Abstract
The optic discs of dogs exhibit considerable size, shape, and colour variations, depending on the degree of myelination. This variability makes the interpretation of lesions difficult, owing to the lack of reference patterns. This study aimed to compare optic nerve head (ONH) parameters determined by digital planimetry (DP) in two pure-bred dogs, Spanish Greyhound (SG) and Spanish Water Dog (SWD). The vertical and horizontal diameters, area, circularity, and the proportion of the ONH at the tapetal or non-tapetal zone (top height and bottom height) were calculated using image treatment software and compared between breeds. Significant between-breed differences were detected for all parameters, with SWD exhibiting greater height, width, area, top height, and lower circularity of the ONH than SG. Linear regression revealed that age significantly influenced mean disc height (R2 = 0.310; p = 0.0001), mean disc width (R2 = 0.280; p = 0.0001), mean disc area (R2 = 0.281; p = 0.0001), and circularity (R2 = 0.243; p = 0.0001). The multiple regression model significantly predicted mean disc height, width, and area [(S) (R2 = 0.715; p = 0.001), (R2 = 0.742; p = 0.001), and (S) (R2 = 0.736; p = 0.001), respectively], based on age and breed. Excellent concordance was observed between the measurements of experienced and novice researchers, and there were no differences between the parameters measured by the researcher and those obtained by the software. Planimetric ONH measurements can be easily performed by novice operators using a portable fundus camera and digital computer software. These results may be of considerable clinical value, but further studies are required because of the great variability of the ONH in dogs.

Abstract
OBJECTIVE The IDEAL Schedule was developed for staging "care needs" in patients with dementia. We here aim to validate the Spanish version, further test its psychometric properties and explore a latent construct for "care needs". METHODS A multicenter study was done in 8 dementia care facilities across Spain. Patients referred with a reliable ICD-10 diagnosis of dementia (n = 151) were assessed with the IDEAL Schedule by pairs of raters. Inter-rater reliability (intra-class correlation [ICC] coefficients), internal consistency (Cronbach's alpha), and factor analysis were calculated. Convergent validity for individual items was tested against validated Spanish versions of international instruments. RESULTS Pilot testing with numerical scales supported the feasibility, face, and content validity of the schedule. The psychometric coefficients were good/clinically acceptable: inter-rater reliability (mean ICC = 0.861; 85% of the ICCs > 0.8), internal consistency (global alpha coefficient = 0.74 in 5 nuclear items), and concurrent validity (global score against the Clinical Dementia Rating schedule, r = 0.63; coefficients for individual items ranging from 0.40 to 0.84, all statistically significant, p < 0.05). Internal consistency was low for the "nonprofessional care" and "social support" dimensions. Factor analysis supported a unidimensional solution, suggesting a latent "care needs" construct. CONCLUSION The Spanish version of the IDEAL Schedule confirms the main psychometric properties of the original version and documents for the first time the convergent validity of individual items. Factor analysis identified a latent construct consistent with the concept "care needs" although 2 dimensions need further psychometric research.

Abstract
OBJECTIVE To evaluate the effect of low-density lipoprotein receptor (LDLr) and IL28B genotypes on hepatitis C virus (HCV) viral kinetics in the first 4 weeks of treatment with pegylated-interferon (PEG-IFN)/ribavirin (RBV) in HIV patients co-infected with HCV genotype 1. METHODS HIV patients co-infected with HCV genotype 1 and naïve to PEG-IFN/RBV treatment were enrolled in a prospective study. HCV RNA viral loads were measured at baseline and at weeks 1, 2 and 4 after start of therapy. Differences in viral load decline were evaluated for IL28B (CC versus non-CC) and LDLr (CC versus non-CC) genotypes between baseline and weeks 1, 2 and 4. Additionally, the effect of LDLr genotype on HCV viral decline in IL28B CC genotype patients (CC/CC versus CC/non-CC) was analyzed. RESULTS Eighty-seven HIV/HCV genotype 1 co-infected patients were included in the study. Patients carrying the LDLr-CC or IL28B-CC genotypes showed greater HCV viral decline than those with IL28B non-CC or LDLr non-CC genotypes at every time-point analyzed. CC/CC patients had higher rapid virological response (RVR) rates than CC/non-CC patients (41.2 versus 13.3%; P < 0.001). Moreover, at all time points, the CC/CC pattern was associated with greater HCV viral decline than the CC/non-CC genotype (week 1: 1.18 ± 0.51 versus 0.31 ± 0.29, P = 0.041; week 2: 1.55 ± 0.81 versus 0.93 ± 0.73, P = 0.032; week 4: 2.23 ± 1.1 versus 1.5 ± 0.94, P = 0.039). CONCLUSION The LDLr genotype impacts on viral kinetics during the first days of starting treatment with PEG-IFN/RBV in HIV/HCV genotype 1 co-infected patients, and modifies the impact of IL28B on HCV viral decay.

Abstract
OBJECTIVES To evaluate the effect of the interleukin 28B (IL-28B) genotype on hepatitis C virus (HCV) viral kinetics in the first 4 weeks from start of treatment with pegylated interferon plus ribavirin (PEG-IFN/RBV) in HIV/HCV co-infected patients. METHODS HIV/HCV co-infected patients naive to PEG-IFN/RBV treatment were enrolled in a prospective study. HCV RNA plasma viral loads were measured at baseline and at weeks 1, 2 and 4 after commencement of treatment. Patients were grouped by HCV genotype (genotype 1/4 versus 3) and by IL-28B genotype (CC versus non-CC). Differences in viral load reduction were evaluated by IL-28B genotype between baseline, week 1, week 2 and week 4. RESULTS One hundred and nineteen HIV/HCV patients were included in the study. HCV patients with genotype 1/4 and bearing the IL-28 CC genotype showed the greatest reductions in HCV RNA plasma levels between baseline and weeks 1 (B-1), 2 (B-2) and 4 (B-4) than did those with non-CC genotypes (B-1: 1.06 ± 0.89 versus 0.48 ± 0.48 log IU/mL, P = 0.009; B-2: 1.36 ± 0.72 versus 0.77 ± 0.66 log IU/mL, P = 0.01; and B-4: 1.91 ± 0.64 versus 1.38 ± 0.96 log IU/mL, P = 0.03). However, differences between weeks 1 and 2 (W1-2) and between weeks 2 and 4 (W2-4) were not associated with the IL-28B genotype (W1-2: CC 0.48 ± 0.42 versus non-CC 0.38 ± 0.38 log IU/mL, P = 0.62; W2-4: CC 0.32 ± 0.23 versus non-CC 0.39 ± 0.31 log IU/mL, P = 0.67). No differences in decline of HCV RNA viral load were found in HCV genotype 3 patients. CONCLUSIONS The IL-28B genotype impacts on viral kinetics during the first week of treatment with PEG-IFN/RBV in patients with HCV genotype 1/4.

Abstract
This work aims to contribute to the implementation of the WFD with regard to the selection of the measures for a sustainable and socially accepted water management. A multicriteria decision support exercise is applied to the Guadalquivir River Basin in order to test the applicability of the Analytic Hierarchy Process in the new WFD context. A survey was carried out in the context of a future enlargement of La Breña reservoir (Córdoba). This analysis aims to obtain the public’s weight of the criteria in water management, in order to assess the legitimacy of the reservoir enlargement, as well as other management measures. Results suggest that the AHP is an adequate tool for the WFD purposes and a useful complement for the cost-effectiveness analysis.

Abstract
OBJECTIVE The aims of this study were to appraise the predictive value of variations in a single-nucleotide polymorphism (SNP) in the low-density lipoprotein receptor (LDLR) gene for sustained virological response (SVR) to pegylated interferon (Peg-IFN) and ribavirin (RBV), as well as to analyze the relationship between LDLR genotype and other predictors of SVR, particularly IL28B genotype, in patients coinfected with HIV and hepatitis C virus (HCV). METHODS One hundred and eighty-four HIV/HCV-coinfected, treatment-naive patients with chronic HCV infection, who received Peg-IFN and RBV, were included. Variations in the SNP rs14158 and rs12979860 were tested by Taqman PCR assay. RESULTS Twenty-eight (38%) patients with rs14158 TT/TC and 61 (55%) with CC (P = 0.028) achieved SVR. The rates of SVR in patients with rs14158 TT/TC and with CC harboring HCV 1-4 were 20 and 41% (P = 0.020), respectively, and, in those with HCV genotype 2-3, 75 and 84% (P = 0.513), respectively. Patients with rs14158 CC showed less commonly plasma HCV-RNA load at least 600000 IU/ml (57 vs. 71%, P = 0.047) and lower likelihood of relapse (13 vs. 30%, P = 0.023). In patients with HCV genotype 1-4, the rates of SVR according to the combination of IL28B/LDLR genotypes were: CC/CC = 69%; CC/non-CC: 30%; non-CC/CC: 25%; non-CC/non-CC: 14% (P < 0.001). CONCLUSION Variations in rs14158 are associated with SVR to Peg-IFN and RBV in HIV/HCV-coinfected patients harboring HCV genotype 1-4. LDLR and IL28B genotypes seem to have a synergistic effect on SVR. The combined use of LDLR and IL28B genotypes in routine clinical practice could enhance the predictive value of IL28B genotype alone.

Abstract
The essential helicase loader protein G39P encoded by Bacillus subtilis SPP1 phage has been overproduced in Escherichia coli and purified. The wild-type protein has been crystallized by the hanging-drop vapour-diffusion method in a primitive hexagonal space group, probably P6(1)22/P6(5)22, but the crystals diffract to only 3.4 A and are poorly reproducible. Mass-spectrometric analysis has revealed marked proteolytic cleavage from the C-terminus and the presence of a major species corresponding to deletion of the 14 C-terminal residues. Thus, a new variant of the protein (G39P112) has been engineered that corresponds to a 14-residue C-terminal truncation. The G39P112 variant has also been crystallized but now in a primitive orthorhombic form, probably P2(1)2(1)2 or P2(1)2(1)2(1), with unit-cell parameters a = 85.6, b = 89.7, c = 47.6 A, with diffraction to 2.4 A on a synchrotron source and with greatly improved reproducibility. Calculation of V(M) values for this G39P112 variant suggests the presence of three monomers in the asymmetric unit, corresponding to a solvent content of about 47%. A selenomethionine-incorporated form of the protein has been produced and a full three-wavelength MAD data collection undertaken.

Abstract
Cerebral static autoregulation (AR) was evaluated at bedside in 14 severely head injured patients. 16 investigations were performed. Cerebral perfusion pressure (CPP) was increased by infusing vasopressors during one hour, and registered every 2-5 minutes. CBF was simultaneously estimated by: 1) middle cerebral artery mean flow velocity (FV) monitoring with Transcranial Doppler (TDC), and 2) the reciprocal of arteriovenous oxygen content difference, calculated from basal and hypertensive arterial and jugular bulb blood samples. AR assessment: For TCD results, linear regression method was used, studying two pairs of variables: a) %FV-CPP (the regression slope was the main AR value adopted) and b) % cerebrovascular resistance (CVR)-%CPP. For the AVDO2 method, autoregulation was considered preserved if estimated % delta CBF/delta PPE < 1%/mm Hg. TCD method clearly defined three groups. Group 1 and 2 (8 and 5 investigations) were considered as two grades of preserved AR, and the third one (3 cases) as impaired AR. AVDO2 method: 12 studies were evaluated. 10 showed preserved AR, and 2 impaired AR. There was coincidence of results from both methods in 10 out of 12 studies. (0.83).

Abstract
Cytomegalovirus encephalitis is rarely diagnosed in immunocompetent patients. It is more frequent among immunocompromised hosts. We present a case of a young male patient without evidence of immunosupression who had a cytomegalovirus encephalitis. The diagnosis was made by detection of viral DNA in cerebral tissue obtained by biopsy. Neuropathologic and ultrastructural changes are described and compared with the descriptions in immunocompromised patients.

Abstract
We studied the sensitivity of 160 strains of Bacteroides fragilis (74 beta-lactamase-positive and 86 beta-lactamase-negative) to four third-generation cephalosporins, alone as well as in combination with clavulanic acid and Sulbactam. For susceptibility testing we used a dilution method in agar. Detection of beta-lactamase production by this micro-organism was performed using chromogenic cephalosporin (Nitrocefin). There was a substantial improvement in cephalosporin activity with both positive and negative strains when they were combined with the inhibitors, although this was more significant in beta-lactamase-producing organisms. Generally, the results achieved in combination with clavulanic acid were better than those with Sulbactam, the highest increase in activity being obtained with Ceftizoxime in combination with any one of the inhibitors.
