Abstract

A screening investigation was carried out in a large industry in the Copenhagen region and 1,472 of the employees were offered examination of blood cholesterol and measurement of blood pressure. At this examination the employees completed a one-page questionnaire about other cardiovascular risk factors. 45% of those invited participated in the investigation, the poorest participation was among women and the greatest among the male officials. On account of the limited number of female employees, the majority of results were only calculated for men. Over 1/3 of these had hypercholesteremia (greater than or equal to 7.0 mmol/l) and nearly 1/3 had, simultaneously, at least two cardiovascular risk factors in addition to age and male sex. Extensive occupational investigations under the auspices of WHO have demonstrated that energetic intervention at the place of work aimed at the cardiovascular risk factors can reduce the risk of development of coronary heart disease and death within a six-year follow-up period. It is therefore emphasized that similar interventions are very necessary also in Denmark.

Abstract

Experimental studies compared the particle size distribution, mineralogy, thermal differentials and solubility of P2O5 and fluorine in 2% citric acid of phosphate ores from Sechura in Peru with those from Idaho, central and northern Florida, Tunisia and Morocco. The results showed that Bayovar phosphate compares well with products offered by market leaders. Solubility was 92.66% of P2O5 at the third extraction from rock containing 4.8% phosphate, fractionally higher than the 92.22% extraction from Tunisian phosphate rock, while the 72% F extraction gave an end fluorine content 36% lower (1.98 kg/t rock, compared with 3.11 kg/t Tunisian rock). The inferior mechanical characteristics should favour low concentration costs and the negative incidence of contaminants such as Cd and Pb is also an advantage. Bayovar represents 2.5% of world phosphate reserves and 16% of circum-Pacific reserves., Experimental studies compared the particle size distribution, mineralogy, thermal differentials and solubility of P2O5 and fluorine in 2% citric acid of phosphate ores from Sechura in Peru with those from Idaho, central and northern Florida, Tunisia and Morocco.

Abstract

Aim: We aimed to investigate the prognostic value and reveal the role of a novel method speckle tracking echocardiography for predicting adverse cardiovascular events in STEMI patients undergoing successful primary percutaneous intervention (PCI). Methods: We included 117 patients who admitted to University Cardiology Clinic with STEMI and underwent successful PCI between June 2011 and January 2012. After PCI, in the first three days (baseline) and at the first month after discharge (control), echocardiographic evaluations of patients were carried out. The relationship between cardiac adverse events that occurred during the six-month follow-up and echocardiographic parameters were evaluated. Patients were divided into two groups according to development of adverse event (a composite of revascularization, reinfarction and hospitalization for heart failure) and comparisons between groups were made. Results: When we compare the baseline strain values of patients included in the study, the baseline average global longitudinal strain (GLS) of event group (n=20) was -12,10 ± 2,59; the baseline average GLS of event free group (n=97) was -14,46 ± 3,65. In the group with event, we determined statistically significant lower baseline GLS values. In terms of baseline circumferential strain (CS) and radial strain (RS) values, there was no statistically significant difference between the two groups. In the roc analysis, when we use the threshold values below -12,9 for the baseline GLS, we detected that baseline GLS predicted the development of adverse events with % 75 sensitivity and % 70 specificity. While there was no change in control GLS values from the baseline in the event group at first month echocardiography, in the event free group, statistically significant higher and improved strain values were observed. According to these results, increased strain values at the first month were associated with better prognosis. In terms of CS and RS values, there was no statistically significant difference between baseline and control in both groups. Conclusion: Our study revealed that strain analysis with speckle tracking echocardiography is a new echocardiographic method which can be used to determine the prognosis of patients with STEMI.

220. Fractional flow reserve to decide between percutaneous transluminal coronary angioplasty or coronary artery bypass grafting in patients with angiographically multivessel disease: a tailored approach

Author

Botman, C.-J., Bech, J. W., De Bruyne, B., Bonnier, H., Bartunek, J., Koolen, J., Michels, R., and Pijls, N.

Abstract

HintergrundEs ist unklar, ob eine vollständige Revaskularisation mittels Bypasschirurgie (CABG) einer auf die Zielläsion beschränkten perkutanen transluminalen Koronarangioplastie (PTCA) überlegen ist. Die Bestimmung der fraktionalen Flussreserve (FFR) mittels koronarer Druckmessung stellt einen verlässlichen Indikator dar, ob eine Koronarstenose hämodynamisch relevant ist und daher als Zielläsion angesehen werden muss. Das Ziel dieser Studie war daher, eine ausschließliche PTCA von Zielläsionen (FFR kleiner als 0,75) mit einer CABG aller stenosierten Gefäße zu vergleichen. MethodenBei 130 Patienten, bei denen eine CABG geplant war, wurde die FFR von 322 angiographisch relevant stenosierten Koronararterien bestimmt. Sofern die FFR von 3 oder 2 Gefäßen (einschließlich der proximale LAD) kleiner als 0,75 war, wurde eine CABG vorgenommen. Die Kardiologen und Chirurgen waren für diese Ergebnisse geblindet (CABG-Gruppe). Wurden nur 1 oder 2 Gefäße als Zielläsion (ohne proximale LAD) identifiziert, wurde eine PTCA ausschließlich dieser Läsionen vorgenommen (PTCA-Gruppe). ErgebnisseDie 2-Jahres-Verlaufsuntersuchungen sind bis dato bei 75 Patienten der CABG-Gruppe und bei 55 der PTCA-Gruppe abgeschlossen. Nach zwei Jahren bestanden keine Unterschiede hinsichtlich der unerwünschten Ereignisse (ereignisfreies Überleben in 84,1 % der CABG-Gruppe und 83,9 % der PTCA-Gruppe) und der Freiheit von Angina pectoris (85 % in der CABG-Gruppe, 82 % in der PTCA-Gruppe). SchlussfolgerungDie fraktionale Flussreserve ist ein hervorragendes Instrument zur Identifizierung von hämodynamisch wirksamen Stenosen bei koronarer Dreigefäßerkrankung. Nach der funktionellen Bedeutung können Patienten mit angiographisch vergleichbaren Befunden in zwei Gruppen eingeteilt werden: Patienten mit einer oder zwei Zielläsionen (ohne proximale LAD; PTCA-Gruppe) und Patienten mit 2 oder mehr Zielläsionen (einschließlich LAD; CABG group). Eine PTCA ausschließlich der mittels Bestimmung der FFR identifizierten Zielläsionen führte in einem zweijährigen Beobachtungs-zeitraum zu ähnlichen klinischen Ergebnissen wie eine vollständige operative Revaskularisation. BackgroundIn multivessel disease, it is controversial whether complete revascularization by bypass surgery (CABG) is superior to PTCA of the culprit lesions only. Fractional flow reserve (FFR), calculated from coronary pressure measurement, is a reliable index to identify whether a stenosis is culprit (i.e., functionally significant). AimTo compare selective PTCA of culprit lesions only (FFR less than 0.75) to CABG of all stenoses. MethodsIn 130 patients, referred for CABG, FFR was determined in 322 coronary arteries which were all considered for bypass grafting based on angiographic information only. If FFR was less than 0.75 in 3 or 2 stenoses including those located in the proximal left anterior descending coronary artery (LAD), CABG was performed on all vessels for which bypass grafting was considered to be necessary as judged angiographically by the surgeon and cardiologist who were blinded to the FFR results (CABG group). If only 1 or 2 lesions not including proximal LAD were culprit, PTCA of those lesions only was performed (PTCA group). ResultsSo far a 2 year follow-up has been completed in 75 patients assigned to CABG and 55 to PTCA. After 2 years, no differences were seen in adverse events (event-free survival 84.1 % in the CABG group and 83.9 % in the PTCA group) and a similar number of patients were free from angina (85 % in the CABG group and 82 % in the PTCA group). ConclusionIn multivessel disease, coronary pressure measurement is an excellent tool to identify the culprit lesion(s) by FFR < 0.75. In this way, patients with otherwise similar angiographic characteristics can be stratified into 2 groups, according to the functional extent of disease: patients with one or 2 culprit lesions excluding proximal LAD (PTCA group) and patients with 2 including LAD or more culprit lesions (CABG group). Within the group of patients with angiographically identified multivessel disease, PTCA of culprit lesion(s) only, as discriminated by an FFR of less than 0.75, yields a similar 2-year outcome as complete revascularization by bypass surgery.

221. Low temperature annealing of cold-drawn pearlitic steel wire

Author

Zhang, X, Bech, J I, and Hansen, N

Abstract

Cold-drawn pearlitic steel wires are nanostructured and the flow stress at room temperature can reach values above 6 GPa. A typical characteristic of the nanostructured metals, is the low ductility and thermal stability. In order to optimize both the processing and application of the wires, the thermal behaviour is of interest. This has been studied by annealing the wires for 1h at temperatures from ambient temperature to 300 degC (573 K). It is expected that a raising temperature may lead to structural changes and a reduction in strength. The change in strength is however not expected to be large. For this reason we have applied a very precise technique to measure the tensile properties of the wires from a strain of 10-4 to the maximum strain of about 1-2%. The structural changes have also been followed to estimate and relate strength changes to changes in structural parameters and morphology.

Abstract

Purpose: Although delayed-enhancement magnetic resonance imaging (DEMRI) is essential for diagnosis of cardiac sarcoidosis (CS), the test was not available when pacemaker was implamted. Recently, MR-conditional pacemaker has become avilable and we hypothesized that this device would be useful for diagnosis and management of CS. The aim of this study was to assess the diagnostic ability of MR-conditional pacemaker about CS in patients with advanced A-V nodal block (AAVB). Methods: Twenty-seven AAVB patients (14 men, 13 women; mean age, 69 ± 11 years) who were implanted MR-conditional pacemaker were studied. DEMRI was performed 6 weeks after implantation of permanent pacemaker. In patients with positive for DE, additional examinations like echocardiography, radioisotope imaging, biopsy, and coronary computed-tomography were performed due to confirm the diagnosis of CS and exclude coronary artery disease. Results: DE was observed in 12 patients (44 %). Out of 12 patients, 2 patients were excluded for having prior myocardial infarction. Seven of 10 (70 %) patients were diagnosed of CS by the consensus criteria. Compared with non-CS group, CS group had significantly lower age (61 ± 12 years vs. 72 ± 9 years p = 0.017). There was no significant difference about sex, angiotensin-converting enzyme, brain natriuretic peptide, and left ventricular ejection fraction between 2 groups. Six patients had started corticosteroid therapy and 5 patients (83%) recovered A-V nodal conduction. Conclusion: MR-conditional pacemaker was useful for diagnosis and management of patients with AAVB caused by CS. Figure Cardiac MRI in patient with AV block

Abstract

Clinical PET acquisitions of the heart suffer from artefacts and drops in image quality due to the poor spatial resolution of the PET system. Moreover, cardiac PET images are further degraded by the blur caused by the breathing and beating motions, thus hampering diagnosis and evaluation of myocardial pathologies. Anatomy-enhanced PET reconstruction, using a high-resolution CT, has proven useful in brain imaging. In cardiac datasets however, due to the motion artefacts, the application of any restoring technique on datasets affected by motion blur needs to be preceded by the validation of the proposed method on realistic static datasets. In this work, the validation is performed using static cardiac ex vivo datasets obtained from a number of sacrificed sheep, scanned on a clinical PET/CT scanner. The aim of this work is to assess the effectiveness of reconstructions of the acquired datasets with different CT-based anatomical priors, in comparison to reconstructions currently applied in clinical practise. The gold standard to which all reconstructions are compared consists of images of the same hearts scanned on a small-animal PET scanner, whose high spatial resolution allows for almost artefact-free images. Encouraging results were obtained so far, with improvements in volume delineation and uniformity of activity values when anatomical information was used. Fig 1 shows the gold standard image (left) compared to a regular clinical reconstruction (middle) and to a reconstruction using the high-resolution CT as anatomical information (right). Figure

Abstract

Introduction: Among patients with unexplained dyspnea, left ventricular (LV) filling pressures (LVFP) is commonly estimated non-invasively by the E/e' ratio using Doppler echocardiography. However the accuracy of E/e' is controversial. We evaluated the correlation of E/e' ratio with invasively measured LVFP and of change in E/e' (ΔE/e') with change in LVFP. Methods: Supine and upright transthoracic echocardiography was performed in patients with unexplained dyspnea undergoing right heart catheterization. Patients with significant valvular disease and reduced LV ejection fraction (LVEF < 50%) were excluded. Pulmonary artery wedge pressure (PAWP) was used as the invasive indicator of LVFP. The mean of septal and lateral e' velocities was used for the calculation of E/e' ratio. Results: We studied 98 subjects with a mean age of 52 ± 20 years (69% of female gender). The supine E/e' and PAWP were 9.2 ± 3.2 and 12.1 ± 4.9 mmHg (range: 4-27 mmHg) respectively and were modestly correlated (r=0.38; p<0.001). With position change (supine to upright), ΔPAWP was -5.1 ± 4.3 mmHg and ΔE/e' was 0.17 ± 2.6, with no significant association between these two measures (r=0.003; p=0.98). Both E-wave (80 ± 22 to 65 ± 22 cm/s) and mean average e' (10.2 ± 3.6 to 7.3 ± 2.0 cm/s) decreased with the upright position. The ΔPAWP was correlated with ΔE-wave velocity (r=0.33; p=0.01), but not with Δe' (r=0.14; p=0.26). Conclusions: In patients with unexplained dyspnea and a preserved LVEF, E/e' is modestly, though significantly, correlated with PAWP. ΔE/e' is not correlated with ΔPAWP, partially related to the preload sensitivity of e'.

Abstract

Data acquired by a dense seismic network deployed in the Cerdanya basin (Eastern Pyrenees) is used to track the temporal and spatial evolution of meteorological events such as rainfall episodes or thunderstorms. Comparing seismic and meteorological data, we show that for frequencies above 40 Hz, the dominant source of seismic noise is rainfall and hence the amplitude of the seismic data can be used as a proxy of rainfall. The interstation distance of 1.5 km provides an unprecedented spatial resolution of the evolution of rainfall episodes along the basin. Two specific episodes, one dominated by stratiform rain and the second one dominated by convective rain, are analyzed in detail, using high resolution disdrometer data from a meteorological site near one of the seismic instruments. Seismic amplitude variations follow a similar evolution to radar reflectivity values, but in some stratiform precipitation cases, it differs from the radar-derived precipitation estimates in this region of abrupt topography, where radar may suffer antenna beam blockage. Hence, we demonstrate the added value of seismic data to complement other sources of information such as rain-gauge or weather radar observations to describe the evolution of ground-level rainfall fields at high spatial and temporal resolution. The seismic power and the rainfall intensity have an exponential relationship and the periods with larger seismic power are coincident. The time intervals with rain drops diameters exceeding 3.5 mm do not result in increased seismic amplitudes, suggesting that there is a threshold value from which seismic data are no longer proportional to the size of the drops. Thunderstorms can be identified by the recording of the sonic waves generated by thunders, with. Single thunders detected to distances of a few tens of kilometers. As the propagation of these acoustic waves is expected to be strongly affected by parameters as air humidity, temperature variations or wind, the seismic data could provide an excellent tool to investigate atmospheric properties variations during thunderstorms.

Abstract

In this paper a study of the radio propagation environment of electromagnetic waves prevailing in the lower troposphere of the Western Mediterranean basin is presented. Deviations from atmospheric average or standard radio propagation conditions (anomalous propagation or AP) can affect significantly the quality of weather radar observations and other telecommunication systems. This is particularly important when ducting or superrefraction is present and spurious echoes resulting from the interaction of the beam with the ground or sea surface may appear. These AP conditions occur mainly when temperature inversions or strong moisture gradients are present. The period covered in this study ranges from 1999 to 2008 and conditions were derived from the Weather Research and Forecasting (WRF) modeling system, using the Japanese 25-year Reanalysis (JRA25) dataset as initial and boundary data. From the WRF model, we use the temperature, moisture, and pressure fields with a grid length of 30-km horizontal resolution and 250 m vertical resolution to compute several indices such as the Vertical Refractivity Gradient, Vertical Modified Refractivity Gradient and a Ducting Index. Results obtained show that on the Western Mediterranean coast the most favorable conditions for superrefraction are found in summer, while the most affected areas are the Gulf of Valencia, the Strait of Gibraltar and the Northern Gulf of Lion. Additionally, a comparison with radiosonde data recorded in Barcelona (NE Spain) is also performed indicating an overall agreement between model and observational data despite a tendency to decrease subrefractive events by the WRF model.

Abstract

Purpose: Cardiac deconditioning due to immobilization is a risk factor for cardiovascular disease. The physiology of cardiac adaptation to deconditioning has not been fully elucidated. The purpose of the present study was to assess the effects of 21-days of strict head-down (-6 degrees) bed-rest (BR) deconditioning on left ventricular (LV) dimensions and mass measured by MRI. Methods: Ten healthy men (mean age 32±6) were enrolled; the experiment was conducted at DLR (Koln, Germany) as part of the European Space Agency BR studies. Steady-state free precession MRI images (7mm thickness, no gap, no overlap) were obtained (Symphony 1.5T, Siemens) in a stack of short-axis views from LV base to LV apex, before (PRE), at the end of BR (HDT20), and four days after the BR conclusion (POST). Endocardial and epicardial semi-automated contouring was performed using freely available software (Segment). Results: At HDT20, significant reductions in LV mass (16%), end-diastolic (26%) and end-systolic (27%) volumes and stroke volume (27%) were observed, while ejection fraction did not change. These changes were accompanied by a measured decrease (14%) in plasma and blood volume (by gas-rebreathing technique), as well as by a significant reduction (14%) in VO2max aerobic power, measured using a graded cycle ergometer test protocol to volitional fatigue, at one day after the BR conclusion, while expiratory exchange ratio did not change. At POST, LV volumes were restored, while LV mass was still trending towards control values. Conclusions: Cardiac adaptation to deconditioning affected LV mass and dimensions, as a combined result of LV remodeling and fluids loss, accompanied by worsening in aerobic power. This should be taken into account in patients with cardiovascular diseases, when immobilized in bed, to proper adjust the therapy, or to define appropriate physical exercises when possible, in order to avoid further complications.   Cardiac MRI parameters PREHDT20POSTLV mass (g)121±6102±11*114±16End-diastolic volume (ml)119±2590±14*118±25End-systolic volume (ml)42±831±8*45±14Stroke volume (ml)76±2259±11*73±15Ejection fraction (%)64±665±762±7 *: p<.01 vs PRE (one-way Anova for paired data and Tukey test)

Abstract

Pulmonary vascular dysfunction is claimed to be a contributor to the development of pulmonary hypertension (PH). Impaired systemic vascular reactivity is one of the essential factors in the pathogenesis of cardiovascular disease. The aim of the investigation was to study whether there is any association between systemic vascular function and pulmonary artery pressure (PAP) in patients who have associated causes for PH development, such as coronary heart disease (CHD) and chronic obstructive pulmonary disease (COPD). Methods: The brachial artery vasodilator responses were measured by the ultrasound technique in twenty patients with mild to moderate COPD (group I) and twenty age–matched and COPD stage-matched patients who had past history of myocardial infarction (NYHA II) (group II).Conventional echocardiographic variables were measured in the said patients too. Results: Both flow-mediated dilatation (FMD) and nitrate-mediated dilatation (NMD) were significantly lower, and PAP was significantly higher in the group II patients compared to the same parameters of group I patients. NMD was inversely correlated with PAP (r=-0.7, p=0.02) in group I patients. There was no interrelation between FMD and PAP in patients from group I. Neither FMD nor NMD were correlated with PAP in group II patients. A significant positive correlation between PAP and left ventricular mass index (r=0.8, p=0.003) was revealed in the said patients as well. Conclusions: Attenuated vasodilator response of brachial artery to nitroglycerine is associated with PAP elevation in COPD patients. PH is closely related to cardiac remodeling in COPD patients in whom CHD developed. These data suggest different "stages" of vascular and cardiac remodeling in patients with COPD alone and in coexistence with CHD. The obtained data can be useful in the selection of treatment as regards these patient categories.

Abstract

A study was conducted in Catalonia (NE Spain) to determine the baseline levels and the polluted contents of Ba, Cd, Cr, Cu, Ni, Pb, V andZn (aqua regia-extractable) in soils of an agroindustrial area near Barcelona. The samples analyzed proceeded from two soil surveys. 268 samples belonged to 67 representative, and slightly disturbed, soil profiles sampled during a previous soil survey, and 95 superficial samples were taken near a composting plant (heavily disturbed and presumably polluted). Probability plots were used to establish the reference (or background) levels and a literature comparison was made to check the validity of the background ranges established. The raw data sets and the uncontaminated resulting populations were studied by means of frequency histograms and of statistical tests in order to verify the general assumption, which states that trace element distributions in soils follow the log-normal law. The results showed that the studied elements were distributed in these soils following the log-normal law and that the established reference values were in agreement with those reported in the literature.

Abstract

Statins improve cardiovascular survival in both nondia-betic and diabetic patients, but diabetic patients benefit more, in both primary and secondary prevention. Statins seem to have multiple effects beyond cholesterol lowering, that is, pleiotropic effects that may include changes in renal function. This study tests the hypothesis that acute treatment with atorvastatin may change glomerular filtration rate, tubular function, vasoactive hormones, blood pressure, and pulse rate in patients with type 2 diabetes. In an acute, randomized, placebo-controlled, double-blinded, crossover trial, the effects of atorvastatin on renal function, vasoactive hormones, blood pressure, and pulse rate are measured in 21 patients with type 2 diabetes. Patients are randomized to either 2 doses of atorvastatin 80 mg or placebo before 2 different study days. Treatment with atorvastatin induces a significant reduction in fractional sodium excretion compared with placebo, and sodium clearance tends to be reduced. No significant differences in glomerular filtration rate, albumin/creatinine ratio, vasoactive hormones, and blood pressure by acute treatment with atorvastatin are found in diabetic patients. Acute treatment with atorvastatin reduces renal fractional sodium excretion in patients with type 2 diabetes. No changes are measured in glomerular filtration rate, albumin/creatinine ratio, vasoactive hormones, and blood pressure. [ABSTRACT FROM AUTHOR]

Abstract

Abstract: Hail is one of the most fearsome meteorological phenomena for agricultural areas. The harvest of the whole year can be destroyed in only a few minutes. A pilot project to characterise hail events and identify hail with the help of radar observations is described in this paper. This pilot project was carried out in Terres de Ponent, an area of about 200,000 ha in Lleida (Catalonia), in the NE of the Iberian Peninsula. The aim of the project was to characterise hail events, directly by radiosounding data and radar images, and indirectly by the evaluation of the radiosonde forecasted by the Numerical Weather Prediction (NWP) Mesoscale Atmospheric Simulation System (MASS) and several instability indices. In the first stage of the project several instability indices were calculated during the 5 months of the campaign and a comparison of these indices with those obtained with radiosounding data from Barcelona and Zaragoza was performed. An operative image of the probability of hail distribution in Catalonia (every 6 min, hourly and daily) was also made using the Waldvogel method for its detection. As a starting point, an empirical fit of POH (probability of hail) obtained recently in the Netherlands (POH=0.319+0.133·ΔH, where ΔH is the difference between the 45 dBZ echo top height from radar image and the isozero forecast). Complementary to this, to detect the hail at the beginning of spring, the process was repeated with the 35 dBZ echo top. In a second stage of the project, the calculated POH was compared with the hail events measured by 171 hailpads of the observational network of the Agrupació de Defensa Vegetal (ADV) of Terres de Ponent and a new fit of the POH formula was obtained. It was also the aim of this second stage to validate the forecasted radiosoundings by the NWP MASS model in Lleida and Barcelona. Finally, a comparison between the radiosounding data from Barcelona, Lleida and Zaragoza was made to verify which radiosounding (Barcelona or Zaragoza) is more representative of the Lleida area.

Abstract

The final dilution of urine is regulated via aquaporin-2 water channels in the distal part of the nephron. It is unclear whether urine dilution ability in autosomal dominant polycystic kidney disease patients (ADPKD patients) differs from other patients with similar degree of impaired renal function (non-ADPKD patients). The purpose of this case control study was to measure urine dilution ability in ADPKD patients compared to non-ADPKD patients and healthy controls. Methods. Eighteen ADPKD, 16 non-ADPKD patients (both with chronic kidney disease, stage I-IV), and 18 healthy controls received an oral water load of 20 ml/kg body weight. Urine was collected in 7 consecutive periods. We measured free water clearance (CH2O), urine osmolality, urine output, fractional excretion of sodium, urine aquaporin2 (u-AQP2), and urine epithelial sodium channel (u-ENaC). Blood samples were drawn four times (at baseline, 2 h, 4 h, and 6 hours after the water load) for analyses of plasma osmolality, vasopressin, renin, angiotensin II, and aldosterone. Brachial and central blood pressure was measured regularly during the test. Results. The three groups were age and gender matched, and the patient groups had similar renal function. One hour after water load, the ADPKD patients had an increased CH2O compared to non-ADPKD patients (2.97 ± 2.42 ml/min in ADPKD patients vs. 1.31 ± 1.50 ml/min in non-ADPKD patients, p 0.029). The reduction in u-AQP2 and u-ENaC occurred earlier in ADPKD than in non-ADPKD patients. Plasma concentrations of vasopressin, renin, angiotensin II, and aldosterone and blood pressure measurements did not show any differences that could explain the deviation in urine dilution capacity between the patient groups. Conclusions. ADPKD patients had a higher CH2O than non-ADPKD patients after an oral water load, and u-AQP2 and u-ENaC were more rapidly reduced than in non-ADPKD patients. Thus, urine-diluting capacity may be better preserved in ADPKD patients than in non-ADPKD patients. [ABSTRACT FROM AUTHOR]

Abstract

16 Pág., Mining activity is one of the main sources to pollute soil, water and plants. An analysis of soil and plant samples around the Atrevida mining area in Catalonia (NE Spain) was preformed to determine potentially harmful elements (PHEs). Soil and plant samples were taken at eight locations around the mining area. The topsoil (0-15 cm) samples were analysed for physico-chemical properties by standard methods, by ICP-MS for Cd, Co, Cr, Cu, Fe, Ni, Pb and Zn, and were microwave-digested. Plant, root and shoot samples were digested separately, and heavy metals were analysed by AAS. Translocation factor (TF), biological concentration factor (BCF) and biological accumulation factor (BAF) were determined to assess the tolerance strategies developed by native species and to evaluate their potential for phytoremediation purposes. Soil pH was generally acid (5.48-6.72), with high soil organic matter (SOM) content and a sandy loamy or loamy texture. According to the agricultural soil values in southern Europe, our PHEs concentrations exceeded the toxicity thresholds. The highest root content of the most studied PHEs appeared in Thymus vulgaris L. and Festuca ovina L., while Biscutella laevigata L. accumulated more PHEs in shoots. The TF values were > 1 in B. laevigata L., but BAF obtained, Open Access funding provided thanks to the CRUE-CSIC agreement with Springer Nature. This study was supported by projects “Potencialidad de la reutilización de agua de la EDAR de Pinedo para uso agrícola OTR2016-16953INVES,” and “Estudio multidisciplinar para evaluar la presencia de posibles contaminantes y su trazabilidad en aguas regeneradas y en el medio costero marítimo OTR2016-16953INVES” funded by Conselleria de Agricultura, Medio Ambiente, Cambio Climático y Desarrollo Rural de la GENERALITAT VALENCIANA.

Abstract

During Intensive Observation Period 15a (20 October 2012) of the first Special Observation Period of the Hydrological cycle in the Mediterranean Experiment, northeastern Spain experienced heavy precipitation (130 mm in 24 h) associated with a retrograde regeneration mesoscale convective system (MCS) developing in the exit region of the Ebro River Valley (ERV). The life cycle of the MCS that brought intense hourly rainfall (34 mm) from the foothills of the Iberian Plateau to the central Pyrenees, as well as the detailed structure of the moist marine flow upstream, were analysed using a combination of ground-based, airborne and space-borne observations as well as model analyses. Over the Balearic Sea, the southwesterlies along the northeastern flank of a surface low converged with southeasterlies from North Africa, creating a near-surface moisture tongue in the region of the Balearic Islands, and a southeast-northwest oriented convergence line within a cloud cluster advecting from northern Africa. Airborne lidar measurements, acquired upstream of the ERV, evidenced water vapour mixing ratios in excess of 15 g kg−1 in the marine atmospheric boundary layer. In the mid-level (700 hPa), the presence of an elevated moisture plume from tropical Africa contributed about one third to the large moisture content present over the western Mediterranean Sea. In this moist environment, the MCS was initiated over the orography of the northeastern tip of the Iberian plateau, due to the combined influence of the approaching convergence line ahead of the surface low and the convergence resulting from weak northwesterlies channelled in the ERV and the easterlies impinging on the coastal range. After the initiation phase, the MCS further developed over the foothills of the Iberian Plateau and moved into the ERV and along the southern flank of the Pyrenees, thanks to the penetration of the warm and moist maritime southeasterly flow through the narrow gap between the northeastern part of the Iberian Plateau and the Catalan coastal range.

Abstract

Phosphogypsum (PG) is a waste product of the phosphoric acid production process and contains, generally, high activity concentrations of uranium series radionuclides. This study is a contribution towards a risk assessment in areas affected by phosphate industry in SW Spain, integrating information from soil physicochemical characteristics, total and soluble potentially toxic elements (Zn, Pb, Cd, Cu, As and Fe), mineralogical composition and ecotoxicological evaluation. The applied bioassays confirmed the soil toxicity categorisation and then, it is highly recommended to complement the results from environmental chemistry with results from bioassays, in order to provide a more complete and relevant information on the bioavailability of contaminants and to characterise the risk of contaminated areas.

Abstract

The total, water soluble and extractable concentrations with EDTA of As from topsoils from the Amblés Valley (Ávila, Spain) were determined. The geochemical baseline concentrations of total As were established, and the relationships between the concentration of the different As forms and soil properties were investigated. Total As content in soils was related with parent material, whereas anthropogenic activities affected its mobility. Iron, aluminium, clay content, soil organic matter and soil pH were the main controlling factors for As soil concentrations. The geochemical baseline concentrations obtained (mg kg − 1 ) were 7.3–35 in soils on granite parent material and 2.2–6.8 in soils on alluvium–colluvium parent material for total As. The baseline concentration values for the water soluble and EDTA extractable As forms were also established. For water soluble As, the baseline concentrations (mg kg − 1 ) were 0.06 for natural soils and 0.37 for agricultural and industrial soils, respectively, and the baseline concentrations for As extractable with EDTA were 0.39 mg kg − 1 .

Abstract

Environmental pollution control is one of the most important goals in pollution risk assessment today. The aim of this study is to conduct a retrospective view of the evolution of matter particulate (PM10) and the heavy metals (Cd, Ni and Pb) at different localities (Alcora, Castellón and Onda) in the Spanish cluster ceramic in a period between January 2007 and December 2011. The study area is in the province of Castellón. This province is a strategic area in the framework of European Union Pollution control. Approximately 80% of European ceramic tiles and ceramic frits manufacturers are concentrated in two areas, forming the so-called "ceramic clusters"; one is in Modena (Italy) and the other in Castellón (Spain). In these kind of areas, there are a lot of pollutants from this industry that represent an important contribution to soil contamination so it is necessary to control their air quality. In these areas atmospheric particles are deposited in the ground through both dry and wet deposition. Soil is a major sink for heavy metals released into the environment. For this purpose the levels of PM10 in ambient air and the corresponding annual and seasonal trend were calculated. The results of the study show that the PM10 and heavy metal concentrations are below the limit values recommended by European Union Legislation for the protection of human health and ecosystems in the study period. There is an important reduction of them from 2009 in all control stations due to economic crisis and subsequent decrease of industrial activity. The atmospheric seasonal tendency of pollutant concentrations is marked by the rate of industrial activity and additionally by the temperature. Complementarily, a comparative study of heavy metal levels in soils was performed in this area. Soils with low pollution by Ni and Pb were detected, while different pollution by Cd was found depending on the sampling site. Although there is an evident reduction of PM10 and heavy metal levels, the results show that these pollutants have been accumulated in the soil close to emission sources. [ABSTRACT FROM AUTHOR]

Abstract: The effect of marble waste and pig slurry on the growth of native vegetation and heavy metal mobility in an abandoned Pb-Zn-Cd tailing pond (southeast Spain) has been investigated. Different treatments were carried out in four plots, (1) pig slurry, (2) marble waste, (3) marble waste+pig slurry, and (4) control. Plant cover, richness, biodiversity, metal in plant tissues, soil physicochemical properties and water and DTPA extractable metal concentrations of bare and rhizosphere soils were analyzed after one year from the application of the treatments. The pond materials contain large amounts of Fe-oxyhydroxides, sulphates, and heavy metals. Before the application of amendments, soil remained bare and organic matter content was very low. After applications, a native vegetation cover (25–30%) with the highest biodiversity (H=1.1–1.3) and a richness of 10 was reached in the plots amended with pig slurry. The establishment and development of vegetation improved soil quality and decreased the metal availability, even more efficiently than the direct effect of the amendments. Among indigenous vegetation, Piptatherum miliaceum (L.) Cosson showed the characteristics of Pb phytostabilizer plant species. This study confirms the effectiveness of a vegetation cover for the persistence of the reclamation processes in bare mine soils under Mediterranean semiarid conditions. [Copyright &y& Elsevier]

Abstract

Abstract: Plants to be used in phytoremediation of mine spoil soils in the Mediterranean area need multi-stress resistance not only including metal tolerance, but also tolerance to seasonal drought and heat. Smilax aspera L., an evergreen climber, is frequently found on metal polluted soils under Mediterranean climate. Here the accumulation of selected alkaline earth elements (Ba, Ca, Sr) and heavy metals (Pb, Zn, Cd) in leaves of S. aspera growing on and off spoils of an ancient galena/barite mine, located in NE Spain, was analyzed. S. aspera was found to efficiently restrict metal accumulation in the leaves. This indicates low risk for food chain transfer of polluting metals when S. aspera is used in phytostabilization technologies. [Copyright &y& Elsevier]

Abstract

Abstract: Particulate air pollutants from industrial emissions and natural resource exploitation represent an important contribution to soil contamination. These atmospheric particles, usually settleable particulate (which settle by gravity) are deposited on the ground through both dry and wet depositions. The most direct consequences of air pollutants on the ground are acidification and salinization, not to mention the pollution that can cause heavy metals as components of suspended particulate matter. A study of heavy metal concentrations in the settleable particulate matter in two locations has been performed with the aim to assess the influence of air pollution on soil composition. These two locations, (Almazora and Vila-real) are within the ceramic cluster of Castellón (Spain) and they have high industrial density. Settleable particulate samples were collected with a PS Standard British captor (MCV-PS2) for monthly periods between January 2007 and December 2009. Heavy metals (Cd, Pb, Ni, Sb and Bi) have been analysed in the soluble fraction of settleable air particles using ICP-MS. The results related to the heavy metal concentration over the observation period show a high seasonal variability for heavy metal content in settleable particulate and a strong dependence on the rainfall in the study area. The maximum values of heavy metals were obtained in spring or autumn coinciding with the highest rainfall, while the lowest values were generally obtained during periods of low rainfall (summer).The annual variation of the results obtained in both populations shows a decline over the study period in the concentrations of heavy metals analysed. This fact is associated with the steady implementation of corrective measures in the main industrial enterprises in the area based on the treatment of mineral raw materials. Moreover, this decline is, in turn, a lower quantity of heavy metals entering the soil, which results in the presence of soils with low contamination by heavy metals in the sampling area.

Abstract

Abstract: The study of metal contents in industrial, agricultural or/and polluted soils compared with natural or unpolluted soils is currently necessary to obtain reference values and to assess soil contamination. Nonetheless, very few works published appear in international journals on elements like Se, Li and Sr in Spanish soils. This study determines the total levels of Se, Li, Sr, As, Cd, Co, Cr, Cu, Ni, Pb, V, Zn, Fe, Mn and Ba in 14 natural (unpolluted) soils (Gypsisols, Leptosols, Arenosols and Acrisols), 14 agricultural soils (Anthrosols, Fluvisols and Luvisols), and 4 industrial–urban affected-surface soil horizons (Anthrosols and Fluvisols) of Eastern Spain. The geochemical baseline concentrations (GBC) and reference values (RV) have been established, and the relationships among elements and also between soil properties and elemental concentrations have been analysed. The RV obtained in this study were (mgkg−1): Se 2.68, Li 115, Sr 298, Cd 0.97, Co 35, Cr 217, Cu 46, Ni 50, Pb 137, V 120, Zn 246, Fe 124,472, Mn 2691, and Ba 743. The RV for Se and Li were used as a preliminary approach to assess soil contamination in Spanish soils. The results confirm human impact on Sr, As, Cd, Cr, Cu, Ni, Pb and Zn soil concentrations, but evidence no deviation from natural Se, Li, Co, V, Fe, Mn and Ba concentrations. The results obtained from the statistical analysis reveal significant correlations between some elements and clay and soil organic matter (SOM) contents, indicating that metal concentrations are controlled by soil composition. One particularly interesting finding is the high correlation coefficients obtained between SOM and Se, Cd, Cr, V, Fe, and Mn, and between clay and Cd, Zn, V, Fe and Mn. Once again, these facts confirm the role of SOM and clay minerals in soil functions and that soil is an ecosystem element responsible for maintaining environmental quality. [ABSTRACT FROM AUTHOR]

Abstract

Abstract: The objective of this study was to determine the selenium content in soils from the Region of Murcia (SE, Spain) and to study the possible relationship between mineralogical composition, soil properties and selenium content. In addition, generic reference level (GRL) for selenium was determined according to Spanish legislation. For this study, 490 samples were selected in areas subjected to agricultural activity or abandoned agricultural soils with natural vegetation. Five different zones were established in order to study selenium variability. Four different mineralogical groups were established, based on significant relationship with the mineralogical composition, and each sample was included in one mineralogical group. The results showed that the concentration of selenium is correlated with the electrical conductivity, sulphate content and with the mineralogical composition, particularly positively with quartz and in a negative way with calcite percentage. In addition, selenium level was positively correlated with the phyllosilicate content. Established GRL for selenium varies with the mineralogical group, having a great transcendence from the legal and economic points of view. [ABSTRACT FROM AUTHOR]

Abstract

The present study examined the cardiac effects of football training and running for inactive pre-menopausal women by standard echocardiography and tissue Doppler imaging. Thirty-seven subjects were randomized to two training groups (football: FG; n=19; running; RG; n=18) training 1 h with equal average heart rates twice a week for 16 weeks and compared with a matched inactive control group (CG; n=10). During the training period, left ventricular end-diastolic volume increased by 13% in FG and 11% in RG ( P<0.05). Left ventricular posterior wall thickness increased in FG from 8.5±1.4 to 9.0±1.3 mm ( P<0.05). Right ventricle diameter increased by 12% in FG and 10% in RG ( P<0.05). Tissue Doppler imaging demonstrated increased left ventricular systolic and diastolic performances in both training groups. Peak systolic velocity increased by 26% in FG and 17% in RG ( P<0.05) and left ventricular longitudinal displacement increased in both groups by 13% ( P<0.05). Isovolumetric relaxation time decreased significantly more in FG than in RG (26% vs 14%, respectively P<0.05). In conclusion, 16 weeks of football and running exercise training induced significant changes of cardiac dimensions and had favorable effects on both left ventricular systolic and diastolic function. These training-induced cardiac adaptations appeared to be more consistent after football training compared with running. [ABSTRACT FROM AUTHOR]

Abstract

Background: The main reason for hospital stay after laparoscopic ventral hernia repair (LVHR) is probably pain, which also causes a lengthening of the patient's time to assume normal daily activities and work. It is likely that titanium tacks may be the main contributing factor to early (and maybe chronic) pain after LVHR. Therefore, non-invasive and patient-friendly mesh fixation methods must be considered. The present study was designed to investigate the technical applicability, safety and effect of Tisseel for intraperitoneal mesh fixation.Methods: Nine 40-kg Danish Landrace female pigs had two pieces of MotifMESH and two pieces of Proceed mesh fixed in the intraperitoneal position by a laparoscopic technique. The two pieces of the same mesh were fixed with fibrin glue (Tisseel) and titanium tacks, respectively. All pigs were euthanised on the 30th postoperative day and the mesh-tissue samples were tested for strength of ingrowth (peel test), adhesion formation, mesh shrinkage and examined for histological alterations.Results: No meshes were displaced from their initial position at autopsy, but we observed two cases of mesh folding that could have resulted in hernia recurrence in real patients. There were no significant differences in the strength of ingrowth between different mesh types or fixation methods, measured as peel work per area of mesh (J/m2) and peak force per width of mesh (Nmax/cm). The Proceed mesh shrank by 11% compared to 4% for the MotifMESH mesh (p = 0.002). There was no difference in the grade of adhesions (%) between fixation methods (p = 0.794) or different mesh types (p = 0.296). In the same fashion, there was no difference in the strength of adhesions (grades 0-4) between the two fixation methods or different mesh types (p > 0.5, chi2 test). There was no significant difference in the formation of fibrosis or inflammation between the different meshes or fixation methods. All samples showed significant foreign-body reaction with giant cells.Conclusion: Our results suggest that the laparoscopic fixation of an intraperitoneal mesh with Tisseel is safe and technically feasible in a pig model. There is still no evidence that fibrin-sealing alone is appropriate for intraperitoneal mesh fixation in hernia repair, but the technique might become an alternative or supplement to mechanical mesh fixation. Until then, further experimental research in animal hernia models with larger meshes is needed, especially with a focus on mesh folding and displacement. [ABSTRACT FROM AUTHOR]

Abstract

Abstract: Mining and milling operations, including grinding, concentrating ores and disposal of tailings, along with mine and mill waste water, provide obvious sources of contamination in the surface environment. Climatic effects such as heavy rainfall events, have a great impact in the dispersion of metals in semi-arid areas, since soils are typically scarcely vegetated. The dispersion and influence of soluble and particulate metals present in the materials from an abandoned mine, Cabezo Rajao, in SE Spain, was evaluated. Tailings and soils were sampled and analysed for pH, EC, CaCO3, grainsize, mineralogical composition and heavy metal content, while water samples were collected and analysed for pH, EC, soluble metals and salts. The mean concentrations of Pb, Zn, Cd, Cu and As in solid samples were 8.3 g kg−1, 12.5 g kg−1, 40.9 mg kg−1, 332.1 mg kg−1, 314.7 mg kg−1 respectively, and 1.5 mg l−1, 50.3 mg l−1, 13.6 g l−1, 17.2 mg l−1, 1.7 mg l−1 in water samples respectively. These metals can be dispersed downstream and downslope from the tailings by water after rainfall. Soil samples collected in the surroundings of Mar Menor Lagoon were analysed, reflecting the influence of the transport of soluble and particulate materials from Cabezo Rajao, especially of Pb and Zn. However, the presence of high amounts of carbonate in the soils around the mine area revealed the stabilization of all the metals studied. [Copyright &y& Elsevier]

Abstract

Abstract: A study on metal mobilisation (Zn, Pb and As) from contaminated sediments in Portman Bay (SE Spain) was carried out. This area has suffered a major impact from mining activity, as millions of tons of mine tailings have been dumped into the bay over a long period, gradually filling the bay. A three-step sequential extraction procedure, modified from the BCR (Community Bureau of Reference) method, as well as selective extractions (H2O, 0.1 N HNO3, citrate–dithionite and 1 M NH4OAc after H2O2 attack) were applied to selected samples in order to evaluate the potential mobility of fixed metals. Acid volatile sulfides (AVS) and simultaneously extracted metals (SEM) were also determined. X-ray diffraction (XRD) and scanning electron microscopy coupled to with an energy-dispersion spectrometry (SEM-EDS) were applied to the characterization of both raw samples and the residues remaining after each extraction, providing additional information about the sediment phases carrying the metals studied. Metals associated with sediments showed different behaviour depending on the mineralogical phase they were bound to. Zn was the most labile metal, while Pb and As showed a lower mobility. The fraction of metals associated with jarosites presented a high stability under different physicochemical conditions, while metals associated with mineralogical phases that are undergoing supergenic alteration processes presented a high mobility. The results obtained may be useful to assess both the short and the long-term environmental impact of such disposal activities as well as supporting decisions for a future remediation of the zone.
