervical cancer in reducing social class inequalities.

    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.

    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.

    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.

    In this article I posit and examine certain criteria and qualities for ending an analysis. The case study describes the end phase of a four-year psychoanalysis in which the patient's decision to move to another area forced the end of his analysis. We continued to explore and work through his core neurotic conflicts that included issues of competitive rivalry, dominance and submission, control, and anxiety about birth and death. A shift in the transference from me as a negative father to me as a supportive but competitive older brother was also examined in the context of ending treatment as well as other aspects of the transference. In addition, we analyzed the meaning of his ending treatment based on an extra-analytic circumstance. In discussing this phase of treatment, the definition and history of the term "termination" and its connotations are reviewed. Various criteria for completing an analysis are examined, and technical observations about this phase of treatment are investigated. It was found that while a significant shift in the transference occurred in this phase of the patient's analysis, conflicts related to the transference were not "resolved" in the classical sense. Terminating treatment was considered as a practical matter in which the patient's autonomy and sense of choice were respected and analyzed.

    The need to notify individuals of a possible health risk from their past exposure to potentially hazardous agents frequently extends beyond workers to include community groups. The issues to consider in community notification are frequently similar to those that are important for worker notification but may include some that are unique. This case study traces the evolution of one company's strategy for communicating with the public about possible dioxin contamination associated with its operations. Early communications tended to emphasize the technical aspects of the issues in the fashion of scientists talking to other scientists. This was interpreted by some to be symptomatic of an arrogant and uncaring attitude. Beginning in the early 1980s, the company's management recognized the need to reach out to a variety of audiences on multiple levels, and shifted to a more comprehensive communications strategy. A similar shift is now occurring throughout the chemical manufacturing industry as top managers realize that, if they expect to continue to operate, they must become more accountable and responsive to the public.

    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.

    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.

    A few empirically based studies' data on delusional disorder (DD) exist. We aim to describe sociodemographic and clinical correlates of DD and to identify clinical profiles associated to DD and its subtypes. This is a case-register study based on all those subjects attending community mental health services within a geographically well-defined area. Four hundred and sixty-seven patients had been diagnosed as DD cases at psychiatric services serving a catchment area of some 607,494 inhabitants living in South Barcelona (Spain) during a three-year period (2001-2003). A thorough systematic review of computerised medical records was used to establish DSM-IV diagnosis, rendering a valid sample of 370 patients who fulfilled DSM-IV criteria for DD. Independent variables gathered include sociodemographic data, family and personal psychiatric history, and comorbid diagnoses on all DSM-IV axes (including GAF). We used descriptive and univariate statistical methods to explore sample frequencies and correlates across DD types. The mean age of the patients was 55 years and the sample had a mean GAF score of 51 suggesting a poor functionality; 56.5% of the patients were female. The most frequent DD types were persecutory (48%), jealous (11%), mixed (11%) and somatic (5%), whilst 23% qualified for the NOS type. Most frequent symptoms identified were self-reference (40%), irritability (30%), depressive mood (20%) and aggressiveness (15%). Hallucinations were present in 16% of the patients (6% tactile; 4% olfactory). Nearly 9% had a family history of schizophrenia (higher among those with the jealous subtype) and 42% had a comorbid axis II diagnosis (mostly paranoid personality disorder). Depression was significantly more frequent among the persecutory and jealous types. Finally, global functioning was significantly better among jealous and mixed types and worse amongst erotomanic and grandiose cases (p=0.008). In the absence of other similar empirical data, this modest study

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.

    Fulminant hepatic failure (FHF), also known as fulminant hepatitis, is a rare and extremely serious condition with a high mortality rate. Its rapid evolution and complexity in managing the treatment, creates the need to provide some immediate care by a team that specialises in intensive care. This acute decompensation is usually associated with other disorders, such as coagulopathy and hepatic encephalopathy, being responsible for major complications that can lead to organ failure. In our region the most common origin is unknown, followed by acute infection with hepatitis B. The treatment of this syndrome is based on the general measures applicable to any critically ill patient: treat the cause and early detection of extrahepatic complications, urgent liver transplantation being one of the alternatives with a better prognosis. This article presents a case report describing the monitoring of an Irish woman of 20 years who was transferred from a hospital in Ibiza to a hospital in Barcelona, with a suspected diagnosis of FHF. Following the conceptual model of Virginia Henderson, the collaborative problems and nursing diagnoses are described, presenting a care plan according to NANDA (North American Nursing Association), NIC (Nursing Intervention Classification), NOC (Nursing Outcomes Classification). This case helps to establish an individualised care plan that provides guidance to nurse professionals in critical patient care by increasing the knowledge of FHF.

    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.

    Immigration from socioeconomically under-developed countries is relatively recent in our country. Analyzing the impact of diseases such as HIV/AIDS and tuberculosis among these populations is of particular interest with regard to public health. Case study and tests conducted at the Male Prison Facility in Barcelona from January 1, 1996 to September 30, 1996, the cases being the foreign immigrants from socioeconomically underdeveloped countries, and the checks of the native prisoners paired by age (+/- 5 years). A description is provided of the epidemiological and sociodemographic characteristics of the immigrants, and a comparison is drawn between the two populations. 450 prisoners, 300 native and 150 immigrants. Sixty-three percent (63%) of the immigrants were from the Maghreb, 72% being in this country illegally, 55% having resided in our country for over 5 years and 53% not living with any family members. The immigrants used less injected drugs that the native prisoners (OR: 0.2; IC95% 0.09-0.41), had less HIV infection (OR: 0.2; IC95% 0.05-0.49) and lived to a lesser extent with family (OR: 0.2; IC95% 1.011-0.36). No differences were found to exist with regard to infection by Mycobacterium tuberculosis nor tubercular disease. The legal immigrants were older (OR: 1.07; IC95% 1.01-1.13) lived to a greater extent with family (OR: 2.7; IC95% 1.23-5.80) and drank more alcohol (OR: 1.7; IC95% 1.07-2.59) than the illegal residents. The native prisoners had HIV to a greater extent than the immigrants, the use of injected drugs, more common among the natives, bearing an influence on this aspect. As regards the immigrants, the high degree of illegal residence and the absence of a stable core family comprise indicators of a situation of being socially disadvantaged.

    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

    2012-01-01

    Background The important increase in immigration during recent years has changed the epidemiology and control strategies for tuberculosis (TB) in many places. This study evaluates the effectiveness of intervention with community health workers (CHW) to improve contact tracing among immigrants. Methods The study included all TB cases detected by the Barcelona TB Program from 2000 to 2005 and compared a period without CHW intervention (2000-2002) to a period with CHW intervention (2003-2005). The influence on contact tracing of sex, age, hospital of diagnosis, district of residence, birthplace, HIV, homeless and CHW intervention was analysed by logistic regression. Odds ratio (OR) and 95% confidence intervals (CI) were calculated. Results 960 foreign born TB cases were detected, 388 in the intervention period. Contact tracing was performed on 65,7% of 201 smear-positive cases during the pre-intervention period compared to 81.6% of 152 smear-positive TB cases during the intervention period (p < 0.001). Risk factors associated with incomplete contact tracing of smear-positive index cases included being diagnosed in two hospitals without contact tracing TB unit (OR = 3.5; CI:1.4-8.9) and (OR = 4.6; CI:1.6-13.5) respectively, birth place in India-Pakistan (OR = 4.4; CI:1.9-10.3) or North Africa (OR = 4.3; CI:1.8-10.5), having an unknown residence (OR = 5.4; CI:1.6-18.0), being HIV-infected (OR = 6.1; CI:2.5-14.8) or homeless (OR = 3.3; CI:1.3-8.2), and the absence of CHW intervention (OR = 2.4; CI:1.3-4.3). Conclusions The effectiveness of contact tracing for TB control in areas with high immigration can be improved by incorporating CHWs who act as translators, cultural mediators and facilitators who accompany cases and contacts through treatment and follow-up.

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

    To identify primary care teams (PCT) with the best overall performance and compare these with other PCT with benchmarking methods. Descriptive, cross-sectional study of a set of indictors for the year 2002. City of Barcelona (northeastern Spain). Thirteen seven PCT with more than 2 years' experience, and 771,811 inhabitants in the catchment area. Indicators were chosen from among those proposed by an advisory group, depending on feasibility of obtaining information. A total of 17 indicators in 4 dimensions were studied: accessibility, clinical effectiveness, case management capacity, and cost-efficiency. Each PCT was scored for each indicator based on the percentile group in the distribution of scores, and for each dimension based on the mean score for all indicators in a given dimension. Overall score for PCT performance was calculated as the weighted sum of the scores for each dimension. As descriptive variables we analyzed time operating under the revised administrative system, patient visits per population served, the population's economic capacity and age of the population. RESULTS. Nine PCT were identified as the benchmark group. Teams in this group had been operating under the revised administrative system for significantly longer than other PCT. In comparison to other PCT, the benchmark group obtained higher scores on all four dimensions, better results on 14 separate indicators, the same results for 1 indicator, and worse results for 2 indicators. CONCLUSIONS. Benchmarking made it possible to identify PCT with the best performance, and to identify areas in need of improvement. This approach is a potentially useful tool for self-evaluation and for stimulating a dynamic for improvement in primary care providers.

  8. 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.

    Everyone in science should have ethics education training. I have seen graduate students taken advantage of by their mentors. Many of us have seen misconduct...but what should we do about it? Young scientists are often unaware of the rules in science and make mistakes because of their ignorance of the rules in that particular field of study. Then there are an increasing number of cases in the news of overt cases of misrepresentation in science. All are welcome to attend this discussion of case studies. A case study on topics such as: how to treat data properly, how our values in science affect our work, who gets authorship on scientific papers, who is first author on a paper, what you should do if you uncover misconduct or plagiarism in your university, and we will discuss the scientist's role in society. This will be a painless, non-confrontational small group, then large group discussion of each case

    Background. The Barcelona Music Reward Questionnaire (BMRQ) questionnaire investigates the main facets of music experience that could explain the variance observed in how people experience reward associated with music. Currently, only English and Spanish versions of this questionnaire are available. The objective of this study is to validate a French version of the BMRQ. Methods. The original BMRQ was translated and adapted into an international French version. The questionnaire was then administered through an online survey aimed at adults aged over 18 years who were fluent in French. Statistical analyses were performed and compared to the original English and Spanish version for validation purposes. Results. A total of 1,027 participants completed the questionnaire. Most responses were obtained from France (89.4%). Analyses revealed that congruence values between the rotated loading matrix and the ideal loading matrix ranged between 0.88 and 0.96. Factor reliabilities of subscales (i.e., Musical Seeking, Emotion Evocation, Mood Regulation, Social Reward and Sensory-Motor) also ranged between 0.88 and 0.96. In addition, reliability of the overall factor score (i.e., Music reward) was 0.91. Finally, the internal consistency of the overall scale was 0.85. The factorial structure obtained in the French translation was similar to that of the original Spanish and English samples. Conclusion. The French version of the BMRQ appears valid and reliable. Potential applications of the BMRQ include its use as a valuable tool in music reward and emotion research, whether in healthy individuals or in patients suffering from a wide variety of cognitive, neurologic and auditory disorders.

    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.

    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.

    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.

    Breaking the students into small, collaborative learning groups to solve a meaningful task together is one of the most successful and fully evaluated teaching techniques implemented over the last century. Although there are many ways to accomplish small group learning, a long-standing and consistently successful collaborative class activity is to use the case study teaching strategy. The use of case studies is common in medical schools and law schools, but not so common in the teaching of astronomy. Case studies create meaningful conversations among students and with the professor by focusing on life-like dilemmas to be solved. Case study tasks ask audience members to synthesize several ideas or evaluate scenarios that have not been explicitly presented to them in the lecture or in available readings.

    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.

    The main purpose of this study was to analyse inequalities between tuberculosis/intravenous drug user and tuberculosis/not intravenous drug user among the different neighbourhoods of Barcelona and the relationship to socioeconomic indicators and social/material deprivation indicators throughout the 1990-1995 period. An ecological study which included all cases of tuberculosis among residents of Barcelona, the analysis unit being the neighbourhood. Intravenous drug users within the 15-49 age range and non-intravenous drug users over age 14 were included. The mean annual incidence rate standardized by age was used. The social indicators considered were the inner city areas, unemployment, less than primary education, overcrowding, social unrest and extreme poverty. In the bivariate analysis, the relationship between tuberculosis incidence and the social indicators was studied by means of the Spearman correlation coefficient, and the multivariate analysis by means of the Poisson regression. The incidence rates were higher in the inner city neighbourhoods, followed by the newer outlying working class neighbourhoods in both groups studied, and in other older outlying districts for the non-users of intravenous drugs. Among the intravenous drug user group, the variables related to a greater risk of tuberculosis were: man (RR = 7.42, confidence interval at 95% ICI95%-: 6.16-8.93), age (RR = 61.51, CI95%: 34.64-109.20), unemployment (RR = 1.68, CI95%: 1.51-1.88), social unrest (RR = 1.29, CI 95%: 1.04-1.58), overcrowding (RR = 1.36, CI 95%: 1.19-1.55) and inner city areas (RR = 1.92, CI 95% 1.48-2.50). Among the male non-users of intravenous drugs, no interaction between unemployment and age was found. Neighbourhoods with extreme poverty and inner city neighbourhoods showed a higher risk of tuberculosis (RR = 1.11, CI 95% 1.08-1.135 and RR = 1.80, CI95%: 1.51-2.14). Among the female non-users of intravenous drugs, a relationship was found in those of lesser age (RR = 1

    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.

    Bottled water consumption is increasing worldwide, despite its huge economic and environmental cost. We aim to describe personal and tap water quality determinants of bottled water use in the city of Barcelona. This cross-sectional study used data from the Health Survey of Barcelona in 2006 (N=5417 adults). The use of bottled water to drink and to cook was evaluated in relation to age, gender, educational level, district and levels of trihalomethanes (THMs), free chlorine, conductivity, chloride, sodium, pH, nitrate and aluminium in municipal tap water using Robust Poisson Regression. The prevalence of bottled water use to drink and cook was 53.9% and 6.7%, respectively. Chemical parameters in water had a large variability (interquartile range of THMs concentrations: 83.2-200.8μg/L) and were correlated between them, except aluminium. Drinking bottled water increased with educational level, while cooking with bottled water was higher among men than among women and decreased with age. After adjusting by these personal determinants, a dose-response relationship was found between concentrations of all chemicals except aluminium in tap water and bottled water use. The highest association was found for THMs, with a Prevalence Ratio of 2.00 (95%CI=1.86, 2.15) for drinking bottled water and 2.80 (95%CI=1.72, 4.58) for cooking with bottled water, among those with >150μg/L vs. <100μg/L THMs in tap water. More than half of Barcelona residents regularly drank bottled water, and the main determinant was the chemical composition of tap water, particularly THM level. Copyright © 2017.

    Proximity to road traffic involves higher health risks because of atmospheric pollutants. In addition to outdoor air, indoor air quality contributes to overall exposure. In the framework of the BREATHE study, indoor and outdoor air pollution was assessed in 39 schools in Barcelona. The study quantifies indoor and outdoor air quality during school hours of the BREATHE schools. High levels of fine particles (PM2.5), nitrogen dioxide (NO2), equivalent black carbon (EBC), ultrafine particle (UFP) number concentration and road traffic related trace metals were detected in school playgrounds and indoor environments. PM2.5 almost doubled (factor of 1.7) the usual urban background (UB) levels reported for Barcelona owing to high school-sourced PM2.5 contributions: [1] an indoor-generated source characterised mainly by organic carbon (OC) from organic textile fibres, cooking and other organic emissions, and by calcium and strontium (chalk dust) and; [2] mineral elements from sand-filled playgrounds, detected both indoors and outdoors. The levels of mineral elements are unusually high in PM2.5 because of the breakdown of mineral particles during playground activities. Moreover, anthropogenic PM components (such as OC and arsenic) are dry/wet deposited in this mineral matter. Therefore, PM2.5 cannot be considered a good tracer of traffic emissions in schools despite being influenced by them. On the other hand, outdoor NO2, EBC, UFP, and antimony appear to be good indicators of traffic emissions. The concentrations of NO2 are 1.2 times higher at schools than UB, suggesting the proximity of some schools to road traffic. Indoor levels of these traffic-sourced pollutants are very similar to those detected outdoors, indicating easy penetration of atmospheric pollutants. Spatial variation shows higher levels of EBC, NO2, UFP and, partially, PM2.5 in schools in the centre than in the outskirts of Barcelona, highlighting the influence of traffic emissions.

    The objective of this study was to analyse trends in socioeconomic inequalities in premature mortality in Barcelona from 1992 to 2011, accounting for population changes. We conducted a repeated cross-sectional study of the Barcelona population (25-64 years) using generalized linear mixed models for trend analysis, and found that socioeconomic inequalities in premature mortality persisted between neighbourhoods, but tended to diminish. However, the reduction in inequality was related to an increase in the number of foreign-born individuals mainly in socioeconomic disadvantaged neighbourhoods, in which the decrease in premature mortality was more marked. To study trends in geographical inequalities in mortality, it is essential to understand demographic changes occurred in different places related to local levels of deprivation.

    Patterns of cognitive deficit in single neuropsychological cases are common sources of evidence for theories of normal cognition. In particular, the working memory model has benefited from data obtained from a number of contrasting patients, in some cases resulting in modifications of the working memory model. In this paper, patterns of data from short-term memory patients and anarthric patients are compared with patterns of data from normal subjects. The patterns of patient data that were unlike those patterns typically found for groups of normal subjects, could be incorporated within a modified version of the articulatory loop component of the working memory model. However a small number of individual normal subjects also did not show the pattern that is reported on the basis of average performance of groups of normal subjects. This causes some difficulty in interpreting those data from such 'aberrant normal' patterns, and those data from single patients with functional cognitive deficits. The implications of these findings for the interpretation of neuropsychological data are discussed in the context of the working memory model, but with the intention of making a general point pertaining to the development of functional models of cognition. It is argued that single case studies should continue to provide a useful source of evidence, providing that care is exercised in considering the implications of such data for models of normal cognition.

    to assess therapeutic adherence to HAART amongst HIV positive inmates and its likely relationship with sets of different variables. longitudinal study carried out at the Men's Prison of Barcelona (Centro Penitenciario de Hombres de Barcelona). The prison data base, a semi-structured interview assessing socio-penal, demographic and clinical variables as well as treatment characteristics, and questionnaires on beliefs and emotional states were used. Adherence at the beginning of the study, and then after three and six months was also assessed. inmates presented with low levels of social support, and showed moderate agreement regarding care received from medical and health personnel. They considered the level of treatment complexity to be high and gave moderate relevance to treatment side effects. They presented high agreement with the potential benefits of continuing with the treatment and showed moderate perception of the severity of the illness. They also showed high levels of self efficacy where treatment monitoring was concerned. The emotional variables showed low blood pressure, depression, anger and fatigue. Adherence to antiretroviral treatment did not vary throughout the study period. Socio-cognitive variables that correlated with adherence at different times of the study were self efficacy, perceived benefits, treatment complexity and side effects. Emotional states that correlated with adherence were depression and fatigue. the relationship between self efficacy and adherence is frequently mentioned in studies on the prediction of HAART adherence. The relationship between the two factors of fatigue and sadness/depression and adherence was expected.

    In order to contribute to the sustainability of the outdoor environment, knowledge about the urban thermal bioclimate should be transferred into climatic guidelines for planning. The general framework of this study responds to the need of analyzing thermal bioclimate in Mediterranean climate regions and its influence as an urban design factor. The paper analyzes the background of the urban climate and thermal bioclimate conditions in Barcelona (Spain), through the effect of shade conditions and wind speed variations. Simulations of shade and wind speed variations were performed to evaluate changes in thermal bioclimate due to modifications in urban morphology. Air temperature, relative humidity, wind speed, and solar radiation for the period from January, 2001 to January, 2015 were used to calculate physiologically equivalent temperature (PET) using the RayMan model. The results demonstrate that shade is the most important strategy to improve urban microclimatic conditions. In Barcelona, human thermal comfort conditions can be improved by shade and wind speed increase in terms of PET above 23 °C and by a wind speed decrease for thresholds of PET below 18 °C. Heat stress situations can be mitigated by shade and wind speed increase in conditions above 35 and 45 °C, respectively. The results of the study are an important contribution for urban planners, due to their possibilities and potential for the description of microclimatic conditions in Mediterranean climate regions. The knowledge is useful for improved human thermal comfort conditions, from the suitable configuration of urban form and architecture.

    The influence of biomass burning (BB) aerosols, whether of regional or local origin, on fine aerosol levels in the Barcelona urban environment (Spain) was investigated. High-time resolved data on light-absorbing aerosols and inorganic tracers in PM2.5 were combined to this end during a dedicated sampling campaign carried out in winter 2011. The evaluation of PM inorganic components and equivalent black carbon evidenced that local-scale BB emissions were not detectable, whereas a source of K, different to vehicular traffic (road dust) and construction/demolition dust re-suspension, was detectable in the urban area. Source apportionment analysis evidenced the contribution from one source traced by S (62% of the source profile) and K (16% of the source profile), which was interpreted as regional-scale transport of secondary aerosols including BB contributions. The S/K ratio for this source (S/K = 4.4) indicated transport of the polluted air masses, as occurs from the rural areas towards the Barcelona urban environment. On average for the study period, the contribution of K-related aerosols from regional BB to PM2.5 levels in the urban environment was estimated as 1.7 μg/m3 as a daily mean, accounting for 8% of the PM2.5 mass during the winter period under study. The contribution from this source to urban aerosols should be lower on the annual scale.

    The Food Health Quality Research Program (Investigación de la Calidad Sanitaria de los Alimentos [ICSA]) of the Public Health Agency of Barcelona (Agencia de Salud Pública de Barcelona [ASPB]) was initiated in 1984 to carry out surveillance of certain chemical and microbiological parameters related to the sanitary and safety of foods sold in the city. The present article analyzes the importance of health surveillance and provides details of the uses of the ICSA program. The main aim of this program is to evaluate whether marketed foods comply with the absence and/or established tolerance levels of specific parameters. Nevertheless, the program is able to incorporate or suppress parameters or foods that pose emerging dangers or interests not represented in current legislation. Besides, the program not only obtains a view of the parameters studied at a specific time period in each report, but also accumulates data over time, allowing risk assessment, calculation of dietary intake of contaminants, analysis of tendencies, and evaluation of the effectiveness of regulations to reduce contaminants. The program can also help in the planning of food control programs. The information obtained is disseminated nationally and internationally and is included in dossiers of contaminants issued by national and European health agencies. This demonstrates that a locally-developed surveillance system can have a wider scope and broader objectives and can provide useful information for managers, administrations, economic operators and consumers.

    We aimed to analyse the prevalence of having multiple lifestyle risk behaviours (LRB) and the potential relationship between excess weight (including overweight and obesity) and cumulative multiple LRB among adolescents in Barcelona, Spain. A cross-sectional study was performed among a representative sample of 3,114 secondary school students in Barcelona. Height and weight were objectively measured and excess weight was defined in accordance with World Health Organization criteria. Information on screen time, breakfast, physical activity and sleep duration was obtained through a self-administered questionnaire. More than 80% of the students had at least two LRBs. In compulsory schooling, the adjusted prevalence ratio (aPR) of excess weight increased with a higher number of reported LRBs (four LRBs: aPR=1.56; 95% confidence interval: 1.19-2.05). These results highlight the importance of a multiple-behaviour approach in preventive programmes aimed at reducing adolescent obesity. Copyright © 2017 SESPAS. Publicado por Elsevier España, S.L.U.

    1991-03-01

    The determination of hospital patient costing adjusted by case-mix is one of the possible applications arising from the emergence of patient classification systems, such as Diagnosis Related Groups (DRGs). Most of the experiences up until now have given priority to the determination of the total costs by DRG, making it difficult to establish comparisons between hospitals. In this article, results of an experience in Barcelona with a direct patient costing model are presented, with these later being grouped into DRGs. Descriptive information is given together with statistical analysis of the intra-DRG variability and the relationship between costs and the length of stay. Patient costing systems represent a useful instrument for hospital management as they allow analyzing variation and its reasons at DRG level. It is in fact the primary level of information required in order to develop management control in hospitals.

    To analyze the incidence of perinatal sepsis due to group B streptococcus (GBS) as related to compliance with recommendations for its prevention issued by the Catalan Societies for Obstetrics, for Pediatrics, and for Infectious Diseases and Clinical Microbiology in 1997. The study was conducted from 1994 to 2001 in 10 Barcelona-area hospitals, where 157,848 live infants were born. GBS disease was diagnosed in 129 neonates. Incidence decreased by 86.1% over the study period, from 1.92 cases per 1000 live births in 1994 to 0.26 per 1000 in 2001 (p < 0.001). Changes in the characteristics of perinatal GBS disease were observed in the 18 cases diagnosed in the last 3 years, the time when prevention policies were operative. The incidence was lower (0.28 per 1000 vs. 1.19 for the previous 5 years, p <.00006), the proportion of mothers without risk factors was greater (77.8% vs. 55.9%, p 5 0.009), and premature neonates were not affected (0% vs. 12.6%, p 5 0.003); nevertheless, mortality was similar (5.5% vs. 4.5%, p 5 0.8). Among these 18 cases of sepsis, 9 can be considered failures inherent to the prevention policy and 9 failures of compliance. Only 3 hospitals had prevention policies in 1994, whereas all 10 used intrapartum prophylaxis based on screening results in 2001. A substantial decrease in the incidence of perinatal GBS disease coinciding with the application of prevention measures for this pathology has been registered in 10 participating hospitals over the 1994-2001 period.

    To date, very little data is available on the extensive, familiar, serological screening of Trypanosoma cruzi from infected-index cases. As it is a parasite with possibility of mother-to-child fetal transmission, the study of the offspring of chronically infected women has a special relevance. An observational study using a capture-recapture method that evaluates the offspring serological status of women diagnosed with T. cruzi infection (positive serology) in the northern metropolitan area of Barcelona during 2005-2016. A total of 238 women with positive serology for T. cruzi were identified. Of these, 117 (49.2%) could be localized. Their offspring summarized 300 individuals, of which 192 (64%) had serology records, with 23 positive for T. cruzi (11.98%; CI95%: 8.1-17.3). Among the 53 children born within the study area, 5 (9.8%, CI95%: 4.2-20.9) cases of vertical transmission were recorded. All children born as of 2010 (the starting year of mother screening) had serological outputs. Offspring of T. cruzi-seropositive women showed a high rate of seropositivity. The prevalence of vertical transmission is also remarkably high but comparable to that obtained in other European studies. The main source of loss was non-accessible women. It is reasonable to formaly include extensive, familiar, serological assessment in Chagas screening guidelines. In order to avoid losses, any eventual screening should be implemented at the time of the maternal diagnosis.

    Each year, hepatocellular carcinoma is diagnosed in more than half a million people worldwide and it is the fifth most common cancer in men and the seventh most common cancer in women. This article reviews the Barcelona-Clínic Liver Cancer protocol for the diagnosis, staging, and treatment of this disease, and four cases are presented for the discussion of the therapeutic approach. Understanding the diagnostic and therapeutic approaches to this disease is essential, especially if we keep in mind the quintessential basics of prevention and early detection. PMID:27812296

    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.

    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.

    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

    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.

    Acute limb ischemia is a complication of severe peripheral arterial disease that can be a threatening limb as well as life. Multiple procedures exist today to help revascularize extremities; however, even with the latest technologies, surgical amputation of the limb may still be necessary. Cryoamputation, or physiologic amputation, is a method used to treat patients who are hemodynamically unstable for the operating room and who are in need of urgent amputation owing to arterial ischemia. This procedure is used in the rare instance where not only a persons' limb is threatened, but also their life. This is a case study regarding one patient who presented to the hospital with limb-threatening ischemia who became hemodynamically unstable owing to the rhabdomyolysis associated with the ischemia of his lower extremity. Cryoamputation was used to stabilize the patient and prevent further deterioration, so that he could safely undergo surgical amputation of the limb without an increase in mortality risk. Cryoamputation must be followed by formal surgical amputation when the patient is hemodynamically stabilized. It is not a limb salvaging, procedure but it is a life-saving procedure. This case study demonstrates the usefulness of the procedure and discusses the technique used for cryoamputation.

    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.

    Study Objectives: To develop the Barcelona Sleepiness Index (BSI), an interviewer-administered instrument for assessing excessive daytime sleepiness (EDS) in sleep-disordered breathing (SDB) that correlates well with objective measures of EDS and which is sensitive to change with treatment. Methods: (1) Generation of a preliminary item list: Fifty-three consecutive SDB patients complaining of EDS and their bed partners were interviewed using a focus group methodology to generate a list of situations prone to cause sleepiness. Sixty different consecutive SDB patients were then evaluated using cognitive interviews to refine this list. (2) Construct validity: The maintenance of wakefulness test (MWT), the multiple sleep latency test (MSLT) and the sustained attention to response task (SART) test were used in an additional 98 consecutive SDB patients with and without EDS. The item combination that best correlated with the objective tests constituted the BSI. Cutoff values were determined to differentiate between patients with and without EDS. (3) Sensitivity to change: Thirty patients requiring continuous positive airway pressure (CPAP) were evaluated after satisfactory treatment. Results: A combination of two items, “in the morning, when relaxing” and “in the afternoon, standing inactive, in a public place,” presented the highest correlations with the MWT (r: −0.50, p < 0.001), the MSLT (r: −0.21, p = 0.07), and the SART (r: 0.27, p < 0.02) and constituted the BSI. The BSI significantly correlated with oxyhemoglobin saturation measures (nadir SpO2: r: −0.28, p = 0.01; CT 85: r: 0.23, p = 0.04) and showed a high sensitivity to change with CPAP treatment (t: 3.4, p = 0.002). A score of 2 or more identified patients with objective EDS (sensitivity = 64.9%, specificity = 72.1%). Conclusion: The Barcelona Sleepiness Index is a simple, brief instrument for measuring subjective EDS in SDB. Citation: Guaita M, Salamero M, Vilaseca I, Iranzo A, Montserrat JM

    Obsessional slowness is a rare psychiatric disorder with few treatment options and limited research to date. Some suggest that targeted behavioural interventions may reduce the time taken for functional daily activities. To examine whether a behavioural intervention would reduce the amount of time taken for an adolescent with obsessional slowness to walk to class. A single-subject A-B-A withdrawal design was incorporated into this case study. The treatment involved one-to-one pacing and prompting during the subject's walk to gym class. Walking times to gym class were measured during a baseline phase, during a one-month treatment phase, and during a post-treatment follow-up phase. The subject's walking times decreased during the treatment phase. Post-treatment walking times suggested a carry-over effect. This study adds to the sparse evidence on treatments for obsessional slowness and suggests occupation-based treatment options.

    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).

    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.

    Most of the studies of inequalities in mortality carried out in Spain have been ecological, due to the difficulty of obtaining good quality socioeconomic information at individual level. The objective of this study was to describe inequalities in mortality by social class, based on occupation, among men residents of Barcelona in 1993. A representative sample was obtained of men residents of Barcelona who died during the year 1993, aged between 15 and 65 years. It was a retrospective interview given to relatives of the deceased, or other closely related persons. The variables analysed were: age, education level, underlying cause of death, and social class based on occupation (manual and non-manual workers). Rates, relative risks (RRs) and their 95% confidence intervals (95% CIs) are presented by age groups and cause of death. The main results show that among young people, the excess of mortality due to infectious diseases is notable (RR: 1.9; 95% CI: 1.6-2.2), and also due to external causes (RR: 2.1; 95% CI: 1.8-2.4) among manual workers with respect to non-manual workers, mainly due to AIDS and drug overdose. No significant differences were found in mortality due to tumours. For respiratory and cardiovascular causes, there is an increase in mortality in the less favoured social classes, as also occurs for mortality due to diseases of the digestive system, particularly among young manual workers, with an RR: 2.6 (95% CI: 1.5-3.6) compared to non-manual workers. This study shows that it is necessary to continue exploring inequalities in health, but above all it is necessary to implement efficient preventive measures addressed mainly at young people in situations of disadvantage, in order to avoid the excess of avoidable mortality which is found.

    Breakfast is considered the most important meal of the day in an equilibrated diet. Skipping breakfast has been associated with overweight. This study aimed to describe overweight and obesity among high school students in Barcelona and to analyze their association with eating habits and sedentary behaviors. A cross-sectional study was performed in 2008 on a representative sample of high-school students in Barcelona (Spain). Overweight and obesity were defined using Body Mass Index (BMI), which was calculated from objective measurements. The prevalences of overweight and obesity were determined, and their association with eating habits, sedentary behaviors, and physical activity was analyzed using logistic regression models. A total of 3,089 students were analyzed (52% girls). The prevalence of overweight was 26.1% in boys (6.2% obese) and 20.6% in girls (3.7% obese). In both sexes, overweight was associated with being younger, having breakfast less often, being on a diet, and with a lower frequency of unhealthy food intake. Being on a diet and a lower unhealthy food intake were related to obesity in both sexes. Among boys, obesity was also associated with sedentary behaviors. The results show that overweight and obesity are a serious public health problem and confirm the importance of breakfast to prevent overweight. Moreover, these results allow us to expand our knowledge on the factors associated with overweight and obesity in order to improve current school preventive programs.

    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.

    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.

    Case studies can be useful in assessing and learning lessons from emergency situations. In this paper, different uses for disaster case studies, are explored with identification of potential pitfalls that should be avoided. In addition, ways to improve the rigor and significance of case studies are suggested. Case studies can be used as examples or as a research tool. If conducted properly, they can provide robust and compelling results. It is argued that sharing a common guide to conducting and writing case studies among all disaster risk reduction professionals could improve the quality of case study reports and thereby strengthen their value in advancing the prevention, preparedness, and management of disasters and emergencies.

    OAK-B135 Transmission System Improvements for Wind Energy Development in the Upper Midwest and Great Plains: Opportunities and Obstacles. This case study set out to ascertain the validity of three assumptions from the perspectives of stakeholders involved in wind energy and transmission issues in the Upper Midwest and Great Plains. The assumptions, and the stakeholders' reactions to each, are summarized below: Assumption 1--Transmission system improvements would provide significant benefits to the electricity network and its customers. Respondents acknowledge the potential for overall system benefits in the form of reduced line losses, improved grid stability and reliability, and enhanced ability to conduct spot market transactions. They also agree that these benefits relate to specific regional needs. However, there is disagreement over the extent of other benefits such as efficiency gains and cost savings from reduced line losses. Further, environmental and community interest groups point out that none of these benefits are realized without significant financial, environmental and social costs. Assumption 2--The benefits of transmission improvements would be helpful, but not confined, to wind power. All respondents agree that wind energy could benefit from transmission system improvements. But they also acknowledge, reluctantly, in the case of environmental stakeholders, that the benefits of an improved transmission system cannot be limited to environmentally preferable forms of generation. Some environmental and community advocate respondents also feel that transmission system improvement projects can be avoided altogether through energy conservation and efficiency measures, and by substituting wind energy for fossil generation. Assumption 3--Transmission alliances among stakeholders within and external to the wind community can provide benefits in the public interest.

    The objective is to establish the existence of possible correlations between cognitive measures using the a-BT, and functional measures in a population of normal to moderately severe demented subjects. A sample of 107 subjects (42 healthy controls, 19 subjects with mild cognitive impairment and 46 patients with probable Alzheimer's disease) were included in the present study. The instruments of the cognitive measure used was the abbreviated Barcelona Test (a-BT), a test of general cognitive function. Apart from that, the following functional scales, evaluating activities of daily living, were used: Rapid Disability Rating Scale-2 (RDRS-2), Blessed Dementia Rating Scale (BDRS), and Interview for Deterioration in Daily living in Dementia (IDDD). The statistical procedures were the correlations between cognitive and functional measures using Pearson's correlation coefficient. The correlations obtained between the cognitive and all functional measures were all highly significant (p < 0.0001) and consistently high, with correlations ranging between 0.72 and 0.80. Correlations between the a-BT and functional measures of more basic activities of daily living (RDRS-2, BDRS) were lower than those that included instrumental and some advanced activities of daily living (IDDD). The present paper establishes the existence of satisfactory correlations between the functional measures studied and the global scores of the a-BT. These correlations are applicable for groups of subjects with cognitive impairment that does not reach the threshold of a diagnosis of dementia as well as subjects suffering from Alzheimer's disease, at least up to moderately severe cases. The global score of the a-BT allows for some degree of prediction of the functional status of a subject with suspected Alzheimer's disease pathology evaluated.

    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.

    We report the case of patient MN, diagnosed with frontotemporal dementia, who exhibited a severe impairment in writing letters and words in upper-case print in the face of accurate production of the same stimuli in lower-case cursive. In contrast to her written production difficulties, MN was unimpaired in recognizing visually presented letters and words in upper-case print. We find a modest benefit of visual form cueing in the written production of upper-case letters, despite an inability to describe or report visual features of letters in any case or font. This case increases our understanding of the allographic level of letter-shape representation in written language production. It provides strong support for previous reports indicating the neural independence of different types of case and font-specific letter-shape information; it provides evidence that letter-shape production does not require explicit access to information about the visual attributes of letter shapes and, finally, it reveals the possibility of interaction between processes involved in letter-shape production and perception.

    Background 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. Material and Methods 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. Results 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. Conclusions 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.

    Continental shelves are recognized to play a key role in the biogeochemical cycle of carbon, linking terrestrial and marine carbon reservoirs. In this study we investigate the physical and biogeochemical processes that control the source, transport and fate of organic carbon (OC) in the continental shelf off Barcelona city, in the NW Mediterranean Sea. Surface sediment samples were collected from depths of 10-40 m during late summer and autumn 2012. Grain size and biogeochemical parameters such as OC, its stable isotope δ13C, total nitrogen (TN) and OC/TN ratios were analysed in size-fractionated sediments. The influence of environmental factors over the study area was determined using hydrological and oceanographic time series, together with video images of the Barcelona coast line and nearshore region. We have found a wide range of OC contents, from 0.13 to 8.68%, depending on water depth and sediment particle size. The highest OC concentration was always found in the clay fraction (<4 μm), followed by the sand fraction (>63 μm) that contained terrestrial plant debris. Wave activity, discharge of the Besòs River and the "Espigó" de Ginebra; outfall were the main mechanisms controlling the sorting of sediments by their grain size and thus the distribution of OC in the inner shelf off Barcelona. In addition, we observed that the organic matter in clay particles was progressively degraded seawards, probably because these particles remain suspended in the water column much more time compared to those that are heavier and, therefore, they are exposed for longer time periods to oxygenated conditions. Both OC/TN ratios and δ13C values found suggest that the organic matter preserved was predominantly land supplied.

    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 impact of Chagas disease is no longer restricted to endemic areas. The aim of this study is to evaluate a 2-year period of a vertical transmission screening program of Trypanosoma cruzi infection in a tertiary care hospital in Barcelona (Spain). Two enzyme-linked immunosorbent assays (recombinant and crude antigen) were performed in parallel to pregnant women at risk of T. cruzi infection. Discordant results were confirmed by a third diagnostic test. In the case of a positive result, the newborn was tested at birth and after 8 months of life. A total of 1,473 women met the inclusion criteria for the screening program with a resulting seroprevalence for T. cruzi of 3.5% (2.2–5.2% 95% confidence interval [95% CI]). One case of congenital infection was identified. Screening programs for vertically transmitted T. cruzi acute infection are beneficial in non-endemic areas for early detection and treatment of acute infection. PMID:22987653

    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.

    Congress has given NASA and the science community a reality check. The tight and ever shrinking budgets are trimming the fat from many space science programs. No longer can a Principal Investigator (PI) afford to waste development dollars on re-inventing spacecraft controllers, experiment/payload controllers, ground control systems, or test sets. Inheritance of the Ground Support Equipment (GSE) from one program to another is not a significant re-use of technology to develop a science mission in these times. Reduction of operational staff and highly autonomous experiments are needed to reduce the sustaining cost of a mission. The re-use of an infrastructure from one program to another is needed to truly attain the cost and time savings required. Interface and Control Systems, Inc. (ICS) has a long history of re-usable software. Navy, Air Force, and NASA programs have benefited from the re-use of a common control system from program to program. Several standardization efforts in the AIAA have adopted the Spacecraft Command Language (SCL) architecture as a point solution to satisfy requirements for re-use and autonomy. The Environmental Research Institute of Michigan (ERIM) has been a long-standing customer of ICS and are working on their 4th generation system using SCL. Much of the hardware and software infrastructure has been re-used from mission to mission with little cost for re-hosting a new experiment. The same software infrastructure has successfully been used on Clementine, and an end-to-end system is being deployed for the Far Ultraviolet Spectroscopic Explorer (FUSE) for Johns Hopkins University. A case study of the ERIM programs, Clementine and FUSE will be detailed in this paper.

    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

    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 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 μPM2.5 m-3). This is most probably due to the air conditioning system working in all carriages of the Barcelona metro during the whole year. On the platforms, levels were considerably higher, reaching mean levels of 59 and 88 μgPM2.5 m-3 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 more difficult due to the scarcity of data compared with PM2.5. Results showed clear PM daily cycles, with a drastic increase from 06:00 to 07:00 a.m., a diurnal maximum from 07:00 a.m. to 10:00 p.m., and marked decreases between 10:00 p.m. and 05:00 a.m. The elements with the highest enrichment are 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 inside the metro system, the contribution of commuting by metro

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

    2016-03-01

    Currently in the United States, the heavy majority of plug-in electric vehicle (PEV) sales have been in highly conducive, selected, metropolitan areas; opposed to more broad distribution across the country. The U.S. Department of Energy’s EV Everywhere Grand Challenge is looking carefully at the barriers and opportunities that exist to enable small and midsize communities to partake in the PEV market and benefit from the economic and environmental advantages of PEVs. In order to gain insight into these challenges and barriers, DOE selected a success story (i.e., Drive Electric Vermont) as the subject of this case study, as the state of Vermont is tied with Detroit, Michigan in having the highest percentage of 2014 (most recent complete data) PEV registrations for cold weather U.S. cities and has seen more than a sixfold increase in charging stations over the last three years. The overall objective of this case study was to use the lessons learned from Drive Electric Vermont to determine what activities are most effective at encouraging acquisitions of PEVs and deployment of charging infrastructure in small to midsize communities, prioritizing and sequencing their implementation, identifying robust means for extrapolation, and applying this understanding to other small to midsize communities across the nation. The Drive Electric Vermont Program was formed in 2012 with a goal of increasing the use of electrified transportation in Vermont through policy development, education and outreach, and infrastructure development. The Drive Electric Vermont Program can be broadly broken into four components: (1) strategic planning/leadership, (2) stakeholder/partnership development, (3) education and outreach, and (4) incentives. The early phases of the program focused heavily on strategic planning, and stakeholder and partnership development, followed by a transition to education and outreach activities, charging infrastructure development, and grant and incentive programs

  13. Pyourachus: study of two cases.

    2006-07-01

    The urachus, or median umbilical ligament, is a midline tubular structure that extends upward from the anterior dome of the bladder toward, the umbilicus and represents the vestigial remnant of at least two embryonic structures, the cloaca and the allantois. The tubular urachus normally involutes before birth, remaining as a fibrous band, however its persistence can give rise to various clinical problems, not only in infants and children but also in adults. We report two cases of pyourachus at our institute with a review of the clinical presentation, imaging findings and surgical management. Both our patients were young males, with haematuria being the presenting feature in one case which has not been previously described in literature.

  14. Air pollution and urinary thioether excretion in children of Barcelona

    1991-06-01

    The polluted environment found in highly industrialized areas and in big cities contains a great quantity of electrophilic (EC) and proelectrophilic (PEC) compounds, which largely contribute to the development of several pathological processes in humans. EC and PEC can be coupled to the cysteine moiety of glutathione spontaneously or by the glutathione S-transferase system (GST), giving nontoxic metabolites that can be eliminated as urinary thioethers (UT). Therefore one approach to establishing the degree of impact of EC and PEC on the human body is the analysis of UT in the population living in polluted environments. The work presented here has been carried out in the city of Barcelona with a group of 50 children living in a polluted area, over a 12-mo period. Our results demonstrate that UT are significantly higher when the amounts of air pollutants (AP) increase; although the level of contamination never exceeded the established safe limits, UT reached values similar to those found in people smoking more than 10 cigarettes/d. These results may contribute to establishing the maximal levels of contamination compatible with a healthy life, on the basis of patterns of true salubrity rather than on political and economic criteria.

    We report a case of massive associative visual agnosia. In the light of current theories of identification and semantic knowledge organization, a deficit involving both levels of structural description system and visual semantics must be assumed to explain the case. We suggest, in line with a previous case study, an alternative account in the framework of (non abstractive) episodic models of memory.

    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.

  19. Case study: a bridge across the paradigms.

    PubMed

    Luck, Lauretta; Jackson, Debra; Usher, Kim

    2006-06-01

    Case study as a teaching and research tool has an extensive history in health and social sciences. Despite its suitability for many of the research questions that face nurses, nurses have not fully embraced case study as a comprehensive approach for research. The vagaries of the real-life clinical setting can confound methodologically purist researchers. Case study provides a milieu in which nurse researchers can respond to these vagaries and move towards a paradigmatic openness. In this paper, we argue that case study offers, as yet, under-explored and under-utilised potential as a bridge across the traditional research paradigms. We argue that case study has broad research application and epistemological, ontological and methodological flexibility. When used as a research approach, case study is both the process and end product of research. It provides a delineated boundary for inquiry, and a structural process within which any methods appropriate to investigating a research area can be applied.

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

    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.

  5. Potential formation of bromophenols in Barcelona's tap water due to daily salt mine discharges and occasional phenol spills

    The presence of phenol and chlorinated phenols in drinking water has been shown to affect both taste and odor and to cause negative effects on health. The priority pollutants list issued by E.P.A. includes eleven of these compounds as suspected carcinogens. Little attention has been focussed on the presence of bromophenols. The presence of volatile brominated organic compounds has been demonstrated when bromide is present, due to chlorination. Similarly, brominated phenols might be formed during chlorination in the water works. More than 3 million inhabitants in the area of Barcelona drink water taken from Llobregat river. Quality of this raw water is strongly influenced by high contents of bromide coming from salt mines located in the upper course of the river. Phenol and phenolic compounds are usually found in raw water in the ppb range but occasional spills may increase the phenol content up to parts per million. This study shows the possibility of formation of bromophenols during normal chlorination conditions at Barcelona's water works plant.

    The evolution of trace metal pollution on the Barcelona city continental shelf during the last few decades was studied by analyzing the historical records of trace metals in sediment cores and surface sediment samples taken at the same locations in 1987 and in 2008. Polluted surface samples taken in 1987 reached enrichment factors of up to 490 for Hg, about 40 for Pb and Cd, and about 17 for Zn, Cr and Cu. The data show a decline of up to one order of magnitude in the trace metal content of surface sediments during the last few decades, with maximum enrichment factors of between 20 and 30 for Hg and Cd and between 5 and 12 for Zn, Cr, Pb and Cu. Although present-day pollution is still significant, it is evident that environmental regulations that are in place, including the operation since 1979 of wastewater treatment plants built in the Besòs River watershed, have drastically reduced the pollution levels in this highly populated and industrialized Mediterranean area. However, water discharge during heavy rain events exceeds the treatment capacity of the existing facilities, leading to the maintenance of still high levels of metals in sediments of the Barcelona city shelf.

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

    NASA Astrophysics Data System (ADS)

    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.

    Africa is the final continent to be affected by the nutrition transition and, as elsewhere, is characterized by the paradoxical coexistence of malnutrition and obesity. Several features of the obesity epidemic in Africa mirror those in other emerging nations: it penetrates the richer nations and urban areas first with a strong urban- rural gradient; initially it affects the wealthy, but later there is a demographic switch as obesity becomes a condition more associated with poverty, and it shares many of the same drivers related to the increasing affordability of highly refined oils and carbohydrates, and a move away from subsistence farm work and towards sedentary lifestyles. Africa also has some characteristics of the obesity epidemic that stand out from other regions such as: (1) excepting some areas of the Pacific, Africa is probably the only region in which obesity (especially among women) is viewed culturally as a positive and desirable trait, leading to major gender differences in obesity rates in many countries; (2) most of Africa has very low rates of obesity in children, and to date African obesity is mostly an adult syndrome; (3) Africans seem genetically prone to higher rates of diabetes and hypertension in association with obesity than Caucasians, but seem to be relatively protected from dislipidemias; (4) the case-specific deaths and disabilities from diabetes and hypertension in Africa are very high due to the paucity of health services and the strain that the 'double burden' of disease places on health systems.

  9. The effects of hot nights on mortality in Barcelona, Spain

    2017-08-01

    Heat-related effects on mortality have been widely analyzed using maximum and minimum temperatures as exposure variables. Nevertheless, the main focus is usually on the former with the minimum temperature being limited in use as far as human health effects are concerned. Therefore, new thermal indices were used in this research to describe the duration of night hours with air temperatures higher than the 95% percentile of the minimum temperature (hot night hours) and intensity as the summation of these air temperatures in degrees (hot night degrees). An exposure-response relationship between mortality due to natural, respiratory, and cardiovascular causes and summer night temperatures was assessed using data from the Barcelona region between 2003 and 2013. The non-linear relationship between the exposure and response variables was modeled using a distributed lag non-linear model. The estimated associations for both exposure variables and mortality shows a relationship with high and medium values that persist significantly up to a lag of 1-2 days. In mortality due to natural causes, an increase of 1.1% per 10% (CI95% 0.6-1.5) for hot night hours and 5.8% per each 10° (CI95% 3.5-8.2%) for hot night degrees is observed. The effects of hot night hours reach their maximum with 100% and lead to an increase by 9.2% (CI95% 5.3-13.1%). The hourly description of night heat effects reduced to a single indicator in duration and intensity is a new approach and shows a different perspective and significant heat-related effects on human health.

    2009-01-01

    The mitigation of the effects of on-road traffic emissions on urban air pollution is currently an environmental challenge. Air quality modeling has become a powerful tool to design environment-related strategies. A wide range of options is being proposed; such as the introduction of natural gas vehicles (NGV), biofuels or hydrogen vehicles. The impacts on air quality of introducing specific NGV fleets in Barcelona and Madrid (Spain) are assessed by means of the WRF-ARW/HERMES/CMAQ modeling system with high spatial-temporal resolution (1 km(2), 1 h). Seven emissions scenarios are defined taking into account the year 2004 vehicle fleet composition of the study areas and groups of vehicles susceptible of change under a realistic perspective. O(3) average concentration rises up to 1.3% in Barcelona and up to 2.5% in Madrid when introducing the emissions scenarios, due to the NO(x) reduction in VOC-controlled areas. Nevertheless, NO(2), PM10 and SO(2) average concentrations decrease, up to 6.1%, 1.5% and 6.6% in Barcelona and up to 20.6%, 8.7% and 14.9% in Madrid, respectively. Concerning SO(2) and PM10 reductions the most effective single scenario is the introduction of 50% of NGV instead of the oldest commercial vehicles; it also reduces NO(2) concentrations in Barcelona, however in Madrid lower levels are attained when substituting 10% of the private cars. This work introduces the WRF-ARW/HERMES/CMAQ modeling system as a useful management tool and proves that the air quality improvement plans must be designed considering the local characteristics.

    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, SO2, NO, NO2, O3 and CO. Temperature, SO2, NO, NO2, O3 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 SO2 maintained statistical significance (P=.008). We have detected an increase in hospital admissions for exacerbation of bronchiectasis with increases in the atmospheric concentration of SO2 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.

    The multifamily case studies that are the subject of this report were conducted to provide a better understanding of the approach taken by program operators in weatherizing large buildings. Because of significant variations in building construction and energy systems across the country, five states were selected based on their high level of multifamily weatherization. This report summarizes findings from case studies conducted by multifamily weatherization operations in five cities. The case studies were conducted between January and November 1994. Each of the case studies involved extensive interviews with the staff of weatherization subgrantees conducting multifamily weatherization, the inspection of 4 to 12 buildings weatherized between 1991 and 1993, and the analysis of savings and costs. The case studies focused on innovative techniques which appear to work well.

  11. Are nested case-control studies biased?

    PubMed Central

    Langholz, Bryan; Richardson, David

    2014-01-01

    It has been recently asserted that the nested case-control study design, in which case-control sets are sampled from cohort risk sets, can introduce bias (“study design bias”) when there are lagged exposures. The bases for this claim include a theoretic and an “empirical evaluation” argument. Both of these arguments are examined and found to be incorrect. Appropriate methods to explore the performance of nested case-control study designs, analysis methods, and compute power and sample size from an existing cohort are described. This empirical evaluation approach relies on simulating case-control outcomes from risk sets in the cohort from which the case-control study is to be performed. Because it is based on the underlying cohort structure, the empirical evaluation can provide an assessment that is tailored to the specific characteristics of the study under consideration. The methods are illustrated using samples from the Colorado Plateau uranium miners cohort. PMID:19289963

    The aim of this study is to provide an overview of the scientific activity of different psychoanalytic schools of thought in terms of the content and production of case studies published on ISI Web of Knowledge. Between March 2013 and November 2013, we contacted all case study authors included in the online archive of psychoanalytic and psychodynamic case studies (www.singlecasearchive.com) to inquire about their psychoanalytic orientation during their work with the patient. The response rate for this study was 45%. It appears that the two oldest psychoanalytic schools, Object-relations psychoanalysis and Ego psychology or "Classical psychoanalysis" dominate the literature of published case studies. However, most authors stated that they feel attached to two or more psychoanalytic schools of thought. This confirms that the theoretical pluralism in psychoanalysis stretches to the field of single case studies. The single case studies of each psychoanalytic school are described separately in terms of methodology, patient, therapist, or treatment features. We conclude that published case studies features are fairly similar across different psychoanalytic schools. The results of this study are not representative of all psychoanalytic schools, as some do not publish their work in ISI ranked journals.

    To describe the prevalence of e-cigarette users who use them in selected indoor public and workplaces, and private venues in Barcelona (Spain) in 2015. This is a cross-sectional study of a sample of e-cigarette users (≥ 18 years) from Barcelona (n = 600). We calculated the proportion of e-cigarette users who used the device in public and private settings (in the last 30 days). We fit multivariate logistic regression models adjusted for sex and age to calculate the odds ratios (OR) with their 95% confidence intervals (CI) of e-cigarette use by socio-demographic factors, dual use and nicotine-containing e-cigarettes. The highest proportion of e-cigarette users who used them in public places was found at restaurants or bars (69.4%) and nightclubs or pubs (55.4%). Also being current conventional tobacco smokers (dual users) was significantly associated with lower use of e-cigarettes in workplaces (OR = 0.61, 95%CI:0.41-0.91), restaurants (OR = 0.66, 95%CI:0.45-0.97) and nightclubs (OR = 0.56, 95%CI:0.37-0.86). Moreover, being a nicotine-containing e-cigarette user was associated with higher odds of using the device in workplaces (OR = 2.01, 95%CI:1.34-3.01), and lower odds of using it in nightclubs (OR = 0.56, 95%CI:0.39-0.82). 96.8% of the included e-cigarette users declared to use the device at home. Being a current tobacco smoker was associated with increased odds of using e-cigarettes at home (OR = 3.17, 95%CI:1.22-8.22). E-cigarette use in private settings and in public settings where their use is not regulated by law is high. Therefore, the public health administration in Spain should consider expanding the prohibition of e-cigarette use to indoor public places and should take into account the possibility of exposure to aerosol from e-cigarettes.

    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

    Hepatocellular carcinoma (HCC) is the main common primary tumour of the liver and it is usually associated with cirrhosis. The barcelona clinic liver cancer (BCLC) classification has been approved as guidance for HCC treatment algorithms by the European Association for the Study of Liver and the American Association for the Study of Liver Disease. According to this algorithm, hepatic resection should be performed only in patients with small single tumours of 2-3 cm without signs of portal hypertension (PHT) or hyperbilirubinemia. BCLC classification has been criticised and many studies have shown that multiple tumors and large tumors, as wide as those with macrovascular infiltration and PHT, could benefit from liver resection. Consequently, treatment guidelines should be revised and patients with intermediate/advanced stage HCC, when technically resectable, should receive the opportunity to be treated with radical surgical treatment. Nevertheless, the surgical treatment of HCC on cirrhosis is complex: The goal to be oncologically radical has always to be balanced with the necessity to minimize organ damage. The aim of this review was to analyze when and how liver resection could be indicated beyond BCLC indication. In particular, the role of multidisciplinary approach to assure a proper indication, of the intraoperative ultrasound for intra-operative restaging and resection guidance and of laparoscopy to minimize surgical trauma have been enhanced.

    The Drugs Advice Service (SOD in its Catalan acronym) in Barcelona (Catalonia, Spain) provides an Information and Guidance Program (IGP) for teenagers, and an Alternative Measures Program (AMP) targeting minors fined for consumption / possession of illegal drugs in public spaces. This study describes these programs and compares the profiles of their users. Cross-sectional descriptive study of 1,010 people discharged from the two SOD programs in 2008-10 after screening for psychiatric disorders and addiction and an extended brief intervention for subjects without pathology. The profiles of the users were compared, and age-specific rates of AMP use were calculated. Cannabis causes 89.9% of entries in the SOD. The proportion of IGP users with high risk criteria for cannabis is 13.3% and with risk for alcohol 11.3%, while in AMP it is 8.9%, and 4%. Criteria for substance dependence or abuse or another psychiatric disorder caused referral of 6% of AMP users and 38% of IGP users. Adolescents in the AMP had a pattern of cannabis use (and often of alcohol) of low or moderate risk, compared to IGP. Beyond the value of the indicated prevention intervention, the programmes facilitate the early detection and referral of problematic substance use and mental disorders in early stages.

    Hepatocellular carcinoma (HCC) is the sixth most common cancer and the third most common cause of cancer-related deaths worldwide. The Barcelona Clinic Liver Cancer (BCLC) classification has been endorsed as the optimal staging system and treatment algorithm for HCC by the European Association for the Study of Liver Disease and the American Association for the Study of Liver Disease. However, in real life, the majority of patients who are not considered ideal candidates based on the BCLC guideline still were performed hepatic resection nowadays, which means many hepatic surgeons all around the world do not follow the BCLC guidelines. The accuracy and application of the BCLC classification has constantly been challenged by many clinicians. From the surgeons’ perspectives, we herein put forward some comments on the BCLC classification concerning subjectivity of the assessment criteria, comprehensiveness of the staging definition and accuracy of the therapeutic recommendations. We hope to further discuss with peers and colleagues with the aim to make the BCLC classification more applicable to clinical practice in the future. PMID:26217077

    STUDY OBJECTIVE: To determine the distribution of opioid use prevalence in small areas and its relation with socioeconomic indicators. DESIGN: Capture-recapture was applied using data from the Barcelona Drug Information System for 1993 (treatment demands, hospital emergency room visits, deaths from heroin acute adverse reaction and pre-trial prison admissions). To avoid dependence between sources, a log-linear regression model with interactions was fitted. For small neighbourhoods, where capture-recapture estimates were not obtainable, the Heroin Problem Index (HPI) was used to predict prevalence rates from a regression model. The correlation between estimated opioid use prevalence by neighbourhoods and their socioeconomic level was computed. MAIN RESULTS: The city's estimated prevalence was 12.9 opioid addicts per 1000 inhabitants aged 15 to 44 years (95% CI: 10.1, 17.2), which represents 9176 persons. The highest rate was found in the inner city neighbourhood. Comparing rates obtained for each neighbourhood with their unemployment rates, a high correlation coefficient was obtained (r = 0.80, p < 0.001). CONCLUSION: The main contribution of this study is that of combining capture-recapture with the HPI to produce small area prevalence estimates, which would not have been possible using only one method. Areas with higher socioeconomic status showed proportionally low addiction prevalences, but in depressed areas, prevalences varied widely.   PMID:10562867

    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

    Background. Polyorchidism, alternatively supernumerary testes (SNT), is a condition where an individual is born with more than two testicles. This congenital anomaly is quite rare and the literature has described various presentations. Questions/Purposes. To our knowledge, this presentation of polyorchidism has yet to be described in the literature. The goal of this case study is to add to the pediatric, general, and urologic surgery's body of knowledge of the subject matter. Case Study. A nine-month-old boy was admitted for an impalpable right testis and phimosis. At the time of surgical exploration, there appeared to be polyorchid testis on the right-hand side, with three masses that potentially appeared to be undescended testes. Discussion. Proponents of a conservative approach argue that infertility is common in patients with polyorchidism and, by preserving a potentially functional SNT, there may be improved spermatogenesis. When performing definitive surgical treatment, meticulous intra-abdominal and intrainguinal exploration must be undertaken. Orchiopexy should be performed to reduce the chances of torsion, malignancy, and infertility. Conclusion. Our case is important to the literature as it is the first known case of polyorchidism with 3 SNT on the right side, located intra-abdominally, and in a patient less than 1 year of age.

    Observational studies, such as cohort and case-control studies, are valuable instruments in evidence-based medicine. Case-control studies, in particular, are becoming increasingly popular in the neurosurgical literature due to their low cost and relative ease of execution; however, no one has yet systematically assessed these types of studies for quality in methodology and reporting. The authors performed a literature search using PubMed/MEDLINE to identify all studies that explicitly identified themselves as "case-control" and were published in the JNS Publishing Group journals (Journal of Neurosurgery, Journal of Neurosurgery: Pediatrics, Journal of Neurosurgery: Spine, and Neurosurgical Focus) or Neurosurgery. Each paper was evaluated for 22 descriptive variables and then categorized as having either met or missed the basic definition of a case-control study. All studies that evaluated risk factors for a well-defined outcome were considered true case-control studies. The authors sought to identify key features or phrases that were or were not predictive of a true case-control study. Those papers that satisfied the definition were further evaluated using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist. The search detected 67 papers that met the inclusion criteria, of which 32 (48%) represented true case-control studies. The frequency of true case-control studies has not changed with time. Use of odds ratios (ORs) and logistic regression (LR) analysis were strong positive predictors of true case-control studies (for odds ratios, OR 15.33 and 95% CI 4.52-51.97; for logistic regression analysis, OR 8.77 and 95% CI 2.69-28.56). Conversely, negative predictors included focus on a procedure/intervention (OR 0.35, 95% CI 0.13-0.998) and use of the word "outcome" in the Results section (OR 0.23, 95% CI 0.082-0.65). After exclusion of nested case-control studies, the negative correlation between focus on a procedure

    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 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.

    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.

  17. The Application of Urban System Analysis To The Seismic Risk Assessment of Barcelona

    NASA Astrophysics Data System (ADS)

    Irizarry, J.; Marturia, J.; Mena, U.

    The Urban System Analysis methodology developed by an international team directed by the BRGM (France) within the GEMITIS research program (1996-1999) consists of a global and integrated risk reduction strategy in order to improve the risk assessment effectiveness through the use of a geographical information system (GIS). A typical seismic risk analysis evaluates only the direct impacts of the earthquake, but gives few information about how to improve preventive effectiveness because it does not provide any data about the indirect consequences of an earthquake. This new methodology proposes to complete the scenario generation process by focusing physical vulnerability assessment on the essential elements for urban functioning. Besides it gives rational bases for the definition of appropriate risk management and preventive action plans. This study presents a first stage of the application of the Urban System Analysis method to the city of Barcelona. The elements at risk in the city like the residential, commercial, administrative, and industrials areas are identified and analyzed to define the weak points within its urban system. Then the most critical elements within the city's urban system will be identified to establish priorities for risk managements plans in the city.

    The organisers of the Barcelona World Race (BWR), the Institute of Marine Sciences (ICM-CSIC) and the Maritime Catalan Forum (FMC) agreed on equiping the FMC boat, participating in the race, with a SeaBird MiniCTD. The idea was for the first time to explore how such oceanic races could help to monitor surface temperature and salinity all around the world ocean in real time. The boat spent 112 days to complete the rond trip, sending 12-30 real-time samples/day via ARGOS satellites, using a transmitter developed at the ICM. Data was also stored in the instrument, at 192 samples/day to allow further final global analyses. In the SMOS (Soil Moisture and Ocean Salinity) satellite mission processing chain, sea surface salinity (SSS) values are retrieved from brightness temperature data at level 2 (L2). Global maps of SSS are being generated at level 3 (L3) using spatial and temporal weighted averages. Finally, improved representations of the SSS field are obtained at level 4 (L4) where satellite data is blended with data from other sensors. In the present study, validation of L2, L3 and L4 products using data from BWR and ARGO buoys is presented, covering the race period from January to April 2011. Differences between these two sets of data are also investigated as the uppermost robust measurements from Argo profilers have larger depths than the ones associated to the BWR boat.

    In order to assess heavy metal mobility in dredged harbour sediments, six superficial sediment samples covering a range of pollution levels and environments were collected in Barcelona Harbour. Samples were characterised in terms of major compounds (Al, Ca, Fe, Mn, Si, Ti, Mg, K and Na); total C, N and S contents; organic matter; and water content. Pseudo-total trace metal contents were assessed after aqua regia digestion (ISO 11466:1995). The modified BCR three-step sequential extraction procedure (BCR-SEP) was applied, and both major compounds (Al, Ca, Fe and Mn) and trace metals (Cd, Cr, Cu, Ni, Pb and Zn) were determined in the different extracts. Both the pseudo-total digestion method and the BCR-SEP were validated using two sediment certified materials from lakes (BCR CRM 701 and BCR CRM 601). The highest metal concentrations were observed in one of the sampling points which receives an urban discharge. The observed mobility order (percentage of metal extracted in the first step) of the six trace metals studied was Cd>Zn>Pb>Cu>Ni>Cr. The good agreement observed with the results obtained as the sum of the four steps (extractable+residue) and the pseudo-total content shows that laboratory working conditions were under control.

    Background The Barcelona Clinic Liver Cancer (BCLC) classification of hepatocellular carcinoma (HCC) has proved useful in the management of HCC patients. However, BCLC-recommended first-line treatment is not always applicable in clinical practice. Objective We performed a multicentre retrospective analysis of reasons for deviation from first-line treatment in 2008–2012. Methods One to three-year survival data were analysed using Kaplan-Meier method. Results A total of 407 consecutive HCC patients (66.6 ± 3 years, 83% male) with cirrhosis were included. Tumours were detected during surveillance in 53% of patients, grouped as Child-Pugh A (67%), B (25%) and C (8%); and BCLC A (including stage 0, 44%), B (26%), C (15%) and D (15%). In 31% of patients, first-line treatment was not feasible (51% in early stages) due to: technical reasons (74%); patient non-conformity (20%); medical decision (3%); and disease progression (3%). One to three-year survival of patients not receiving the recommended first-line treatment was similar to that of patients treated according to BCLC recommendations (log-rank, p = 0.229). Conclusion In real-life practice one-third of HCC patients could not receive first-line BCLC treatment. In our cohort of patients, similar short and medium-term survival was observed. Long-term prospective studies are required to determine the best alternative treatment option when BCLC first-line treatment is not feasible. PMID:26279838

  1. 3D elastic full waveform inversion: case study from a land seismic survey

    Full Waveform Inversion (FWI) is one of the most advanced processing methods that is recently reaching a mature state after years of solving theoretical and technical issues such as the non-uniqueness of the solution and harnessing the huge computational power required by realistic scenarios. BSIT (Barcelona Subsurface Imaging Tools, www.bsc.es/bsit) includes a FWI algorithm that can tackle with very complex problems involving large datasets. We present here the application of this system to a 3D dataset acquired to constrain the shallow subsurface. This is where the wavefield is the most complicated, because most of the wavefield conversions takes place in the shallow region and also because the media is much more laterally heterogeneous. With this in mind, at least isotropic elastic approximation would be suitable as kernel engine for FWI. The current study explores the possibilities to apply elastic isotropic FWI using only the vertical component of the recorded seismograms. The survey covers an area of 500×500 m2, and consists in a receivers grid of 10 m×20 m combined with a 250 kg accelerated weight-drop as source on a displaced grid of 20 m×20 m. One of the main challenges in this case study is the costly 3D modeling that includes topography and substantial free surface effects. FWI is applied to a data subset (shooting lines 4 to 12), and is performed for 3 frequencies ranging from 15 to 25 Hz. The starting models are obtained from travel-time tomography and the all computation is run on 75 nodes of Mare Nostrum supercomputer during 3 days. The resulting models provide a higher resolution of the subsurface structures, and show a good correlation with the available borehole measurements. FWI allows to extend in a reliable way this 1D knowledge (borehole) to 3D.

    2016-11-26

    The value of case studies for theory building is still doubted in psychology. The paper argues for the importance of case studies and the possibility of generalizing from these for a specific sociocultural understanding of human development. The paper first clarifies the notion of abduction within case studies, drawing on pragmatists James and Peirce and expanding it with the work of Lewin, and argues that it is the core mechanism that allows generalization from case studies. The second section presents the possibility of generalizing from individual single case studies, for which not only the subjective perspective, but also the dynamics by which the social and cultural environment guide and enable the person's development, have to be accounted for. The third section elaborates the question of institutional case studies, where the challenge is to account both for institutional dynamics, and for persons' trajectories within; this is exemplified with an ongoing study on the process of obtaining citizenship in Switzerland. The paper briefly concludes by highlighting two possible implications of the paper, one concerning the process of theoretical reasoning, the other, the fact that sociocultural psychology could itself be seen as an institution in-the-making.

    Bioethics education often includes the study of short stories, novels, plays, and films, because such materials present case examples that can highlight relevant issues and questions especially vividly for a wide range of students. In addition, creative writing is widely used in the education of health professional students and in continuing education settings for health professionals. There are very few academic or professional disciplines that do not use case studies, but the case study in dialogic form has not been standard practice for thousands of years. Dramatic arts casuistry-the creation and performance of short case studies designed specifically to raise bioethics issues for discussion-represents an application of literature and the medical humanities that is both unique and uniquely valuable. This essay describes the development and history of a course that has been successfully taught to medical students and graduate bioethics students, in which the class researches, writes, and performs a case study designed to elicit reflection and discussion about a topic and set of bioethics issues of current interest to both academic and general audiences. The model is also suited to the presentation and discussion of existing case studies, both live and via on-demand audio.

    The first step in the restoration of a medieval stained glass window is the evaluation of its degree of degradation. This implies the study of the chemical composition of the stained glass as well as the new mineral phases developed on its surface (patinas). Patinas are clearly related to glass composition, time, environmental conditions, microenvironments developed in local zones, bioactivity, physical and chemical factors, etc. This study was carried out on patinas developed in selected Na-rich stained glass of the Santa Maria de Pedralbes Monastery (Barcelona, Spain). The location of this monument in the city (about 5 km from the shoreline and close to the Collserola hill flank) helped to determine the environmental conditions in which patinas developed. The aim of our study was to characterize the patinas formed on the surface of the selected glass of this monastery in order to understand the role of the chemical composition of the original glass (Na-rich) as well as the environmental conditions in which they developed. Powdered samples of two different color-type patinas (ochre-orange and brownish) were collected in the external and internal parts of the stained glass windows of the Prebystery and Chapter House of the Pedralbes Monastery by using a precision (odontological) drill. These patinas were subsequently analyzed by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). XRD analyses evidenced the presence of sulfates (gypsum and thenardite), calcite, Ca-oxalates (whewellite and weddellite), and quartz forming part of the patinas. Although these mineral phases can be found in both color-type patinas, whewellite and thenardite are more common in the ochre-orange patinas. The results obtained were validated by the FTIR measurements. It has been observed, when thenardite is present, that gypsum occurs as traces. Thenardite is in most of the cases associated with whewellite and mainly occurs in the internal parts of the glass. In

    Many faculty members consider using case studies but not all end up using them. We provide a brief review of what cases are intended to do and identify three ways in which they can be used. We then use an example to illustrate how we have used the case study method in teaching business demography. Among other benefits, we note that the case studies method not only encourages the acquisition of skills by students, but can be used to promote "deep structure learning," an approach naturally accommodates other features associated with the case studies method-the development of critical thinking skills, the use of real world problems, the emphasis of concepts over mechanics, writing and presentation skills, active cooperative learning and the "worthwhileness" of a course. As noted by others, we understand the limitations of the case study method. However, given its strengths, we believe it has a place in the instructional toolbox for courses in business demography. The fact that courses we teach is a testament to our perceived efficacy of this tool.

    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.

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%).

  19. Comparison of parallel temperature measurements from conventional and automatic weather stations at Fabra Observatory (Barcelona).

    2013-04-01

    Fabra Observatory , located in a promontory at 411 meters above sea level in the outskirts of Barcelona, hosts a continuous climate record since 1913. Additionally, it has been recording since 1996 simultaneous temperature and precipitation data with conventional instruments and automated systems. The automatization of recording sites employed with climatological purposes is happening elsewhere in the country and across the globe. Unfortunately, in most cases long lasting parallel measurements, are not kept. Thereafter, this site offers an excellent opportunity to study the impact of the introduction of Automatic Weather Stations (AWS). The conventional station (CON) equips a liquid in glass thermometer, located inside a standard Stevenson screen. The automatic measurements (AWS) have been taken using MCV-STA sensors sheltered in a MCV small plate-like ventilated screen between 1996 and the end of July 2007. For our analysis, this MCV period is split in two (T1, T2) due to an obvious jump in the differences AWS-CON in October 2002, produced by unknown reasons. From August 2007 to the present (T3), a Vaisala HMP45AL sensor was placed inside a Stevenson Screen and used for automatic measurements. For daily maximum temperatures, the median differences reach 3.2°C in T1, 1.1°C in T2 and merely -0.1°C in T3. In this later period, 94% of the differences are comprised in a ±0.5°C range, compared to 23% in T2 and only 6% in T1. It is interesting to note how the overheating of the MCV screen dominates the difference series, as 85% of the AWS values taken in T1 and T2 are warmer than the conventional measurements, contrasting with only 27% of cases during T3, when the automated measurements were taken inside a Stevenson screen. These differences are highly temperature dependent: low (high) AWS temperatures are associated with small (large) differences with the CON series. This effect is also evident if temperatures are analyzed by seasons: summer differences are much

    The vitreous of three patients with asteroïd hyalosis (average age: 57 years) was obtained by a two-hand closed pars plana vitrectomy. Asteroïd hyalosis was associated with alcoholic neuropathy in the first case, long standing retinal detachment in the second case, and diabetes mellitus in the third case. The visual acuity before and after the surgical procedure improved from 1.2/6 to 6/6 in the first case, from light perception to 0.3/6 in the second case, from 0.6/6 to 4.8/6 in the third case. The vitreous was studied by different ultrastructural technics : transmission electron microscopy (T.E.M.) scanning electron microscopy (S.E.M.) and electron diffraction X ray analysis (E.D.A.X.). By S.E.M. the asteroïd bodies appeared as rounded structures with an irregular surface connected to each other by fibrous strands among sodium chloride crystals. No cellular remnants were observed. By T.E.M. the asteroïd bodies were composed of interwinned ribbons of multilaminar membranes with a periodicity (10 to 60 A) characteristic of complex lipids, especially phospholipids. At the edge of the ribbons there were dots and sometimes clumps of opaque material that tended to crack out of the specimen with the heat of the electron beam. T.E.M. study disclosed the irregular disposition of the calcific bodies. By E.D.A.X. the calcific composition of the rounded structures could be determined : calcium and phosphorus were the main elements detectable in asteroïd bodies of all sizes for all three patients. The average calcium counts for the three successive cases were : 18, 30, 43 and for phosphorus : 9, 14, 26. Potassium was found in the first case, and sulfur in the third case.(ABSTRACT TRUNCATED AT 250 WORDS)

    EPA Pesticide Factsheets

    The draft document is intended to be used as part of a process to identify what is known and, more importantly, what is not yet known that could be of value in assessing the broad implications of specific nanomaterials. Like previous case studies (see History/ Chronology below), this draft case study on multiwalled carbon nanotubes (MWCNTs) is based on the comprehensive environmental assessment (CEA) approach, which consists of both a framework and a process. Unlike previous case studies this case study incorporates information about a traditional (i.e., “non-nano-enabled”) product, against which the MWCNT flame-retardant coating applied to upholstery textiles (i.e., the “nano-enabled” product) can be compared. The comparative element serves dual-purposes: 1) to provide a more robust database that facilitates identification of data gaps related to the nano-enabled product and 2) to provide a context for identifying key factors and data gaps for future efforts to evaluate risk-related trade-offs between a nano-enabled and non-nano-enabled product. This draft case study does not represent a completed or even a preliminary assessment of MWCNTs; rather, it uses the CEA framework to structure information from available literature and other resources (e.g., government reports) on the product life cycle, fate and transport processes in various environmental media, exposure-dose characterization, and impacts in human, ecological, and environmental receptors.

Unlike previous case studies this case study incorporates information about a traditional (i.e., “non-nano-enabled”) product, against which the MWCNT flame-retardant coating applied to upholstery textiles (i.e., the “nano-enabled” product) can be compared. The comparative element serves dual-purposes: 1) to provide a more robust database that facilitates identification of data gaps related to the nano-enabled product and 2) to provide a context for identifying key factors and data gaps for future efforts to evaluate risk-related trade-offs between a nano-enabled and non-nano-enabled product. This draft case study does not represent a completed or even a preliminary assessment of MWCNTs; rather, it uses the CEA framework to structure information from available literature and other resources (e.g., government reports) on the product life cycle, fate and transport processes in various environmental media, exposure-dose characterization, and impacts in human, ecological, and environmental receptors.

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

    NASA Astrophysics Data System (ADS)

    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.

    The detailed characterization of fractured media in the shallow subsurface is becoming important. The detailed knowledge of the fracture network is mandatory in any hydrogeological model to constrain the potential pathways for water circulation. The geophysical methodolgies can provide a detailed image of the fractured rock and also the 3D distribution of physical properties. Two case studies are discussed in this work. The characterization of fractures in a waste disposal site and, the design and construction of a subway tunnel. In the first case, a multiseismic experiment was carried out in an old abandoned uranium mine. 2D and 3D seismic experiments including VSP, surface seismic reflection and travel time seismic tomography provided a 3D image of the internal structure of a granitic massif for hydrogeological studies of the preferred paths for the migration of contaminants. The tectonic stability of the site was also addressed by means of seismic measurements. The joint interpretation of all the available data enabled the interpretation of the low velocity anomalies in the 3D seismic tomography image as the fragile fractures and the alteration associated to them. A 3D image of the geometry of the heterogeneous weathered surface layer was also obtained. This surface is controlled by the complex network of faults and dykes observed in the area. The second case study involves 2D and 3D seismic experiments to aid the horizontal drilling of tunnels for a new subway line in Barcelona (Spain). Seismic data acquisition in a densely populated city is very difficult. The street layout determines the geometry of the acquisition experiments. The instrumentation can not always be located on the surface projection of the tunnel trace, therefore, pseudo 3D acquisition is required, deploying the instrumentation were it is possible. Furthermore, the shallow subsurface features extremely heterogeneous "weathered" layer of variable thickness (building fundations, sewage system

    As a continuation from summer 2012, the Shuttle Case Study Collection has been developed using lessons learned documented by NASA engineers, analysts, and contractors. Decades of information related to processing and launching the Space Shuttle is gathered into a single database to provide educators with an alternative means to teach real-world engineering processes. The goal is to provide additional engineering materials that enhance critical thinking, decision making, and problem solving skills. During this second phase of the project, the Shuttle Case Study Collection website was developed. Extensive HTML coding to link downloadable documents, videos, and images was required, as was training to learn NASA's Content Management System (CMS) for website design. As the final stage of the collection development, the website is designed to allow for distribution of information to the public as well as for case study report submissions from other educators online.

Students then develop their own case study, integrating ethical components. I want to expose my students to this way of thinking because I see technology being driven by the Jurassic Park phenomenon, "Your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should," and want future physicians grounded in a sense of how their actions relate to the greater good.

    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.

    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.

    2015-12-01

    Necrotizing fasciitis represents a group of highly lethal infections characterized by rapidly progressing inflammation and necrosis. The aim of the study was to analyze the clinical profile, microbial flora, and predisposing risk factors in patients with necrotizing fasciitis. Lastly, we aimed to formulate a protocol for management of necrotizing fasciitis. Forty-eight cases of necrotizing fasciitis patients who reported to our hospital between April 2007 and September 2009 were included in the study. The commonest predisposing factors were age greater than 50 years (58 % cases) and diabetes mellitus (52 % cases). The commonest site involved was extremity (70.8 %). Majority of infections were polymicrobial (87.5 %). Repeated aggressive debridement was the commonest surgical procedure performed. Early and aggressive surgical debridement, often in multiple sittings, supplemented by appropriate antibiotics and supportive therapy, forms the key to a successful outcome in necrotizing fasciitis.

    The following case studies demonstrate the application of self-assessment techniques. The selection of procedures reported here is not meant to imply necessarily that these procedures are more or less effective or more widely used than other available self-assessment tests, but rather to illustrate the various purposes for which self-assessment tools may be employed. Case 1 illustrates the contribution of data obtained from the Hearing Performance Inventory (Giolas, Owens, Lamb, & Shubert, 1979) in the management and counseling of a severely hearing impaired adult. Case 2 involves the use of the Hearing Problem Inventory developed by Hutton in Atlanta (HPI-A, Hutton, 1987). Application of the Self-Assessment of Communication (SAC) and Significant Other Assessment of Communication (SOAC) (Schow and Nerbonne, 1982) is shown in Case 3, whereas Case 4 demonstrates the usefulness of the Hearing Handicap Inventory for the Elderly (HHIE, Ventry and Weinstein, 1982). Both the SAC/SOAC and HHIE batteries involve problem cases associated with hearing aid fitting and assessment of benefit. The final illustration (Case 5) is a report on the Children's Auditory Processing Performance Scale (CHAPPS), a new questionnaire developed by Smoski, Brunt, and Tannahill/ISHA (1987) for assessing parent's judgment of children's listening abilities (Appendix). The versatility of self-assessment applications across a broad assortment of impairment levels, age groups, and clinical settings is demonstrated in these cases. Hopefully the reader will see more clearly the application and value of these and other non-audiometric techniques and will be motivated to increase the use of self-assessment tools in the individual work setting.

  1. Climatology of ozone ``mini-hole'' events and their influence on UV solar radiation in Barcelona (Spain)

    NASA Astrophysics Data System (ADS)

    2009-03-01

    The total ozone column (TOC) shows a strong annual cycle, so the threshold to define its lower values is better characterized as deviations from local climatological mean levels. A complete analysis of the effects of low total ozone on the UV radiation measured in Barcelona (Northeast of Spain) is described in the present work. The ozone "mini-holes" climatology in Barcelona, obtained from the daily ozone satellite data series (1978-2006), shows a seasonal behaviour with a maximum number of episodes in winter and early spring. Nevertheless there are a great number of events in the study area during September, when the UV irradiance reaching the Earth's surface is still high and consequently the biological effects such as erythema could be more important. In fact, daily low ozone columnar contents in comparison with climatological means are detected throughout the year generally associated to weather systems passing. The deepest ozone "mini-hole" reported in the area was in 2004. It lasted three days with a minimum on 10 January, when daily TOC was 40% lower than the January climatological mean. During those days under cloud-free conditions the aerosol properties remained constant indicating that only low ozone levels were responsible of the increase in UV solar radiation. The erythemal irradiance at noon was 36% higher than the day before the extreme low ozone event. Although in absolute terms this increase is high, the erythemal effects are not so considerable because the UV levels in winter are low. On the other hand, the "mini-hole" event observed in this area at the end of spring had more harmful biological consequences although the ozone decrease was not so great: on 20 April 2004, low ozone levels and high solar elevation favoured the increase in UVB radiation detected by an operative spectroradiometer. At 300 nm, the irradiance was 80% higher than the day before, declining to 31% at 305 nm. In this occasion the UV Index at 12 UTC increased in one unit.

    Neuropsychological assessment in individuals with intellectual disability is of utmost importance in order to determine the cognitive deficits underlying brain dysfunction and limiting intellectual functioning and adaptive behavior. However, no neuropsychological batteries in Spanish language have been created and validated for this population. To adapt the 'programa integrado de exploracion neuropsicologica-test Barcelona' and to validate the new version, the Barcelona Test for Intellectual Disability (TB-DI). To create normative data for its clinical use. The original test was modified based on data from a pilot sample of 65 individuals with intellectual disability. In order to study the psychometric properties of the TB-DI, it was administered to a sample of 170 individuals with intellectual disability and to a group of 60 individuals without it. The relevant variables for stratification of normative data were determined by means of regression models. The TB-DI was finally composed by 67 subtests grouped in eight cognitive domains and it showed good psychometric properties. Normative data were created for five groups taking into account intellectual disability level, age and acquired curricular competence. These data were organized in percentiles in a way that allows the creation of cognitive profiles in the clinical and experimental fields. The TB-DI constitutes a tool of high applicability in the population with intellectual disability. It shows adequate validity and reliability, and it has good psychometric properties. The cognitive profiles obtained by the TB-DI will provide valuable information for the treatment of adult adults with mild and moderate intellectual disability.

  3. Vertical and horizontal variability of PM10 source contributions in Barcelona during SAPUSS

    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 %).

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.

    During the SAPUSS campaign (Solving Aerosol Problems by Using Synergistic Strategies) PM10 samples at twelve hours 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) sulphate (3-4 μg m-3, 11-17 %) and (8) nitrate (4-6 μg m-3, 17-21 %). Three aerosol sources were found 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.

    The aim of the study is to compare, among socio-economically similar areas, the use of medical services, clinical practice and pharmacy costs depending on the how the primary healthcare teams, that provide these services, are organized according to different managemental formulas. Descriptive study of the evaluation of health care services. The population units (basic health areas) attended by the reformed primary health care services in Barcelona were classified into three levels according to the population's socioeconomic status (high, medium or low). For each level, two primary health care teams were selected representing different primary health care providers: "Institut Catala de la Salut"; and others. The influence of both the provision option and the population characteristics on service use, clinical practice and costs of prescription were compared. The services offered by the two provision options differ. However, the use of medical services is related to the socioeconomic characteristics and not to the option for service provision. Whilst there are no relevant differences in clinical practice between the different options, we observed variations among different primary care teams, notably in referrals to specialists and influenza vaccine coverage. The greater source of variation in prescription costs seems to be related to an external confounding factor. Empirical data have not identified relevant differences in the pattern of use, clinical practice, or costs between the different options for service provision within the model of reformed primary care services. Observed variations seem to be associated mainly with the population's characteristics, its pattern of health service use or other external confounding factors.

    The objectives of the present study were to describe smoking prevalence and compare the smoking attributes of adult smokers according to the type of tobacco product consumed. Repeated cross-sectional surveys (2004-2005 and 2011-2012) of a representative sample of the adult (≥16 years) population in Barcelona, Spain, were used to assess self-reported tobacco consumption, smoking attributes, and salivary cotinine concentration. The survey conducted in 2004-2005 included information on 1245 subjects and the survey in 2011-2012 on 1307 individuals. Smoking prevalence decreased over the study period (from 26.6% to 24.1% in self-reported daily smokers). The prevalence of daily smokers who reported the use of manufactured cigarettes declined from 23.7% in 2004-2005 to 17.3% in 2011-2012. The prevalence of roll-your-own cigarette users increased from 0.4% to 3.7%. According to data obtained in 2011-2012, the proportion of self-reported roll-your-own cigarette users was higher among men (19.8% vs. 9.5% of women), participants aged 16-44 years (22.9% vs. 5.8% of participants aged 45-65 years and 4.0% of participants aged ≥65 years), and participants with secondary and university education (17.7% and 18.5% vs. 7.9% of participants with less than primary and primary education). We did not observe differences in cotinine concentrations according to the type of tobacco product consumed. Systematic collection of data on smoking prevalence and smoker attributes from representative samples of the population is necessary for policymakers to develop efficient tobacco control interventions. Considering the increase of roll-your-own cigarette users and the unclear health consequences of their use, policymakers should aim to implement tax policies to equalize the prices of different types of tobacco products.

    Background The impact of immigration on health services utilisation has been analysed by several studies performed in countries with lower levels of immigration than Spain. These studies indicate that health services utilisation is lower among the immigrant population than among the host population and that immigrants tend to use hospital emergency services at the expense of primary care. We aimed to quantify the relative over-utilisation of emergency services in the immigrant population. Methods Emergency visits to Hospital del Mar in Barcelona in 2002 and 2003 were analysed. The country of origin, gender, age, discharge-related circumstances (hospital admission, discharge to home, or death), medical specialty, and variable cost related to medical care were registered. Immigrants were grouped into those from high-income countries (IHIC) and those from low-income countries (ILIC) and the average direct cost was compared by country of origin. A multivariate linear mixed model of direct costs was adjusted by country of origin (classified in five groups) and by the individual variables of age, gender, hospital admission, and death as a cause of discharge. Medical specialty was considered as a random effect. Results With the exception of gynaecological emergency visits, costs resulting from emergency visits by both groups of immigrants were lower than those due to visits by the Spanish-born population. This effect was especially marked for emergency visits by adults. Conclusion Immigrants tend to use the emergency department in preference to other health services. No differences were found between IHIC and ILIC, suggesting that this result was due to the ease of access to emergency services and to lack of knowledge about the country's health system rather than to poor health status resulting from immigrants' socioeconomic position. The use of costs as a variable of complexity represents an opportunistic use of a highly exhaustive registry, which is becoming ever more

    Blastocystis spp. are among the most frequently observed intestinal parasites in humans. Despite the discovery of Blastocystis approximately 100 years ago, limited information is available regarding its pathogenesis, genetic diversity, and available treatment options. The aim of this study was to describe the epidemiological and clinical characteristics of patients with Blastocystis sp. infections diagnosed at Vall d'Hebron University Hospital (Barcelona, Spain). A retrospective observational study was performed which included all adult patients who attended Vall d'Hebron University Hospital from February 2009 to March 2014 that had Blastocystis sp. detected in their stool. Four hundred eighteen patients were included, the median age was 36 (18-86) years and 236 (56.5 %) were men. Regarding patient symptoms, 234 (56 %) patients were completely asymptomatic, 92 (22 %) patients had symptoms, and 92 (22 %) patients had symptoms that could be attributed to other causes. Of the 92 patients with symptoms not attributable to other etiologies except for Blastocystis infection, the most frequent symptoms were diarrhea (61 patients, 66.3 %) and abdominal pain (34 patients, 37 %). Additionally, nine (9.8 %) patients had cutaneous manifestations. Thirty-one (7.4 %) patients received specific treatment for Blastocystis infection. The clinical response of treated patients was varied. Five patients experienced complete resolution of symptoms, 12 patients reported improvement of clinical symptoms, eight patients described no clinical improvement, and information was unavailable for six patients. Blastocystis infection was detected in 418 patients, most of them foreign-born. Although the vast majority of patients were asymptomatic, 22 % of patients had gastrointestinal symptoms or cutaneous manifestations in the absence of other causes. Despite the scarce information available, given the safety of antiparasitic treatment, and the percentage of patients who experienced

    Diagnosis of invasive pulmonary aspergillosis (IPA) is challenging. The objective of the study was to assess the value of microbiological tests to the diagnosis of IPA in the absence of non-specific radiological data. A retrospective study of 23 patients with suspicion of IPA and positivity of some microbiological diagnostic tests was performed. These tests included conventional microbiological culture, detection of Aspergillus galactomannan (GM) antigen and in some patients (1 → 3)-β-D-glucan (BDG) and Aspergillus fumigatus DNA using the LightCycler(®) SeptiFast test. In 10 patients with hematological malignancy, 6 cases were considered 'probable' and 4 'non-classifiable.' In 8 patients with chronic lung disease, 7 cases were classified as 'probable' and 1 as 'proven,' and in 5 patients with prolonged ICU stay (>7 days), there were 2 'proven' cases, 2 'non-classifiable' and 1 putative case. Microbiological culture was positive in 17 cases and 18 Aspergillus spp. were isolated (one mixed culture). A. fumigatus was the most frequent (44.4%) followed by A. tubingensis. The Aspergillus galactomannan (GM) antigen assay was positive in 21 cases (91.3%). The GM antigen and the (1 → 3)-β-D-glucan (BDG) assays were both performed in 12 cases (52.2%), being positive in 9. The SeptiFast test was performed in 7 patients, being positive in 4. In patients with non-classifiable pulmonary aspergillosis and one or more positive microbiological tests, radiological criteria may not be considered a limiting factor for the diagnosis of IPA.

    Case studies of 3 green buildings with LEED certifications that required extensive acoustical retrofit work to become satisfactory work environments for their intended user groups will be used to define areas where green building design concepts and acoustical design concepts require reconciliation. Case study 1 is an office and conference center for a city environmental education agency. Large open spaces intended to collect daylight through clerestory windows provided large, reverberant volumes with few acoustic finishes that rendered them unsuitable as open office space and a conference room/auditorium. Case Study 2 describes one of the first gold LEED buildings in the southeast whose primary design concepts were so narrowly focused on thermal and lighting issues that they often worked directly against basic acoustical requirements resulting in sound levels of NC 50-55 in classrooms and faculty offices, crosstalk between classrooms and poor room acoustics. Case study 3 is an environmental education and conference center with open public areas, very high ceilings, and all reflective surfaces made from wood and other environmentally friendly materials that result in excessive loudness when the building is used by the numbers of people which it was intended to serve.

    EPA Pesticide Factsheets

    EPA announced the release of the final report, Nanomaterial Case Study: Nanoscale Silver in Disinfectant Spray. This report represents a case study of engineered nanoscale silver (nano-Ag), focusing on the specific example of nano-Ag as possibly used in disinfectant sprays. This case study is organized around the comprehensive environmental assessment (CEA) framework, which structures available information pertaining to the product life cycle, environmental transport and fate, exposure-dose in receptors (i.e., humans, ecological populations, and the environment), and potential impacts in these receptors. The document does not draw conclusions about potential risks. Instead, it is intended to be used as part of a process to identify what is known and unknown about nano-Ag in a selected application. In turn, the external review draft of the document provided a starting point to identify and prioritize possible research directions to support future assessments of nanomaterials. The information presented in the case study and the questions raised in this document are a foundation for a process to determine priorities among various research topics and directions. After that process has been completed, a final chapter will be added to this document to summarize highlights from preceding chapters and the major research issues that have emerged.
