Abstract
Started with tuberculosis and developed in parallel with smoking and cancer and under the protection of anaesthesia, thoracic surgery appeared in the 1980's as a specialty with a difficult long-term survival. However, with the development of lung transplant, tracheal surgery, the appearance of video-assisted thoracic surgery, along with the confirmation that despite the excellent progress of chemoradiotherapy, surgery continues to be the best option for curing lung cancer, means that it is currently a specialty of great growth and a wider scope in the future.

Abstract
There is little information about patients with severe aortic stenosis (SAS) who require admission to acute care units. We studied 27 patients with SAS admitted in a tertiary hospital coronary care unit. The most frequent reasons for admission were severe heart failure (42%), acute coronary syndrome (39%) and cardiac arrest (8%). At a mean follow-up of 6.5 months, 11 patients died. Cumulative survival was 74±8%, 70±9%, and 62±10% at 7, 30 and 60 days, respectively. Out of the 27 patients, 13 (48%) underwent surgical intervention, these patients having lower Euroscore (13±11 vs. 34±18%, p=0.002) and higher survival (92±7% at 7, 30 and 60 days vs. 50±13%, 40±14% and 30±14%; p=0.002). Thus, patients with SAS who require hospitalization in the intensive care units constitute a very high risk population, with very high mortality, especially during the first week after admission and in patients who have not undergone surgery.

Abstract
The magnetic structures of the title compounds have been studied by neutron diffraction. In contrast to the isomorphous RNi(2)B(2)C compounds, wherein a variety of exotic incommensurate modulated structures has been observed, the magnetic structure of ErCo(2)B(2)C is found to be a collinear antiferromagnet with [Formula: see text] while those of HoCo(2)B(2)C and DyCo(2)B(2)C are observed to be simple ferromagnets. For all studied compounds, the moments are found to be confined within the basal plane and their magnitudes are comparable to the values obtained from the low-temperature isothermal magnetization measurements. The absence of modulated magnetic structures in the RCo(2)B(2)C series (for ErCo(2)B(2)C, verified down to 50 mK) is attributed to the quenching of the Fermi surface nesting features.

Abstract
Among the factors that affect the efficiency of somatic cell nuclear transfer (SCNT) in pigs, the activation protocol is the most variable among the current SCNT procedures. The aim of this study is focused on defining an efficient activation treatment of porcine oocytes. In Experiment 1, we studied the effects of nine different oocyte activation procedures (including chemical- and electrical-based treatments) on parthenogenetic embryo development. In Experiment 2, we studied the effect of the more efficient activation procedures on the gene expression profile of Oct4 and Igf2r in parthenogenetic blastocysts. In conclusion, ionomycin as a first calcium stimulus is not able to activate porcine oocytes efficiently in comparison with electric procedures. Electrical treatments with 6-DMAP significantly increased the level of Oct4 expression, whereas the single and double pulse treatments alone maintained the same profile as the IVF group.

Abstract
Endothelial dysfunction is characterized by an impairment of endothelium-dependent vasodilatation. It has been linked to each of the known atherogenic risk factors, including diabetes mellitus, hypertension, dyslipidaemia, cigarette smoking, menopause, etc. A number of recent studies have shown that the severity of endothelial dysfunction correlates with the development of coronary artery disease and predicts future cardiovascular events. Therefore, these findings strengthen the hypothesis that endothelial dysfunction may be an early stage of coronary atherosclerosis. This phenomenon primarily reflects an imbalance between the vasodilating (nitric oxide) and vasoconstrictor agents (endothelin-1). Several invasive (intracoronary or intrabrachial infusions of vasoacting agents) and non-invasive techniques (assessment of flow mediated vasodilatation in the brachial artery by ultrasound) have been developed during the last few years to evaluate endothelial function in the coronary and peripheral circulation. This new methodology has allowed assessing the severity of the abnormalities in vascular function and their regression by several pharmacological and non-pharmacological interventions. It is likely that restoration of endothelial function can regress the atherosclerotic disease process and prevent future cardiovascular events. Most pharmacological interventions attempting to improve endothelial dysfunction targeted the risk factors linked to endothelial dysfunction: hypertension (ACE-inhibitors, calcium antagonists), dyslipidaemia (lipid-lowering agents) and menopause (estrogens). Nevertheless, several pharmacological agents have been suggested to achieve vascular protection through different mechanisms beyond their primary therapeutic actions: ACE-inhibitors, statins, third generation of beta-blockers (nebivolol), endothelium-derived nitric oxide synthesis (tetrahydrobiopterin, BH4) and antioxidants agents. In this review we will focus on the current pharmacological management of the endothelial dysfunction.

Abstract
AIM To evaluate the efficacy of intensive lipid lowering treatment with atorvastatin versus standard doses of statins (simvastatin, atorvastatin, lovastatin or pravastatin) on the risk of stroke, using meta-analytic techniques. PATIENTS AND METHODS The meta-analysis included 5 randomized trials that met the inclusion criteria: comparison between intensive atorvastatin treatment (atorvastatin 80 mg or target LDL < 70 mg/dL) and standard doses of statins, with a clinical follow-up of more than 12 months and stroke as clinical endpoint. TNT (n = 9,917) atorvastatin 80 mg vs. 10 mg; IDEAL (n = 8,888) atorvastatin 80 mg vs. simvastatin 20-40 mg; PROVE-IT (n = 4,162) atorvastatin 80 mg vs. pravastatin 40 mg; ALLIANCE (n = 2,442) atorvastatin 80 mg or target LDL < 70 mg/dL vs. standard treatment; and VBBS (n = 300) atorvastatin 80 mg vs. low dose lavastatin. The selected studies included secondary prevention patients (acute coronary syndrome, stable coronary disease and patients eligible for angioplasty). 25,709 patients were included (12,910 allocated to intensive atorvastatin treatment, and 12,799 to standard doses of statins). Stroke incidence, as reported from each trial, was compared between both treatments. RESULTS Out of the 25,709 patients, 713 (2.77%) suffered a stroke during follow-up. The incidence of stroke was significantly reduced with intensive atorvastatin treatment in comparison with conventional doses of statins: 2.52% (n = 325) vs. 3.03% (n = 388); relative risk = 0.83; 95% confidence interval = 0.72-0.96; p = 0.0121. CONCLUSIONS Intensive lipid lowering treatment with atorvastatin is associated with a 17% relative risk reduction of stroke in comparison with conventional doses of statins in secondary prevention population.

Abstract
Based on magnetization, specific heat, magnetostriction and neutron-diffraction studies on single-crystal TbCo(2)B(2)C, it is found out that the paramagnetic properties, down to liquid nitrogen temperatures, are well described by a Curie-Weiss behavior of the Tb(3+) moments. Furthermore, below T(c) = 6.3 K, the Tb sublattice undergoes a ferromagnetic (FM) phase transition with the easy axis being along the (100) direction and, concomitantly, the unit cell undergoes a tetragonal-to-orthorhombic distortion. The manifestation of an FM state in TbCo(2)B(2)C is unique among all other isomorphous borocarbides, in particular TbNi(2)B(2)C (T(N) = 15 K, incommensurate modulated magnetic state) even though the Tb ions in both isomorphs have almost the same crystalline electric field properties. The difference among the magnetic modes of these Tb-based isomorphs is attributed to a difference in their exchange couplings which are in turn caused by a variation in their lattice parameters and in the position of their Fermi levels.

Abstract
Antidepressants increase melatonin levels, but it is still unclear whether this effect is related to the improvement of depressive symptoms or to unrelated pharmacological action of antidepressants. To answer this question, the effect of antidepressants on 6-sulphatoxymelatonin (aMT6s), the main melatonin urinary metabolite, was examined in drug-free depressed patients - most of them antidepressant-naive. aMT6s was evaluated in 34 depressed patients, before and after 8 weeks of placebo (n = 12) or antidepressant (n = 22; fluoxetine, duloxetine or Hypericum perforatum). Both groups showed an improvement of depressive symptoms after treatment compared to baseline (Hamilton Depression scores): 17.0 +/- 1.4 vs. 9.0 +/- 2.8, P = 0.007 for placebo, and 18.6 +/- 1.1 vs. 11.8 +/- 1.6, P < 0.001 for antidepressants). After treatment, aMT6s levels increased after antidepressants (P < 0.01), but not after placebo (P > 0.05). As depressive symptoms improved both in patients taking antidepressant and in those taking placebo, but an effect of antidepressants could only be seen in those taking antidepressants, we suggest that melatonin changes after antidepressants are more likely due to a pharmacological action of these drugs on melatonin secretion.

Abstract
AIM Factors affecting faecal indicator bacteria (FIB) and pathogen survival/persistence in sand remain largely unstudied. This work elucidates how biological and physical factors affect die-off in beach sand following sewage spills. METHODS AND RESULTS Solar disinfection with mechanical mixing was pilot-tested as a disinfection procedure after a large sewage spill in Los Angeles. Effects of solar exposure, mechanical mixing, predation and/or competition, season, and moisture were tested at bench scale. First-order decay constants for Escherichia coli ranged between -0.23 and -1.02 per day, and for enterococci between -0.5 and -1.0 per day. Desiccation was a dominant factor for E. coli but not enterococci inactivation. Effects of season were investigated through a comparison of experimental results from winter, spring, and fall. CONCLUSIONS Moisture was the dominant factor controlling E. coli inactivation kinetics. Initial microbial community and sand temperature were also important factors. Mechanical mixing, common in beach grooming, did not consistently reduce bacterial levels. SIGNIFICANCE AND IMPACT OF THE STUDY Inactivation rates are mainly dependent on moisture and high sand temperature. Chlorination was an effective disinfection treatment in sand microcosms inoculated with raw influent.

Abstract
OBJECTIVE The aim of this study was to know the frequency of bacteremias produced by Staphylococcus aureus and the sensibility that strains showed, as well as the clinical characteristics of the patients. METHOD We retrospectively studied cases of S. aureus bacteremia detected in our hospital from 2001 to 2005 and also reviewed medical histories from patients during 2005. RESULTS A total of 295 cases of S. aureus bacteremia were detected in this study. Annual distributions of the cases were as follows: 35, 54, 62, 64 and 80. By gender, 62.7 % related to males and 37.3 % to females. A total of 58.6 % of the patients were admitted to medical services and 49 % were older than 65 years. Regarding resistance, 34 % of the strains showed resistance to oxacillin, 33 % to ciprofloxacin, 41 % to erythromycin and 4.4 % to gentamicin. In one-third of the patients, S. aureus was isolated in other samples, the catheter being the most common. A total of the 73.5 % of the patients had some baseline disease and the most frequent predisposing factor was the intravascular catheter. The bacteremias were nosocomial-acquired in 73.5 % of the cases. CONCLUSIONS In our hospital, S. aureus bacteremia and oxacillin resistance has been increasing over the years of this study.

Abstract
The purpose of this study was to determine whether genetically similar or diverse strains of Listeria monocytogenes colonize the environment and carcasses in a single Spanish broiler abattoir over time. The study was composed of 5 surveys over a 1.5-yr period and included the monitoring of cleaning and disinfection procedures. Overall, a total of 212 samples were tested for the presence of L. monocytogenes, and 31% of the samples were found to be positive. Listeria monocytogenes was isolated from carcasses and product contact and noncontact sites in the evisceration and carcass classification areas of the abattoir. A total of 132 L. monocytogenes isolates were characterized by PCR-based serotyping and pulsed-field gel electrophoresis (PFGE) restriction analysis with the endonucleases ApaI and AscI. Molecular serotyping showed that L. monocytogenes isolates were of serotypes 1/2a and 1/2b. Isolates of serotype 1/2b (89.4%) were contaminating carcasses as well as environmental product contact and noncontact sites, whereas isolates of serotype 1/2a (10.6%) were recovered only from environmental product noncontact sites. A relatively low genetic diversity was found in this group of L. monocytogenes isolates from the abbatoir; only 14 different PFGE types (A1 to A14) were obtained. Nine pulsotypes belonging to serotype 1/2b (lineage I) were grouped in only one PFGE genetic cluster, whereas 5 pulsotypes belonging to serotype 1/2a (lineage II) were grouped into 4 PFGE genetic clusters. Two genetically related pulsotypes of serotype 1/2b (A1 and A2, 64.4% of the isolates) predominated and persisted in the abattoir. Our study indicated that a few strains of L. monocytogenes lineage I that were genetically very closely related might be specifically adapted to colonizing the evisceration zone of the abattoir and were predominant on carcasses over 1 yr. On the other hand, a genetically diverse group of lineage II strains were present in the abattoir environment, but never contaminated carcasses.

Abstract
BACKGROUND the natural history of recurrent hepatitis C after liver transplantation (LT) is extremely variable, with progression to allograft failure in a substantial proportion of patients. The identification of factors associated with this poorer outcome may improve results. While donor age has been identified as one of the most important factors, the actual options to modify this variable are limited. OBJECTIVES a) to describe the natural history of HCV(+) liver transplant recipients depending on donor age ( < or = 50 years), including clinical, biochemical, and histological outcomes; and b) to identify in the subgroup of organ recipients from aged donors (= 50 years) factors associated with an aggressive course. METHODS a retrospective study of clinical and histological data including protocol liver biopsies for 162 HCV (+) liver transplant patients between 1997 and 2001 with at least one year of follow-up. Aggressive recurrent hepatitis C was defined as a progression to fibrosis > 1 during the first year post-LT, development of a cholestatic form of recurrent hepatitis C, and /or graft failure due to HCV during the first five years post-LT. Factors analyzed as potentially associated with recurrent hepatitis C included: a) recipient-related: demographics (age, sex), pre-transplantation (hepatocellular carcinoma, Child-Pugh classification, history of alcohol, HBV serological markers, antiviral treatment, nutritional status, biochemical variables); b) donor-related: demographics (age, sex), cause of death, grade of steatosis defined as minimal vs. moderate-severe > 10%); c) surgery-related: cold preservation and rewarming time, duration of procedure, blood transfusion; and d) post-LT management-related: immunosuppression, liver enzymes in the first 14 days post-LT, acute hepatitis post-LT, surgical complications (vascular and/or biliary). RESULTS patients were divided into two groups according to donor age group 1 ( < 50 years), n = 83, 51%, and group 2 (= 50 years), n = 79, 49%). Median follow-up was 5 years (range: 3 months-8.5 years). Aggressive recurrent hepatitis C occurred significantly more frequently in the older donor group (64 vs. 20.5%, p < 0.0001). In this group, potent immunosuppression -triple and quadruple regimens- (p = 0.04) and acute hepatitis post-LT (p = 0.03) were the only variables associated with aggressive recurrence. Degree of donor steatosis was not associated with the prognosis of recurrent hepatitis C. CONCLUSION the use of aged donors is partly responsible for the accelerated progression of hepatitis C after LT. When old donors are used we should avoid over-immunosuppression, and probably evaluate antiviral therapy in those with acute recurrent hepatitis C.

Abstract
The no-reflow phenomenon (NRP) is characterized by an inadequate myocardial tissue perfusion in the presence of a patent epicardial coronary artery. It generally occurs after temporary occlusion of the artery causing myocardial ischemia and necrosis that persist after relief of the vessel occlusion, without evidence of epicardial mechanical obstruction. Currently, the main scenario of NRP is the setting of percutaneous coronary interventions (PCI), especially in patients with acute myocardial infarction or saphenous vein graft disease, and its occurrence is associated with adverse clinical outcomes. Pathophysiology of NRP is not fully understood but it seems to be related with microvascular damage. Several mechanisms have been involved, such as distal microembolization, interstitial and intracellular edema, coronary spasm and capillary plugging. Diagnosis of NRP is generally based on clinical and angiographic data. Several methods have been proposed for the assessment of NRP, such as electrocardiography, myocardial contrast echocardiography, contrast-enhanced magnetic resonance imaging, nuclear imaging or positron emission tomography, that have demonstrated additional prognostic value over angiography. There are different pharmacological and mechanical approaches for the prevention of NRP but none of them have demonstrated a clear efficacy. The treatment of established NRP is mainly based on the administration of coronary vasodilators, like adenosine, verapamil or nitroprusside, but clinical results are frequently disappointing. The objective of this review is to describe the state of the art of the pathophysiology, diagnosis and pharmacological management of NRP.

Abstract
BACKGROUND AND AIM The -250G/A promoter polymorphism of the hepatic lipase gene has been associated with changes in the activity of the enzyme. We investigated whether this polymorphism modifies the postprandial response of triacylglycerol-rich lipoproteins (TRL) in young normolipemic males. METHODS AND RESULTS Fifty-one healthy apolipoprotein (apo) E3/E3 male volunteers (30 G/G and 21 carriers of the A allele) underwent a vitamin A fat-loading test and blood samples were drawn every hour until the 6th, and every 2h and 30 min until the 11th. Total plasma cholesterol and triacylglycerols (TG), as well as cholesterol, TG and retinyl palmitate (RP) in TRL, isolated by ultracentrifugation, were determined. Carriers of the A allele showed a higher response (P=0.008), a higher area under the curve (AUC; P=0.022) and a lower RP peak time (P=0.029) in small TRL during the postprandial response, as well as a lower peak time in total plasma TG levels (P=0.034) and large TRL-TG (P=0.033) than subjects who were homozygous for the G allele. CONCLUSION Our data indicate that the presence of the A allele in the -250G/A promoter polymorphism of the hepatic lipase gene is associated with a higher postprandial lipemic response.

Abstract
Microdissection electrodes (MEs) have previously been used to perform endoscopic cordectomies. We designed a prospective study in order to compare the ME with the CO2 laser technique. Over two years, 20 patients with T1 glottic carcinoma were operated on with CO2 laser and 20 with MEs. The device was chosen alternatively for each new patient. Two patients in both treatment groups had slight glottic incompetence. Three patients in each group showed web formation. The only granuloma was observed in a CO2 laser patient. Seven of the ME patients developed slight dysphonia, 10 developed medium grade dysphonia and three developed severe dysphonia. Seven of the CO2 laser patients developed slight dysphonia, seven developed medium grade dysphonia and six developed severe dysphonia. No statistically significant differences were observed on comparing the grade of dysphonia with patient age, T stage, type of cordectomy or surgical device. We consider the ME to be a useful and inexpensive alternative to CO2 laser.

Abstract
A simple solution to the problem of a broken depth gauge is suggested. A hypodermic needle is bent to simulate the shape of a depth gauge and used in a similar way. This allows measurement of the screw length against the scale on the set. We would advocate this method only when there is no suitable alternative depth gauge available.

Abstract
OBJECTIVE To evaluate the potential role of intravascular ultrasound (IVUS) in evaluating patients experiencing an episode of acute stent thrombosis. DESIGN AND SETTING Prospective observational study in a cardiac catheterisation laboratory in a university teaching hospital. PATIENTS AND INTERVENTIONS IVUS was used to examine 12 patients undergoing coronary interventions for stent thrombosis to gain further mechanistic insights and to guide treatment. IVUS studies were obtained before and after intervention with a motorised pullback device. MAIN OUTCOME MEASURES Qualitative and volumetric IVUS analyses. RESULTS Angiographically, 10 patients had occluded vessels and two patients had intraluminal filling defects within the stent. IVUS showed an occlusive thrombus in all patients. Thrombus volume was 90 (77) mm3, which was 51 (21)% of total stent volume. There was evidence of severe stent underexpansion in most patients and no patient fulfilled standard criteria for optimal stent implantation. Stent malapposition was detected in four patients, edge dissections were seen in two patients, and significant inflow-outflow disease was present in 11 patients. During interventions IVUS findings led to the use of higher pressures or larger balloons than those used during initial stenting in 10 patients. In addition, four patients required additional stenting, whereas a thrombectomy device alone was selected for one patient. After the procedure final minimum stent area (7.1 (2.1) v 5.3 (2) mm2, p < 0.005) and stent expansion (83.2 (17) v 62.1 (15)%, p < 0.005) improved compared with pre-interventional values. However, residual lining thrombus was still visualised in eight patients (25 (19) mm3, accounting for a 17% of final stent volume). CONCLUSIONS IVUS provides an attractive technique to characterise fully the pattern of stent thrombosis, to identify readily the underlying mechanical predisposing factors, and to guide repeated coronary interventions.

Abstract
Patients receiving recombinant human erythropoietin (rHuEPO) therapy show wide variability in their responsiveness to the drug. Variables that affect rHuEPO dose requirements can be broadly divided into modificable and immutable characteristics. Most of the scientific research on rHuEPO hyporesponsiveness has focused on modificable variables (iron status, dialysis adequacy), while immutable variables such as gender, etiology of chronic renal failure (CRF) and age have been insufficiently explored. A cross sectional study was performed in order to evaluate if immutable patient characteristics determine rHuEPO dose requirements among 215 patients (52% males; mean age 66 +/- 14 years) on hemodialysis (HD) for more than twelve months. Data were collected at 10 hemodialysis units in Aragon. Patients were divided into three groups according to their gender, their cause of CRF (diabetic nephropathy, vascular nephropathy, tubulointerstitial nephropathy and primary glomerulonephritis) and their age (younger than 60 years, from 60 to 75 years, older than 75 years). Despite a similar dose of rHuEPO, women had lower mean hemoglobin (11.1 +/- 1.5 versus 11.6 +/- 1.7 g/dl; p = 0.0258) than men. The greater hemoglobin in men than women may be attributed to greater serum albumin in men (3.5 +/- 0.3 versus 3.7 +/- 0.3 mg/dl; p = 0.0001). Requirements of rHuEPO were higher in the patients with etiology of primary glomerulonephritis compared with those with the other etiologies, even those with diabetic nephropathy (p = 0.0374). The rHuE-PO doses required to obtain similar hemoglobin levels were higher in patients younger than 60 years (p = 0.0249). We conclude that women, patients with primary glomerulonephritis as cause of CRF, and patients younger than 60 years showed the highest requirements of rHuEPO doses.

Abstract
INTRODUCTION Stent implantation without predilation simplifies a large proportion of coronary intervention procedures, with a significant reduction in costs and procedure time. OBJECTIVES To determine the variables associated with a higher probability of failure in direct stent implantation in daily practice in a wide range of clinical contexts and types of lesions. POPULATION AND METHODS Over a period of 28 months, direct implantation of 931 stents was attempted in our Center (811 patients, 83% male, mean age 62 +/- 12 years; 1.1 stent per patient). In 59 patients (7.3%), balloon predilation was necessary, and the factors associated with direct implant failure were determined. RESULTS The vessels treated were: anterior descending (373 lesions: 40.1%), right coronary artery (306 lesions: 32.9%, circumflex (210 lesions: 22.6%), saphenous vein (35 lesions: 3.8%), left main (5 lesions: 0.4%) and internal mammary artery (2 lesions: 0.2%). 54% of the lesions were of type B2/C (ACC/AHA classification). The characteristics significantly associated with, or with statistical tendency towards, a lower success rate in direct stent implantation were: Lesion in the circumflex (11% vs. 5.5%, p = 0.012); reference vessel diameter less than 3.0 mm (9.8% vs. 6.2%, p = 0.097); age over 65 years (8.5% vs. 4.5%, p = 0.017); left main disease, irrespective of the vessel treated (23.5%% vs. 6.5%, p = 0.023); B2/C lesion (7.8%, vs. 4.8%, p = 0.086); calcification (9.9% vs. 4.9%, p = 0.012); vessel angulation greater than 45 degrees (9.9% vs. 4.9%, p = 0.009); and Express stent implant (19.6% vs. 6.0%, p < 0.001). On multivariate analysis, independent predictors of failure in direct stent implantation were: left main lesion (RR 6.6; 95% CI 1.73-24.93; p = 0.013), presence of calcium (RR 1.9; 95% CI 1.02-3.37; p = 0.049), vessel curvature (RR 2.0; 95% CI 1.13-3.64; p = 0.018), reference vessel diameter less than 3 mm (RR 2.2; 95% CI 1.15-4.32; p = 0.023), lesion type B2/C (RR 1.9; 95% CI 1.0-3.52; p = 0.044) and Express stent (RR 2.7; 95% CI 1.07-6.79; p = 0.05). CONCLUSION In a large and heterogeneous series of patients, direct stenting was not possible in 7.3% of cases, which required balloon predilation. Certain clinical and angiographic features can predict when this is more like to occur.

Abstract
The different serotypes of Streptococcus pneumoniae isolated from adults aged over 64 years in the Valencia and Castellon health region of Spain from June 1999 to December 2003 were analyzed. A total of 163 strains were evaluated; 58.3% were invasive, 47.24% were from respiratory source, and 4.9% were from exudates. The greatest percentage of samples was obtained from the group of patients aged 65 to 75 years (60.7%), while the lowest percentage was obtained from the group of patients aged over 85 years (10.4%). In the latter group, 53% of the strains were invasive and 29.4% were isolated from sputum. A total of 21 serotypes were identified, with the most common (> 3%) being: serotype 3 (22.1%); serotype 19 (12.9%); serotype 6 (12.3%); serotype 9 (8.6%); serotype 14 (10.4%); serotype 23 (8%); serotype 29 (3.7%); and serotype 18 (3.1%). Serotype 3 was the most common serotype found in all samples, with the exception of exudate, while serotype 23 was not isolated in blood. In this population group, the coverage of the 23-valent vaccine was 88.4%. Serotypes not included in this vaccine but isolated from invasive samples were serotypes 16, 24, 29 and 35. No changes were observed in serotype distribution over the 4-year period of the study. However, it is necessary to continue epidemiological monitoring to determine whether serotype substitution occurs.

Abstract
Structural and microbial heterogeneity occurs in almost any type of biofilm system. General approaches for the design of biofilm systems consider biofilms as homogeneous and of constant thickness. In order to improve the design of biofilms systems, models need to incorporate structural heterogeneity and the effect of inert microbial mass. We have improved a 2D biofilm model based on cellular automata (CA) and used it to simulate multidimensional biofilms with active and inert biomass including a self-organizing development. Results indicate that the presence of inert biomass within biofilm structures does not change considerably the substrate flux into the biofilm because the active biomass is located at the surface of the biofilm. Long-term simulations revealed that although the biofilm system is highly heterogeneous and the microstructure is continuously changing, the biofilm reaches a dynamic steady-state with prediction of biofilm thickness and substrate flux stabilizing on a delimited range.

Abstract
INTRODUCTION The prevalence of C282Y homozygosity in patients with hereditary hemochromatosis (HH) has been reported to be markedly lower in the Mediterranean Basin than in northern Europe. In Spain, the available data are contradictory and limited to small series in specific regions. The objective of this study is to determine the prevalence of the 2 main HFE gene mutations in a large series of unrelated Spanish patients with HH from different geographical origins. PATIENTS AND METHOD The criteria for HH diagnosis were: repeat serum transferrin saturation index (> 45% plus C282Y homozygosity and/or hepatic iron index (> 1.9 of dry liver weight in non-cirrhotic patients or (> 4.1 in patients with liver cirrhosis. Cases in related individuals were excluded. Demographic data, clinical expression, iron parameters and HFE gene mutations (C282Y and H63D) were assessed in 222 patients. RESULTS A total of 83.3% of patients were C282Y homozygous and 5% were compound heterozygous (C282Y/H63D). No significant differences in phenotypic expression or in the frequency of C282Y homozygosity were observed between patients born in the North and South of Spain. CONCLUSION The genotypic and phenotypic expression of HH in Spain is very similar to that reported in Northern Europe. Thus, the genetic heterogeneity described in some Southern European regions cannot be considered a common feature to all countries of the Mediterranean Basin.

Abstract
BACKGROUND Doppler Tissue Imaging (DTI) has been evaluated in ischaemic heart disease and some cardiomyopathies. In patients with aortic stenosis (AS), left ventricular contraction is slowered. This study aimed to evaluate the possible role of the measurement of isovolumic contraction time (ICT) by DTI in the evaluation of AS severity. METHODS The study population constitutes 30 patients: 15 with AS (nine severe and six non-severe) and 15 control subjects. All of them had normal systolic function, sinus rhythm, and absence of ischaemic heart disease of conduction abnormalities. ICT was defined as the time from the onset of the QRS complex to the beginning of the DTI systolic wave. The correlation between ICT and aortic area obtained by continuity equation, as well as the diagnostic value of ICT in the identification of severe AS were studied. RESULTS ICT was significantly increased in patients with severe AS (98+/-27 versus 65+/-21 ms, p=0.024). There was a significant correlation between ICT and aortic area (r=-0.56; p=0.035). The receiver operator characteristic curve of ICT in the identification of severe AS yielded an area under the curve of 0.852 (95% confidence interval: 0.665-1.0). The two best cut-points were >73 ms (88% sensitivity, 77% specificity) and >85 ms (78% sensitivity, 83% specificity). A value of >41 ms had a 100% sensitivity, but only a 17% specificity, and >91 ms showed a 100% specificity, but only a 44% sensitivity. CONCLUSIONS ICT measured by pulsed-wave DTI is increased in patients with aortic stenosis.
