Background: Non-hereditary colorectal cancer (CRC) is a complex disorder resulting from the combination of genetic and non-genetic factors. Genome-wide association studies (GWAS) are useful for identifying such genetic susceptibility factors. However, the single loci so far associated with CRC only represent a fraction of the genetic risk for CRC development in the general population. Therefore, many other genetic risk variants alone and in combination must still remain to be discovered. The aim of this work was to search for genetic risk factors for CRC, by performing single-locus and two-locus GWAS in the Spanish population. Results: A total of 801 controls and 500 CRC cases were included in the discovery GWAS dataset. 77 single nucleotide polymorphisms (SNP)s from single-locus and 243 SNPs from two-locus association analyses were selected for replication in 423 additional CRC cases and 1382 controls. In the meta-analysis, one SNP, rs3987 at 4q26, reached GWAS significant p-value (p = 4.02x10-8), and one SNP pair, rs1100508 CG and rs8111948 AA, showed a trend for two-locus association (p = 4.35x10-11). Additionally, our GWAS confirmed the previously reported association with CRC of five SNPs located at 3q36.2 (rs10936599), 8q24 (rs10505477), 8q24.21(rs6983267), 11q13.4 (rs3824999) and 14q22.2 (rs4444235). Conclusions: Our GWAS for CRC patients from Spain confirmed some previously reported associations for CRC and yielded a novel candidate risk SNP, located at 4q26. Epistasis analyses also yielded several novel candidate susceptibility pairs that need to be validated in independent analyses. © 2014 Real et al.

BACKGROUND AND PURPOSE: Previous studies have suggested that advanced age predicts worse outcome following mechanical thrombectomy. We assessed outcomes from 2 recent large prospective studies to determine the association among TICI, age, and outcome. MATERIALS AND METHODS: Data from the Solitaire FR Thrombectomy for Acute Revascularization (STAR) trial, an international multicenter prospective single-arm thrombectomy study and the Solitaire arm of the Solitaire FR With the Intention For Thrombectomy (SWIFT) trial were pooled. TICI was determined by core laboratory review. Good outcome was defined as an mRS score of 0-2 at 90 days. We analyzed the association among clinical outcome, successful-versus-unsuccessful reperfusion (TICI 2b-3 versus TICI 0-2a), and age (dichotomized across the median). RESULTS: Two hundred sixty-nine of 291 patients treated with Solitaire in the STAR and SWIFT data bases for whom TICI and 90-day outcome data were available were included. The median age was 70 years (interquartile range, 60-76 years) with an age range of 25-88 years. The mean age of patients 70 years of age or younger was 59 years, and it was 77 years for patients older than 70 years. There was no significant difference between baseline NIHSS scores or procedure time metrics. Hemorrhage and device-related complications were more common in the younger age group but did not reach statistical significance. In absolute terms, the rate of good outcome was higher in the younger population (64% versus 44%, P < .001). However, the magnitude of benefit from successful reperfusion was higher in the 70 years of age and older group (OR, 4.82; 95% CI, 1.32-17.63 versus OR 7.32; 95% CI, 1.73-30.99). CONCLUSIONS: Successful reperfusion is the strongest predictor of good outcome following mechanical thrombectomy, and the magnitude of benefit is highest in the patient population older than 70 years of age.

Extended-spectrum-β-lactamase (ESBL)-producing Escherichia coli (ESBLEC) is an increasing cause of community and nosocomial infections worldwide. However, there is scarce clinical information about nosocomial bloodstream infections (BSIs) caused by these pathogens. We performed a study to investigate the risk factors for and prognosis of nosocomial BSIs due to ESBLEC in 13 Spanish hospitals. Risk factors were assessed by using a case-control-control study; 96 cases (2 to 16% of all nosocomial BSIs due to E. coli in the participating centers) were included; the most frequent ESBL was CTX-M-14 (48% of the isolates). We found CTX-M-15 in 10% of the isolates, which means that this enzyme is emerging as a cause of invasive infections in Spain. By repetitive extragenic palindromic sequence-PCR, most isolates were found to be clonally unrelated. By multivariate analysis, the risk factors for nosocomial BSIs due to ESBLEC were found to be organ transplant (odds ratio [OR] = 4.8; 95% confidence interval [CI] = 1.4 to 15.7), the previous use of oxyimino-β-lactams (OR = 6.0; 95% CI = 3.0 to 11.8), and unknown BSI source (protective; OR = 0.4; 95% CI = 0.2 to 0.9), and duration of hospital stay (OR = 1.02; 95% CI = 1.00 to 1.03). The variables independently associated with mortality were a Pitt score of >1 (OR = 3.9; 95% CI = 1.2 to 12.9), a high-risk source (OR = 5.5; 95% CI = 1.4 to 21.9), and resistance to more than three antibiotics, apart from penicillins and cephalosporins (OR = 6.5; 95% CI = 1.4 to 30.0). Inappropriate empirical therapy was not associated with mortality. We conclude that ESBLEC is an important cause of nosocomial BSIs. The previous use of oxyimino-β-lactams was the only modifiable risk factor found. Resistance to drugs other than penicillins and cephalosporins was associated with increased mortality.

The relationship between mineral metabolism disorders, bone fractures and vascular calcifications in kidney transplant recipients has not been established.We performed a cross-sectional study in 727 stable recipients from 28 Spanish transplant clinics. Mineral metabolism parameters, the semi-quantification of vertebral fractures and abdominal aortic calcifications were determined centrally.Vitamin D deficiency (25OHD3<15ng/ml) was more common in female recipients at CKD-T stages I-III (29.6% vs 44.4%; p=0.003). The inverse and significant correlation between 25OHD3 and PTH was gender-specific and women exhibited a steeper slope than men (p=0.01). Vertebral fractures (VFx) with deformity grade 2 were observed in 15% of recipients. Factors related to VFx differed by gender; in males, age (OR 1.04; 95% CI 1.01-1.06) and CsA treatment (OR: 3.2; 95% CI: 1.6-6.3); in females, age (OR 1.07; 95% CI: 1.03-1.12) and PTH levels (OR per 100pg/ml increase: 1.27; 95% CI: 1.043-1.542). Abdominal aortic calcifications were common (67.2%) and related to classical risk factors but not to mineral metabolism parameters.Vitamin D deficiency is more common among female kidney transplant recipients at earlier CKD-T stages, and it contributes to secondary hyperparathyroidism. Prevalent vertebral fractures are only related to high serum PTH levels in female recipients.

Background: Combination antiretroviral therapy (cART) has produced significant changes in mortality of HIV-infected persons. Our objective was to estimate mortality rates, standardized mortality ratios and excess mortality rates of cohorts of the AIDS Research Network (RIS) (CoRIS-MD and CoRIS) compared to the general population.Methods: We analysed data of CoRIS-MD and CoRIS cohorts from 1997 to 2010. We calculated: (i) all-cause mortality rates, (ii) standardized mortality ratio (SMR) and (iii) excess mortality rates for both cohort for 100 person-years (py) of follow-up, comparing all-cause mortality with that of the general population of similar age and gender.Results: Between 1997 and 2010, 8,214 HIV positive subjects were included, 2,453 (29.9%) in CoRIS-MD and 5,761 (70.1%) in CoRIS and 294 deaths were registered. All-cause mortality rate was 1.02 (95% CI 0.91-1.15) per 100 py, SMR was 6.8 (95% CI 5.9-7.9) and excess mortality rate was 0.8 (95% CI 0.7-0.9) per 100 py. Mortality was higher in patients with AIDS, hepatitis C virus (HCV) co-infection, and those from CoRIS-MD cohort (1997-2003).Conclusion: Mortality among HIV-positive persons remains higher than that of the general population of similar age and sex, with significant differences depending on the history of AIDS or HCV coinfection. © 2013 Hernando et al.; licensee BioMed Central Ltd.

Objective: to define the sociodemographic and clinical profile of patients attending the Pain Unit (PU) for the first time. Material and methods: this was an epidemiological, cross-sectional, multicenter study. Study variables were recorded on a Case Report Form. The investigators collected the sociodemographic and clinical variables of patients who attended the pain unit, complied with eligibility criteria, and gave their written informed consent to participate in the study. One hundred and sixty-five physicians from 107 Pain Units in Spanish hospitals took part in the study with a total of 823 patients. Results: mean age (SD) of patients was 59 (15.1) years; 66.4% were women. The referring specialists were orthopedics (35.1% of patients), followed by general practitioners (24.9% of patients). The mean (SD) pain intensity as measured by a numerical visual scale (NVS) was 7 (1.8). In 33.7% of patients the pain episode lasted from 3 to 12 months. 96.3% of patients presented non-oncologic pain with musculoskeletal pain predominated in 68.6%. The most common sites were the lumbar area in 55.3% of patients and the lower limbs in 40.8%. On their first visit to the Pain Unit, 7.8% of patients were receiving no analgesic treatment, while 55.2% were on non-steroid anti-inflammatory drugs (NSAIDs), 45.1% on acetaminophen, 31.6% on minor opioids, and 15.7% on major opioids. Conclusions: results show a predominance of musculoskeletal pain, which is located in the lumbar area, long-lasting, and more common in women. NSAIDs are the most common drugs prescribed by clinicians who refer patients to the Pain Unit, with opioids and antiepileptic drugs being used much less frequently. © 2011 Sociedad Española del Dolor: Published by Arán Ediciones, S.L.

Purpose To test whether combining bevacizumab, an anti-vascular endothelial growth factor treatment, with endocrine therapy (ET) could potentially delay the emergence of resistance to ET. Patients and Methods A multicenter, randomized, open-label, phase III, binational (Spain and Germany) study added bevacizumab (15 mg/kg every 3 weeks) to ET (ET-B; letrozole or fulvestrant) as first-line therapy in postmenopausal patients with human epidermal growth factor receptor 2 (HER2) -negative and hormone receptor-positive advanced breast cancer. We compared progression-free survival (PFS), overall survival (OS), overall esponse rate (ORR), response duration (RD), time to treatment failure (TTF), clinical benefit rate (CBR), and safety. Results From 380 patients recruited (2007 to 2011), 374 were analyzed by intent to-treat (184 patients on ET and 190 patients on ET-B). Median age was 65 years, 270 patients (72%) had Eastern Cooperative Oncology Group performance status of 0, 178 patients (48%) had visceral metastases, and 171 patients (46%) and 195 patients (52%) had received prior chemotherapy or ET, respectively. Median PFS was 14.4 months in the ET arm and 19.3 months in the ET-B arm (hazard ratio, 0.83; 95% CI, 0.65 to 1.06; P = .126). ORR, CBR, and RD with ET versus ET-B were 22% versus 41% (P< .001), 67% versus 77% (P = .041), and 13.3 months versus 17.6 months (P = .434), respectively. TTF and OS were comparable in both arms. Grade 3 to 4 hypertension, aminotransferase elevation, and proteinuria were significantly higher in the ET-B arm. Eight patients (4.2%) receiving ET-B died during study or within 30 days of end of treatment. Conclusion The addition of bevacizumab to ET in first-line treatment failed to produce a statistically significant increase in PFS or OS in women with HER2-negative/hormone receptor-positive advanced breast cancer. © 2015 American Society of Clinical Oncology.

Objectives: We sought to explore the immediate results of Titan2® stent implantation in small coronary arteries, as well as the incidence of major adverse cardiac events (MACE) at six months follow-up. Background: The safety of Titan2® stent has been confirmed in several studies in real-life unselected populations. Methods: We enrolled 311 consecutive patients admitted for percutaneous intervention for at least one significant (50%) de novo lesion in a native small coronary artery (2.0-2.75 mm). All lesions were treated with Titan2® stent implantation. Patients were prospectively followed up for at least six months. The primary endpoint was MACE at six months follow-up [death, myocardial infarction (MI), or target vessel revascularization (TVR)]. Secondary endpoints included angiographic and clinical procedural success, in-hospital MACE, target lesion revascularization (TLR) during follow-up, and stent thrombosis. Results: The mean age was 67.3 ± 10.9 years (65.9% males). A total of 356 Titan2® stents were implanted in 353 lesions. Angiographic and clinical procedural success was achieved in 344 (97.5%) patients. No case of in-hospital MACE or acute stent thrombosis was reported. Clinical follow-up was completed for an average of 8 ± 2 months. Two patients (0.7%) died, and 6 (2.1%) developed MI. TLR was performed in 12 (4.2%) and TVR in 16 (5.5%) patients, all were clinically driven. Cumulative MACE occurred in 20 (6.9%) patients. One patient suffered subacute stent thrombosis, but no late stent thrombosis. Conclusions: Titan2® stent implantation in small coronary arteries achieves excellent immediate outcome, with a low incidence of MACE at mid-term follow-up. © 2010 Wiley-Liss, Inc.

Background. There is little clinical information about community-onset bloodstream infections (COBSIs) caused by extended-spectrum β-lactamase (ESBL)-producing Escherichia coli (ESBLEC). We investigated the prevalence and risk factors for COBSI due to ESBLEC, and described their clinical features and the impact of COBSI caused by ESBLEC on 14-day mortality. Methods. Risk factors were assessed using a multicenter case-control-control study. Influence of ESBL production on mortality was studied in all patients with COBSI due to E. coli. Isolates and ESBLs were microbiologically characterized. Statistical analysis was performed using multivariate logistic regression. Thirteen tertiary care Spanish hospitals participated in the study. Results. We included 95 case patients with COBSI due to ESBLEC, which accounted for 7.3% of all COBSI due to E. coli. The ESBL in 83 of these (87%) belonged to the CTX-M family of ESBL, and most were clonally unrelated. Comparison with both control groups disclosed association with health care (odds ratio [OR], 2.1; 95% confidence interval [CI], 1.2-3.8), urinary catheter use (OR, 3.1; 95% CI, 1.5-6.5), and previous antimicrobial use (OR, 2.7; 95% CI, 1.5-4.9) as independent risk factors for COBSI due to ESBLEC. Mortality among patients with COBSI due to ESBLEC was lower among patients who received empirical therapy with β-lactam/β-lactam inhibitor combinations or carbapenems (8%-12%) than among those receiving cephalosporins or fluoroquinolones (24% and 29%, respectively). Mortality among patients with COBSI due to E. coli was associated with inappropriate empirical therapy irrespective of ESBL production. Conclusions. ESBLEC is an important cause of COBSI due to E. coli. Clinicians should consider adequate empirical therapy with coverage of these pathogens for patients with risk factors. © 2009 by the Infectious Diseases Society of America. All rights reserved.

Lewy body diseases (LBDs) include dementia with Lewy bodies (DLB) and Parkinson disease (PD). Alphasynuclein (AS) aggregation is a key event in the pathogenesis of LBDs and beta-synuclein (BS) inhibits AS aggregation in vitro and in vivo. Recently, BS has been shown to interact directly with AS regulating its functionality and preventing its oligomerization, and a molecular subgroup of pure DLB lacks BS in cortical regions. In this study, we characterized four new BS transcript variants and analyzed their expression in neuronal and non-neuronal tissue, and their differential expression in frozen samples of three areas from brains of patients with pure Lewy body pathology (LBP), common LBP, Alzheimer pathology, and of controls. Relative mRNA expression was determined by real-time PCR with neuron-specific enolase 2 and synaptophysin as housekeeping genes, and expression changes were evaluated by the ΔΔCt method. Two main findings are in concordance with earlier studies. First, all BS isoforms are drastically diminished in the cortex of patients with pure LBP that had presented clinically as DLB but not PD with dementia. Second, an important shift of the isoform expression ratio was observed in the temporal cortex of all LBD cases, and the minor isoforms, normally absent in the midbrain, were detected in the caudate nucleus of all DLB samples. Our results provide further evidence for the role of minor transcript variants in the development of complex diseases and provide new insights into the pathogenesis of LBDs that may be important for the understanding of molecular mechanisms involved in these complex diseases. © Springer-Verlag 2011.
